Wireless device pairing method

The present invention relates to a method of pairing wireless devices, and more particularly to a method in which a wireless device can be paired at any time.

The range of wireless communication applications has become widespread. For example, a wireless communication between a host computer and peripheral devices (such as a mouse, headphones, a microphone, and a printer) or a file transfer between wireless devices within a short distance. At present, many wireless devices such as keyboards, mice, headphones, speakers, printers, mobile computers, mobile phones, fax machines, and even digital cameras use wireless radio as a communication protocol for pairing with a computer host. There is no doubt about it.

However, there is still a deep inconvenience in the use of the wireless device. For example, a wireless keyboard and a computer host pairing must be paired before use, and the host computer needs to install an application that drives the wireless keyboard. To enable the host computer to search for the wireless keyboard, the user launches the application to pair the computer host with the wireless keyboard. Users often spend a lot of time installing applications that drive wireless keyboards or setting up programs that drive wireless devices. Therefore, the computer host pairing connection of the wireless keyboard often increases the convenience of the user operation, or increases the flow and steps of the user operation.

Second, the user can use a transceiver to pair with a wireless keyboard. The user needs to first couple the transceiver to the host computer, and press the pairing button of the transceiver and the pairing button of the wireless keyboard for a predetermined time, so that the transceiver can search for the wireless keyboard, and the user selects the wireless keyboard through the host computer. , then complete the pairing settings. Therefore, the user often presses the pairing button on both ends of the wireless keyboard and the transceiver for more than a predetermined time; or the transceiver cannot be paired with the wireless keyboard for more than a preset time; or the user presses the pairing button multiple times. The steps.

Moreover, in order to prevent the user from accidentally touching during the operation, the pairing button provided at both ends of the wireless device and the transceiver is also becoming smaller. Therefore, the user has to press the pairing button at both ends of the transceiver and the wireless device, which will cause an inconvenient step of pressing the pairing button.

Based on the above, the user installs an application that drives the wireless device; or sets a program that drives the wireless device to be paired with the wireless device; or the user presses the pairing button at both ends of the transceiver and the wireless device, and the user cannot satisfy the user. Demand. Therefore, if the wireless devices are not able to pass the application, and the pairing communication between the wireless devices can be established at any time according to the needs of the user, the convenience of pairing between the wireless devices can be improved. This is the direction worth studying.

The invention is described in detail below with reference to the accompanying drawings,

[Method of pairing wireless devices according to an exemplary embodiment of the present invention]

Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a wireless device system according to an embodiment of the invention. As shown in FIG. 1, the wireless device system 1 includes a wireless device 20 and a wireless device 10, wherein the wireless device 20 has a transceiver 202, and the wireless device 10 has a transceiver 102 and a pairing button 104, and the transceiver 202 in the wireless device 20 The transceivers 102 in the wireless device 10 transmit signals to each other via wireless transmission techniques. Here, although FIG. 1 illustrates that the wireless device 20 is a computer host and the wireless device 10 is a wireless keyboard, the wireless device 20 may actually be a notebook, a mobile phone, a tablet computer, or other suitable computing device. The wireless device 10 can also be a wireless mouse, a wireless headset, a wireless speaker, a printer, or other suitable wireless device, and the invention is not limited thereto.

It should be noted that in other embodiments, the wireless device 20 can further establish a pairing connection relationship with multiple wireless devices 10, so that each wireless device 10 uses each data address in the wireless radio to wirelessly. The device 20 performs wireless communication. For convenience of description, the method of pairing the wireless devices of the present embodiment is to establish a connection relationship between a single wireless device 20 and a single wireless device 10, as an example of wireless device pairing. The architecture of the wireless device system described in this embodiment is merely illustrative and is not limited to that shown in FIG.

In addition, although FIG. 1 illustrates that the transceiver 202 is built into the wireless device 20, the transceiver 202 can be an external wireless transceiver. The external wireless transceiver can be wireless. A universal serial bus interface (USB) or other transmission interface on the 20 is coupled to the wireless device 20. Similarly, although FIG. 1 illustrates the transceiver 102 built into the wireless device 10, the transceiver 102 can also be an external wireless transceiver that is plugged into the wireless device 10. That is, as long as the transceiver 202 and the transceiver 102 can transmit signals wirelessly, the present invention does not limit the location of the transceiver 202 and the transceiver 102, the manner of coupling, or whether it is exposed to the wireless device 20 or the wireless device 10. The surface, which is generally known to those skilled in the art, can be freely designed as needed.

