Example 1
Fig. 1 is a flowchart illustrating an automatic bluetooth connection method according to a first embodiment of the present invention.
The Bluetooth automatic connection method is applied to a second Bluetooth unit, the second Bluetooth unit can be a Bluetooth voice processing unit, and the Bluetooth voice processing unit comprises a Bluetooth TV terminal, a Bluetooth mobile terminal, a Bluetooth server terminal and the like.
The Bluetooth automatic connection method comprises the following steps:
in step S110, a page sent by the first bluetooth unit is scanned, and a first response message to the page is sent to the first bluetooth unit.
Specifically, in the process of establishing a connection between the first bluetooth unit and the second bluetooth unit, two connection processes are required, the first connection process is a pairing process, and the second connection process is a connection process.
Any wireless communication technology has the possibility of being monitored and cracked, Bluetooth adopts an authentication mode to carry out data interaction in order to ensure the safety, and the authentication process is the pairing process. In order to ensure the convenience of Bluetooth use, the first communication authentication between the first Bluetooth unit and the second Bluetooth unit is completed in a pairing mode, and after the first Bluetooth unit and the second Bluetooth unit are paired, the first Bluetooth unit and the second Bluetooth unit do not need to be authenticated each time in the process of establishing connection each time.
The first Bluetooth unit is used as a master device for initiating a connection request, firstly, a paging is initiated to the second Bluetooth unit in a frequency hopping mode in a Bluetooth working frequency band, the second Bluetooth unit is used as a slave device for receiving the connection request, and the paging is scanned from each frequency hopping in the Bluetooth working frequency band at intervals of preset time.
Of course, the second bluetooth unit may scan for at least one page indicating that it received a connection request from multiple first bluetooth units.
Upon receiving a page, the second bluetooth unit, after scanning the page, generates a first response message (which may also be an ACK message) for the page and sends the first response message to the first bluetooth unit that initiated the page.
When a plurality of pages are received, after the second Bluetooth unit scans the pages, a first response message is generated for each page, and the first response message is sent to a paging initiating terminal corresponding to the first response message, namely, the first Bluetooth unit corresponding to the first response message.
In step S120, after pairing with the first bluetooth unit is successful, the MAC address is sent to the first bluetooth unit to store the MAC address by the first bluetooth unit.
Specifically, after receiving the first response message, the first bluetooth unit regards that the second bluetooth unit initiating the first response message agrees to the pairing request, and then pairs with the second bluetooth unit, which may also be regarded as establishing a connection of an ACL link.
After the first Bluetooth unit and the second Bluetooth unit are successfully paired, the subsequent high-level connection which is different from classic Bluetooth and is established by using PIN codes or agreed keys is established, the second Bluetooth unit directly sends the MAC address of the second Bluetooth unit to the first Bluetooth unit as a connection password, the first Bluetooth unit receives and stores the MAC address, and in the mode, the MAC address is information carried by each Bluetooth unit, and the MAC addresses of the Bluetooth units are different, so that the steps of generating the PIN codes or the agreed passwords are not needed, the subsequent connection is directly performed through the MAC address, the connection safety is improved, and the connection period is shortened.
In step S130, when the first bluetooth unit is triggered to set the connection protocol in advance, the MAC address sent by the first bluetooth unit is received.
Specifically, after the first bluetooth unit triggers the preset connection protocol, the first bluetooth unit initiates a connection request to the second bluetooth unit, and sends the stored MAC address to the second bluetooth unit in a broadcast manner. The predetermined connection protocol includes a point-to-point protocol and a point-to-multipoint protocol, that is, bluetooth supports point-to-point connection and also supports point-to-multipoint connection.
Of course, the transmitting MAC address can still be broadcast in a frequency hopping fashion.
In step S140, it is determined whether the MAC address matches the MAC address of the host.
Specifically, when the MAC address is scanned, the second bluetooth unit compares the scanned MAC address with its own MAC address, determines whether the MAC address is consistent with its own MAC address, and if so, indicates that the MAC address is successfully verified, and proceeds to step S160; if the MAC address is not consistent with the MAC address of the MAC address itself, it indicates that the MAC address verification fails and the current connection is in error, and the process proceeds to step S150.
The MAC address replaces the PIN code or the appointed password, and due to the uniqueness of the MAC address, the safety problem that the PIN code or the appointed password is cracked can be solved, and meanwhile, the steps of actively generating the PIN code or the appointed password are reduced. In addition, after the Bluetooth triggers the preset connection protocol, the first Bluetooth unit can be automatically triggered to actively broadcast the stored MAC address, after the second Bluetooth unit receives the MAC address, the MAC address is respectively compared with the MAC address of the second Bluetooth unit, if the MAC address is consistent with the MAC address, the first Bluetooth unit and the second Bluetooth unit can be automatically connected, the connection period among the Bluetooth units is shortened, the connection speed is increased, and automatic connection can be realized.
If only one second bluetooth unit exists in the current environment and the first bluetooth unit broadcasts only one MAC address (the MAC address is the stored MAC address of the second bluetooth unit), the second bluetooth unit compares only the received one MAC address with its own MAC address to obtain a consistent comparison result, and then proceeds to step S160. Certainly, there is also an address broadcasted by the first bluetooth unit as an erroneous MAC address (for example, the first bluetooth unit selects an erroneous MAC address from the stored MAC addresses to broadcast), then the comparison result of the second bluetooth unit at this time is inconsistent, and the process proceeds to step S150 to prompt a message that the MAC addresses are inconsistent.