Referring to FIG. 1 , the pairing button 104 is disposed on the wireless device 10 to provide a user to control the operation of the wireless device 10 by operating the pairing button 104. In particular, when the user presses the pairing button 104, the wireless device 10 can be controlled to generate a first pairing signal correspondingly, and the first pairing signal can be transmitted through the transceiver 102. Of course, the present invention does not limit the type of the mating button 104. For example, the mating button 104 can be a button, a knob, a lever, a touch device, or other suitable structure, as long as the user can operate the mating button 104 directly or indirectly. The first pairing signal is transmitted, and a person skilled in the art can freely design the pairing button 104 as needed.

From a practical point of view, please refer to FIG. 1 and FIG. 2-1 and FIG. 2-2 together. FIG. 2-1 and FIG. 2-2 are flowcharts of a method for pairing wireless devices according to an embodiment of the present invention. . As shown, when the user wants to pair the wireless device 20 with the wireless device 10, the pairing button 104 on the wireless device 10 is first pressed and the wireless device 20 is triggered by the first pairing signal generated by the wireless device 10.

That is, in the step S202, the present invention first determines whether the wireless device 10 is triggered, when the pairing button 104 is pressed, and the transceiver 102 correspondingly generates the first pairing signal. If the decision result in the step S202 is NO, the pairing button 104 of the wireless device 10 is not pressed until the pairing button 104 is pressed, and the subsequent pairing process is performed. Therefore, the user can pair with the wireless device 20 through the pairing button 104 of the wireless device 10 at any time.

If the result of the determination in step S202 is YES, step S204 is performed, so that the transceiver 102 in the wireless device 10 establishes a paired transmission channel with a preset pairing address, and transmits a first radio frequency transmission strength through the paired transmission channel. The first pairing signal is transmitted to the transceiver 202.

In practice, the transmission channel is a predetermined frequency range in the radio frequency, and in the same transmission channel, the indication attached to the packet (for example, the label attached to the packet header) can be distinguished into A plurality of data addresses for transmitting data signals (for example, when the packet has a specific indication, the packet is transmitted through one of the data addresses). For example, assuming that the transmission channel has six data addresses that can be used to transmit data signals, the method for pairing wireless devices of the present invention selects one of the data addresses to specifically pair the wireless devices, and the selected data is selected. The address is the paired address, and the remaining 5 data addresses are used to transmit data signals. In addition, the first radio frequency transmission strength may be, for example, the radio frequency transmission strength of the transceiver 102, that is, the transceiver 102 outputs the first pairing signal with the transmission power, and the first pairing signal should be a pairing request signal.

Next, in step S206, when the transceiver 102 in the wireless device 10 transmits the first pairing signal to the transceiver 202 with the first radio frequency transmission strength and the paired transmission channel, the wireless device 20 determines whether the transceiver 202 receives the first pairing. signal. If the result of the determination in the step S206 is NO, the wireless device 20 will continue to wait until the triggering of the first pairing signal is performed to perform the subsequent pairing process. If the decision result in the step S206 is YES, the wireless device 20 controls the transceiver 202 to immediately transmit the first response signal to the transceiver 102 in the paired transmission channel.

After the wireless device 20 does receive the first pairing signal, in step S208, the wireless device 20 turns on a pairing mode, and the wireless device 20 will prepare a reply packet, the reply packet includes the first communication address, and the reply packet is placed in the wireless The first in-first-out (FIFO) of the device 20, and the wireless device 20 is set to the second radio frequency transmission strength. The first communication address indicates one of a plurality of data addresses in the transmission channel that can be used to transmit a data signal. In addition, the second radio frequency transmission strength may be, for example, the radio frequency transmission strength of the transceiver 202, that is, the transceiver 202 outputs the first response signal, the second response signal, or the data signal with the transmission power.

In practice, in step S208, the wireless device 20 first determines whether the preset or randomly selected multiple data addresses are not occupied. If the preset or randomly selected multiple data addresses are not occupied, then The wireless device 20 may select one of a plurality of preset or randomly selected data addresses as the first communication address. On the other hand, if the wireless device 20 determines that a plurality of preset or randomly selected data addresses have been occupied, the wireless device 20 may select one of the unoccupied data addresses as the first communication address.

It should be noted that after the transceiver 102 does receive the first response signal, the wireless device 10 may actually wait for a period of time, or wait for the user to touch the pairing button 104 of the wireless device 10 again to proceed to step S210. For example, after the first response signal is sent, the wireless device 20 can illuminate an indicator light on the wireless device 20 to instruct the user to touch the pairing button 104 in the wireless device 10 again.

If the transceiver 102 of the wireless device 10 receives the first response signal, in step S210, it is determined whether the wireless device 10 is triggered again, when the pairing button 104 of the wireless device 10 is pressed again, and the transceiver 102 is triggered to generate correspondingly. The first pairing signal. If the result of the determination in step S210 is NO, the pairing button 104 of the wireless device 10 is not pressed, and the subsequent pairing process is not performed until the pairing button 104 is pressed.

Therefore, when the user presses the pairing button 104 in the wireless device 10 again, the wireless device 10 and the wireless device 20 enter the pairing mode. Therefore, when the user first touches the pairing button 104 in the wireless device 10 for the first time, The wireless device 10 will return the paired address to the original preset data address to prevent the wireless device 10 from disconnecting from the wireless device 20. In addition, the preset data address is, for example, a first communication address used by the wireless device 10 and the wireless device 20 to be paired; or a data address that is set by the wireless device 10 and is not paired with other wireless devices.

If the result of the determination in step S210 is YES, step S212 is performed to enable the transceiver 102 in the wireless device 10 to transmit the first pairing signal to the transceiver 202 with the first radio frequency transmission strength and the paired transmission channel.

Next, in step S212, the wireless device 10 again controls the transceiver 102 to repeatedly transmit the first pairing signal once again. Of course, as in step S204, step S212 is to transmit the first pairing signal to the transceiver 202 of the wireless device 20 on the same paired transmission channel. In other words, the wireless device 10 actually performs the process of transmitting the first pairing signal twice. In the previous process (step S204), the first pairing signal transmitted by the wireless device 10 is mainly used to trigger the activation of the wireless device 20. The wireless device 20 is switched into the pairing mode. For example, the pairing mode of the wireless device 20 includes providing the first communication address and setting the strength of transmitting the second response signal (such as the minimum transmission power), although the invention is not limited thereto, for example, the wireless device 20 The pairing mode may also include appropriate actions such as illuminating the pairing indicator, and those having ordinary skill in the art can define the components corresponding to the action after the pairing mode is activated.

After the wireless device 10 transmits the first pairing signal again, in step S214, the wireless device 20 determines whether the first pairing signal that is transmitted again is received. If not, the wireless device 20 continues to wait for the wireless device 10 to provide the first pairing. signal. If the wireless device 20 receives the first pairing signal that is transmitted again, the wireless device 20 proceeds to step S214.

Next, in step S214, the wireless device 20 determines whether the transceiver 202 receives the first pairing signal. If the result of the determination in step S214 is no, the wireless device 20 will continue to wait until the triggering of the first pairing signal to proceed to the next pairing process. If the result of the determination in step S214 is YES, the wireless device 20 controls the transceiver 202 to immediately transmit the second response signal to the transceiver 102 with the second radio frequency transmission strength and the paired transmission channel, the second response signal and the step S206 described above. The first response signal differs in that the second response signal instructs the wireless device 10 to establish a paired first communication address with the wireless device 20.

In practice, the wireless device 20 may select one of a plurality of unoccupied data addresses in the transmission channel as the first communication address after the wireless device 10 establishes pairing with the wireless device 20, and the first communication is performed. The address is placed in the FIFO register of the transceiver 202. When the wireless device 20 receives the first pairing signal again, the FIFO register of the transceiver 202 immediately transmits the second response signal to and from the wireless device 10. The second response signal includes a reply packet having a first communication address.

In step S216, the wireless device 20 considers that the connection of the wireless device 10 has been established, thereby storing the first communication address (eg, confirming the data address available to the wireless device 10) in the memory of the wireless device 20 (eg, fast). Flash memory or other suitable storage unit). At the same time, as described in step S216, the wireless device 20 can switch from the pairing mode to the data transmission mode. For example, the data transmission mode of the wireless device 20 includes setting the strength of transmitting the next data signal (resetting the maximum transmission power). Or normal transmission power), of course, the invention is not limited thereto.

In step S218, it is determined whether the wireless device 10 receives the second response signal. If the wireless device 10 does receive the second response signal, the process proceeds to step S220. In practice, the wireless device 10 receives the second response signal from the wireless device 20, and the wireless device 10 also receives the reply packet previously placed by the wireless device 20 into the FIFO. The wireless device 10 retrieves the first communication address from the reply packet and stores the first communication address, and establishes a first transmission channel with the first communication address.

As a result, the pairing process between the wireless device 20 and the wireless device 10 is completed. Finally, in step S220, after the wireless device 10 receives the second response signal, the first communication address selected by the wireless device 20 is known, and the wireless device 20 is ready to transmit the data signal. . Therefore, the wireless device 10 can also set the strength of the transmitted data signal (reset the maximum transmit power or the normal transmit power), whereby the wireless device 10 can transmit the data signal from the data address to the wireless device 20.

[Method of pairing wireless devices according to another exemplary embodiment of the present invention]

In order to make the method for pairing the wireless devices of the present invention clearer, the present embodiment details the steps of the wireless device 20 and the wireless device 10 in detail. Please refer to FIG. 1, FIG. 3-1, FIG. 3-2 and FIG. 4 together. FIG. 3-1 and FIG. 3-2 are flowcharts showing the operation steps of the wireless device 20 according to another embodiment of the present invention. FIG. A flowchart of the operational steps of the wireless device 10 in accordance with another embodiment of the present invention.

In actual operation, the wireless device 10 is in a sleep or standby state. When the user presses the pairing button 104 of the wireless device 10, the wireless device 10 will determine whether it is triggered (step S302 of FIG. 3-1), and the pairing button 104 of the wireless device 10 is pressed and triggers the transceiver 102 to generate the corresponding A pairing signal. Then, the transceiver 102 in the wireless device 10 establishes a paired transmission channel with a preset pairing address, and transmits the first pairing signal to the transceiver 102 via the paired transmission channel at the first radio frequency transmission strength, and the first radio frequency transmission The intensity is the minimum radio frequency transmission strength of the wireless device 10 (step S304).

Next, the wireless device 10 will wait for the signal to be asserted (step S306). In practice, the transceiver 102 in the wireless device 10 has a radio frequency chip, and when the transceiver 202 transmits the first response signal to the transceiver 102, the radio frequency chip of the transceiver 102 receives the first response signal and is processed internally by the radio frequency chip. A break signal will be generated. When the chopping signal is received by the wireless device 10, the wireless device 10 performs the determination of step S314.

For example, when the transceiver 202 receives the first pairing signal transmitted by the transceiver 102, the transceiver 202 will immediately transmit a first response signal to notify the transceiver 102 that the transceiver 102 is aware that the transceiver 202 has received the first Pairing signal. When the transceiver 102 receives the first response signal transmitted by the transceiver 202, and the chopping signal is received by the wireless device 10, the wireless device 10 performs the determination of step S314. In step S314, the wireless device 10 determines whether the signal is a reply packet with the first communication address. If the result of the determination in step S314 is no, the wireless device 10 proceeds to step S312, and the wireless device 10 sets the third radio frequency transmission strength. And wait for the pairing button 104 to be pressed again.

If the wireless device 10 determines that the transceiver 102 does not receive the first response signal transmitted by the transceiver 202, the transceiver 102 of the wireless device 10 performs the internal process of step S308 and step S310, and the wireless device 10 controls the transceiver 102 to re- The first pairing signal is transmitted.

In detail, the wireless device 10 determines whether the number of times the transceiver 102 transmits the first pairing signal reaches the retry upper limit value. If the result of the determination in step S308 is NO, that is, the number of times the transceiver 102 transmits the first pairing signal does not reach the retry upper limit value, the transceiver 102 retransmits the first pairing signal to the wireless device 10. If the result of the determination in step S308 is YES, then step S310 is performed. When the number of times the transceiver 102 transmits a signal reaches the retry upper limit value, the transceiver 102 suspends transmitting the first pairing signal to the wireless device 10.

If the wireless device 10 determines in step S310 whether the transceiver 102 suspends transmitting the first pairing signal, if the result of the determination in step S310 is negative, then the process returns to step S306, and the wireless device 10 continues to wait for the chopping signal. If the result of the determination in step S310 is YES, the transceiver 102 suspends transmitting the first pairing signal to the transceiver 202, and proceeds to step S312. As in step S312, the transceiver 102 in the wireless device 10 is set to a third radio frequency transmission strength, and the third radio frequency transmission strength is the maximum radio frequency transmission strength of the wireless device 10.

In practice, in step S312, the wireless device 10 also returns the pairing address to a predetermined data address, and the wireless device 10 waits to be triggered, wherein the preset data address is a plurality of data bits in a transmission channel. One of the addresses. Therefore, when the paired wireless device 10 and the wireless device 20 perform data transmission, when the user accidentally touches the pairing button 104 in the wireless device 10, the wireless device 10 and the wireless device 20 will not be disconnected, and the wireless device 10 will use the wireless device 10. The data address is preset to be transmitted with the wireless device 20. In addition, the preset data address is, for example, a first communication address used by the wireless device 10 and the wireless device 20 to complete pairing; or a data address where the wireless device 10 is not paired with other wireless devices.

It is worth mentioning that the difference between step S308 and step S310 is that when the wireless device 10 performs step S308, the number of times the transceiver 102 transmits the signal does not necessarily reach the retry upper limit value, and the wireless device 10 determines that the transceiver 102 transmits the signal. The number of times. When the wireless device 10 proceeds to step S310, the number of times the transceiver 102 transmits the signal has reached the retry upper limit value, and the wireless device 10 determines whether the transceiver 102 suspends the transmission signal. If the determination result in step S310 is YES, the wireless device 10 pauses. Transmission signal.

When the transceiver 202 in the wireless device 20 does not receive the first pairing signal, the wireless device 20 waits for the signal to be chopped (as in step S400), and when the transceiver 202 in the wireless device 20 receives the first pairing signal, proceeds to step S402. In practice, the transceiver 202 in the wireless device 20 has a radio frequency chip, and when the transceiver 102 transmits the first pairing signal to the transceiver 202, the radio frequency chip of the transceiver 202 receives the first pairing signal and is processed internally by the radio frequency chip. A break signal will be generated. When the chopping signal is received by the wireless device 20, the wireless device 20 performs the determination of step S402.

If the decision result in the step S402 is NO, the wireless device 20 continues to wait for the disconnection signal from the wireless device 10 (step S400). If the wireless device 20 determines that the transceiver 102 completely receives the first pairing signal (step S402), the wireless device 20 determines whether the first pairing signal is a pairing request signal (step S404). Then, if the wireless device 20 determines whether the first pairing signal is from the pairing address in the paired transmission channel (step S406); if the result of the determination in step S406 is no, the wireless device 20 further determines whether the signal is a data signal (step S414). ).

If the wireless device 20 determines that the signal is not from the pairing address in the transmission channel, the wireless device 20 determines that the received signal is generated by a malfunction, so it will continue to wait for the disconnection signal (step S400); if the wireless device 20 determines the signal From the pairing address in the transmission channel, the wireless device 20 determines whether the pairing mode is on (as in step S408).

It is worth mentioning that the pairing mode of the wireless device 20 in this embodiment is originally set to off. When the transceiver 102 transmits the first pairing signal to the transceiver 102, the wireless device 20 turns on the pairing mode, the wireless device 20 switches the pairing mode to on (as in step S410); when the transceiver 102 transmits the first pairing signal to the transceiver 102 again When the wireless device 20 enters the pairing mode, the wireless device 20 switches the pairing mode to off (as in step S412), ie the pairing mode of the wireless device 20 will revert to the original setting. The pairing mode original setting of the wireless device 20 in this embodiment is merely illustrative, and is not limited to that shown in FIG.

Assuming that the pairing mode of the wireless device 20 is originally set to off, the result of the determination in step S408 is NO. In step S410, the wireless device 20 turns on the pairing mode to switch the pairing mode to on. The wireless device 20 will prepare a ready-to-receive packet, the replies packet including the first communication address, and the replies packet placed in the FIFO register of the wireless device 20. In addition, the wireless device 20 sets the transceiver 202 to a second radio frequency transmission strength, and the second radio frequency transmission strength is a minimum radio frequency transmission strength of the wireless device 20.

Here, the second radio frequency transmission strength may be, for example, the minimum radio frequency transmission strength of the transceiver 202, that is, the transceiver 202 outputs the second response signal with the minimum transmission power. That is, only the transceiver 102 is located within a predetermined distance of the transceiver 202. When the user presses the pairing button 104 on the wireless device 10, the first pairing signal output by the transceiver 102 is received by the wireless device 20. The transceiver 202 receives it. If the distance between the transceiver 102 and the transceiver 202 exceeds the preset distance, the transceiver 102 and the transceiver 202 cannot effectively transmit signals, so that the wireless device 20 and the wireless device 10 cannot perform the matching process. In terms of practical use, if there are multiple wireless devices 20 (such as a computer host) in one space, and each of the transceivers 102 does not output the first pairing signal with the minimum transmit power, the wireless will be enabled. Device 10 (such as a wireless keyboard) is simultaneously paired to multiple wireless devices 20 (such as a computer host), which is clearly not the most advantageous use.

In practice, the strength of the first RF transmission strength affects the distance between the transceiver 202 and the transceiver 102. The strong first RF transmission strength allows the transceiver 202 to receive signals from the transceiver 102 at a greater distance. It can be seen that when the transceiver 102 is set to the minimum RF transmission strength, the transceiver 102 can be paired with the transceiver 202 within a relatively short distance to avoid malfunction with other wireless devices. In other words, when the transceiver 202 and the transceiver 102 respectively output the first pairing signal and the second response signal with the minimum transmission power, only the closest two wireless devices are likely to perform the pairing process, thus The present invention enables one-to-one wireless pairing in a specific space.

For example, transceiver 202 is, for example, a radio frequency transceiver that is plugged into a universal serial bus interface (USB) of wireless device 20. When the transceiver 102 of the wireless device 10 is located within about 40 centimeters of the transceiver 202, the wireless device 10 can be enabled to efficiently transmit the first pairing signal to the transceiver 202 of the wireless device 20. When the transceiver 202 of the wireless device 20 receives the first pairing signal, the wireless device 20 may first set the transmit power of the transceiver 202 to a minimum such that the wireless device 20 can effectively transmit the second response signal to the transceiver 102. Please note that the minimum transmit power of the transceiver 202 and the transceiver 102 are not necessarily the same. For example, the transceiver 202 can enable the transceiver 102 within 40 cm to effectively receive signals, and the transceiver 102 can enable the transceiver 202 within 30 cm to effectively receive signal.

When the user presses the pairing button 104 of the wireless device 10 again, the wireless device 10 will determine whether it is triggered again (as in step S302), and the pairing button 104 of the wireless device 10 is pressed again and triggers the transceiver 102 to generate the first pairing accordingly. signal. Next, the transceiver 102 in the wireless device 10 transmits the first pairing signal to the transceiver 202 with the first radio frequency transmission strength and the paired transmission channel, and the first radio frequency transmission strength is the minimum radio frequency transmission strength of the wireless device 10 (steps) S304).

After the transceiver 102 transmits the first pairing signal to the transceiver 202 in the wireless device 20, the wireless device 20 performs the procedures of steps S400 to S408, and the flow of steps S400 and S408 is not described herein again. When the wireless device 20 performs the determination of step S408, if the wireless device 20 determines that the pairing mode is on in step S408, step S412 is performed. In step S412, the wireless device 20 enters the pairing mode, and the wireless device 20 switches the pairing mode to off. The wireless device 20 stores the first communication address to the memory and sets the transceiver 202 to a fourth RF transmission strength, and the fourth RF transmission strength is the maximum RF transmission strength of the wireless device 20. Thereafter, the wireless device 20 leaves the pairing mode.

It should be noted that after the transceiver 202 of the wireless device 20 receives the first pairing signal transmitted by the transceiver 102 of the wireless device 10, the transceiver 202 immediately transmits the second response signal to the transceiver in the wireless device 10 in the paired transmission channel. If the wireless device 10 receives the second response signal from the wireless device 20, the wireless device 10 also receives the reply packet that the wireless device 20 previously placed in the FIFO register. The wireless device 10 retrieves the first communication address from the reply packet and stores the first communication address, and establishes a first transmission channel with the first communication address.

In detail, if the wireless device 10 determines that the transceiver 102 receives the second response signal transmitted by the transceiver 202 immediately, the wireless device 10 performs the determination of step S314 after receiving the disconnection signal. In step S314, it is determined whether the wireless device 10 receives the signal as a reply packet having the first communication address. If the determination result in step S314 is YES, the process proceeds to step S316. In step S316, it is determined whether the first communication address is obtained. It is assumed that the wireless device 10 receives the second response signal and obtains the first communication address from the reply packet. In step S318, the wireless device 10 uses the first communication address. A first transmission channel is established and the first communication address is stored in the memory. At this time, the wireless device 10 sets the transceiver 102 to the third radio frequency transmission strength, and the third radio frequency transmission strength is the maximum radio frequency transmission strength of the wireless device 10.

The wireless device 10 determines that the transceiver 102 does not receive the second response signal transmitted by the transceiver 202, and then the wireless device 10 performs the steps S308 and S310 to retransmit the first pairing signal, and the steps S308 and S310 are performed. The process is not repeated here.

Therefore, in step S320, the wireless device 20 and the wireless device 10 enter the normal operation mode, and the wireless device 20 completes pairing with the wireless device 10 and performs bidirectional transmission of the data signal. The wireless device 20 transmits the data signal to the wireless device 10 at the fourth radio frequency transmission strength and the first transmission channel.

It is worth mentioning that the transceiver 102 transmits the data signal to the transceiver 202 of the wireless device 20 with the third radio frequency transmission strength and the first transmission channel, and the wireless device 20 performs the procedures of step S400 to step S404, assuming that the wireless device 20 determines not When the request signal is paired (step S404), step S414 is performed, and the wireless device 20 determines whether it is a data signal. If the result of the determination in step S404 is YES, the data transmission is performed in the first transmission channel (step S416); if the determination in step S404 is negative, the process returns to step S400, and the wireless device 20 continues to wait for the chopping signal.

[Method of pairing wireless devices according to another exemplary embodiment of the present invention]

In order to make the method of pairing the wireless device of the present invention clearer, the present embodiment details the flow of another step of the wireless device 20 and the wireless device 10 herein. Please refer to FIG. 1, FIG. 3-1, FIG. 3-2 and FIG. 5. FIG. 5 is a partial operational flowchart of a method for pairing wireless devices according to another embodiment of the present invention. The difference in the operational flow of the wireless device 10 in FIG. 5 and FIG. 3-1 and FIG. 3-2 is that the pairing button 104 of the wireless device 10 in FIG. 5 is pressed once, and the transceiver 102 of the wireless device 10 transmits the second time. The pairing signal is pressed twice with the pairing button 104 of the wireless device 10 in FIGS. 3-1 and 3-2 of the above embodiment, and the flow of steps corresponding to the generation of the first pairing signal is different.

In detail, when the user wants to pair the wireless device 20 with the wireless device 10, the pairing button 104 on the wireless device 10 is first pressed, and the wireless device 20 is triggered by the first pairing signal generated by the wireless device 10. That is to say, in the step S502, the present invention first determines whether the wireless device 10 is triggered. When the pairing button 104 is pressed, the transceiver 102 correspondingly generates a first pairing signal. The transceiver 102 in the wireless device 10 is caused to transmit the first pairing signal to the transceiver 202 with the first radio frequency transmission strength and the paired transmission channel (step S504).

Next, the wireless device 10 enters a wait-off signal (step S506). The wireless device 20 determines whether the transceiver 202 has received the first pairing signal. If so, the wireless device 20 controls the transceiver 202 to immediately transmit the first response signal to the transceiver 102 in a paired transmission channel. After the transceiver 102 does receive the first response signal, the transceiver 102 also generates a chopping signal. After receiving the chopping signal, the transceiver 102 proceeds to step S508 to determine whether the wireless device 10 receives the signal as having the first communication. The reply packet of the address, wherein the first response signal transmitted by the wireless device 20 for the first time does not have the reply packet of the first communication address, so the wireless device 10 proceeds to step S510 to determine whether the wireless device 10 receives the first response signal.

When the wireless device 10 determines to receive the first response signal, the wireless device 10 controls the transceiver 102 to be automatically triggered again and correspondingly generates a first pairing signal. The wireless device 10 is caused to retransmit the first pairing signal to the transceiver 202 with the first radio frequency transmission strength and a paired transmission channel (step S504). In addition, when the wireless device 10 determines that the reception is not the first response signal, the process proceeds to step S512, and the wireless device 10 sets the third radio frequency transmission strength. The wireless device 10 replies the paired address to a predetermined data address.

In practice, the transceiver 102 is, for example, designed to receive the first response signal, the transceiver 102 automatically generates the first pairing signal again, and transmits the first pairing signal to the transceiver 202 in the wireless device 20; or when wireless After the pairing button 104 of the device 10 is pressed, the first pairing signal and the second pairing signal are generated correspondingly, and the second pairing signal is separated from the first pairing signal by the first time. The time is then transmitted to the wireless device 20. The present invention does not limit the manner and number of times that the transceiver 102 generates the first pairing signal after the pairing button 104 of the wireless device 10 is pressed. The person skilled in the art can freely design as needed.

Next, the transceiver 102 automatically generates the first pairing signal again and transmits the first pairing signal to the transceiver 202 of the wireless device 20. If the transceiver 202 in the wireless device 20 receives the first pairing signal, the wireless device 20 transmits a second response signal to the transceiver 102 of the wireless device 10 with the second RF transmission strength and the paired transmission channel. When the transceiver 102 confirms receiving the second response signal, the transceiver 102 performs the determination of step S508. If the wireless device 10 receives the signal as the reply packet with the first communication address, the process proceeds to step S514, and the wireless device 10 obtains the first communication. The address is set, and the first transmission channel is established by the first communication address, and the wireless device 10 and the wireless device 20 transmit the data signal through the first transmission channel.

[Method of pairing wireless devices according to another exemplary embodiment of the present invention]

In order to make the method of pairing the wireless devices of the present invention clearer, the present embodiment details the flow of steps of the wireless device 20 and the plurality of wireless devices 10, 12, and 14 in this embodiment. Referring to FIG. 6, FIG. 6 is a schematic diagram of a system architecture of a method for pairing multiple wireless devices 10, 12, 14, and 20 according to another embodiment of the present invention. Wireless device system 1a includes wireless device 20 and wireless devices 10, 12, 14, and wireless devices 10, 12, 14 each have transceivers 102, 122, 142 and pairing buttons 104, 124, 144.

For example, the wireless device 20 establishes a dedicated paired transmission channel with a fixed pairing address, and the wireless device 20 selects and determines the first communication bit. The address (or the second communication address; or the third communication address) is used to notify the wireless device 10, 12, 14. The difference between the wireless devices 10, 12, 14 in FIG. 6 with respect to FIG. 1 is that the wireless devices 10, 12, 14 establish a paired transmission channel with a paired address and use the first communication address (or the second communication bit). The address or the third communication address is used to update the paired transmission channel as the first transmission channel (or the second transmission channel; or the third transmission channel).

As described in the above embodiments of the present invention, when the wireless device 20 is paired with the wireless device 10, the wireless device 20 can be paired with the wireless devices 12, 14. The wireless device 12, 14 includes, but is not limited to, a wireless mouse, a wireless headset, a wireless speaker, a printer, or other suitable wireless device, and the invention is not limited thereto. When the wireless device 12 is paired with the wireless device 20, it is determined whether the wireless device 12 is triggered. If so, the wireless device 12 establishes a paired transmission channel with a preset pairing address, and transmits a fifth radio frequency via the paired transmission channel. Intensity, the second pairing signal is transmitted to the wireless device 20.

Determining whether the wireless device 20 receives the second pairing signal, and if so, the wireless device 20 transmits the first response signal to the wireless device 12 in the paired transmission channel, the wireless device 20 turns on the pairing mode, and stores the second communication address in the wireless device 20 The second FIFO register, and the wireless device 20 sets the second RF transmission strength.

It is determined whether the wireless device 12 is triggered again, and if so, the wireless device 12 transmits the second pairing signal to the wireless device 20 with the fifth radio frequency transmission strength and the paired transmission channel. The fifth radio frequency transmission strength is the minimum radio frequency transmission strength of the wireless device 12.

Determining whether the wireless device 20 receives the second pairing signal again. If yes, the wireless device 20 transmits the second response signal to the wireless device 12 by using the second RF transmission strength and the paired transmission channel, and the wireless device 20 enters the pairing mode, and the multiplexer is ready to reply. The packet, the reply packet includes a second communication address, and the reply packet is placed in the FIFO register of the wireless device 20.

If the wireless device 12 receives the second response signal from the wireless device 20, the wireless device 12 also receives a reply packet previously placed by the wireless device 20 into the FIFO register. The wireless device 12 retrieves the second communication address from the reply packet and stores the second communication address, and establishes a second transmission channel with the second communication address. Therefore, the wireless device 12 and the wireless device 20 perform data transmission through the second transmission channel.

Similarly, the wireless device 14 is paired with the wireless device 20, the wireless device 20 selects the third communication address, and notifies the wireless device 14 to establish a third transmission channel using the third communication address, and the wireless device 14 and the wireless device 20 Data transmission through the third transmission channel. The method of pairing wireless devices of the present invention can be applied to a single wireless device 20 to a plurality of wireless devices 10, 12, 14 and selected by a single wireless device 20 and determining a communication address paired with each wireless device 10, 12, 14. For example, it is a first communication address, a second communication address or a third communication address.

It is worth mentioning that when the wireless device 10 is paired with the wireless device 20, the wireless device 20 selects and determines the communication address. When the wireless device 10 occupies the first communication address and the wireless device 20 is paired with the wireless device 12, the wireless device 20 does not select the occupied data address (such as the first communication address), and the wireless device 20 is never The occupied data address (such as the second communication address, the third communication address or the fourth communication address, etc.) selects and determines the communication address, so the wireless device 12 occupies the second communication address, and the wireless device 14 occupies the Three communication addresses.

For example, the host can be paired with a wireless keyboard, a first wireless mouse, and a second wireless mouse. When the host is paired with the wireless keyboard, the host selects and decides to use the first communication address to perform bidirectional data transmission with the wireless keyboard. Therefore, the first transmission channel is established between the host and the wireless keyboard by using the first communication address for bidirectional data transmission. Similarly, the host selects and decides to establish a second transmission channel by using the second communication address to perform bidirectional data transmission with the first wireless mouse, and the host selects and decides to establish a third transmission channel by using the third communication address. Two-way data transmission with the second wireless mouse.