In step S150, a message indicating this connection failure is presented.
In step S160, a connection is established directly with the first bluetooth unit.
Specifically, the second bluetooth unit determines that the MAC address sent by the scanned first bluetooth unit is consistent with its own MAC address, which means that the MAC address is verified, and then the second bluetooth unit directly establishes connection with the first bluetooth unit.
Example 2
Fig. 2 is a flowchart illustrating an automatic bluetooth connection method according to a second embodiment of the present invention.
The Bluetooth automatic connection method is applied to a second Bluetooth unit, the second Bluetooth unit can be a Bluetooth voice processing unit, and the Bluetooth voice processing unit comprises a Bluetooth TV terminal, a Bluetooth mobile terminal, a Bluetooth server terminal and the like.
In step S210, a page sent by the first bluetooth unit is scanned, and a first response message to the page is sent to the first bluetooth unit.
This step is the same as step S110, and is not described herein again.
In step S220, it is determined whether a MAC address needs to be sent to the first bluetooth unit.
Specifically, after receiving first response information sent by a second bluetooth unit, a first bluetooth unit is paired with the second bluetooth unit. After the pairing is successful, the second bluetooth unit determines whether the MAC address needs to be sent to the first bluetooth unit, which means that the second bluetooth unit determines whether to establish connection with the first bluetooth unit in the automatic connection manner described in this embodiment, and if the second bluetooth unit is connected with the first bluetooth unit in the automatic connection manner, the MAC address needs to be sent to the first bluetooth unit, and the process proceeds to step S230; if the connection with the first bluetooth unit is not performed by the automatic connection method (which can be regarded as a method of performing a general bluetooth connection), the MAC address does not need to be transmitted to the first bluetooth unit, and the process proceeds to step S240.
In this embodiment, the second bluetooth unit may set an option, where the option includes two schemes, the first scheme is a connection through a general bluetooth connection mode, and the second scheme is a connection through an automatic connection mode, and if the user selects the first scheme, because the general bluetooth connection mode does not need a MAC address, but generates a PIN code or an agreed password, the MAC address is not sent to the first bluetooth unit; if the user selects the second scheme, the MAC address is sent to the first Bluetooth unit.
In other embodiments, a default connection mode may be preset, the second bluetooth unit obtains information of the default connection mode, and if the default connection mode is an automatic connection mode, the MAC address is sent to the first bluetooth unit; if the default connection mode is a normal Bluetooth connection mode, the MAC address is not sent to the first Bluetooth unit.
In step S230, after pairing with the first bluetooth unit is successful, the MAC address is sent to the first bluetooth unit to store the MAC address by the first bluetooth unit.
In step S240, the connection request sent by the first bluetooth unit is received, and second response information to the connection request is sent to the first bluetooth unit.
Specifically, when the second bluetooth unit determines to establish connection with the first bluetooth unit through a general bluetooth connection mode, the first bluetooth unit initiates a connection request to the second bluetooth unit, and after receiving the connection request sent by the first bluetooth unit and responding to the confirmation operation of the user on the connection request, the second bluetooth unit sends second response information to the connection request to the first bluetooth unit.
It should be noted that the operation of confirming the connection request by the user may include an operation of verifying whether the PIN code or the agreed password is consistent with the PIN code or the agreed password in the first bluetooth unit, if so, the verification is passed, and the connection request is confirmed, otherwise, the connection request is not confirmed, and the connection is not performed.
In step S250, when the first bluetooth unit is triggered to the preset connection protocol, the MAC address transmitted by the first bluetooth unit is received.
This step is the same as step S130, and is not described herein again.
In step S260, it is determined whether the MAC address matches the MAC address of the host.
The second bluetooth unit determines whether the MAC address is consistent with its own MAC address, and if so, proceeds to step S280, otherwise, proceeds to step S270.
In step S270, a message indicating that the connection has failed this time is presented.
In step S280, a connection is established directly with the first bluetooth unit.
The embodiment of the present invention further provides a second bluetooth unit, where the second bluetooth unit includes a second memory and a second processor, the second memory is used for storing a computer program, and the second processor runs the computer program to enable the second bluetooth unit to execute the above-mentioned bluetooth automatic connection method.
Example 3
Fig. 3 is a flowchart illustrating a method for initiating a bluetooth connection according to a third embodiment of the present invention.
The method for initiating the Bluetooth connection is applied to a first Bluetooth unit, wherein the first Bluetooth unit is a Bluetooth pickup unit, and the Bluetooth pickup unit comprises a Bluetooth earphone, a Bluetooth black ear, a Bluetooth necklace, a Bluetooth bracelet, a Bluetooth ring and the like.
In step S310, a page is initiated to the second Bluetooth unit and response information of the second Bluetooth unit to the page is received.
Specifically, a first bluetooth unit, as a master device initiating a connection request, first initiates a page to a second bluetooth unit in a frequency hopping manner within a bluetooth operating frequency band, and the second bluetooth unit, as a slave device receiving the connection request, scans the page from each frequency hopping within the bluetooth operating frequency band at preset time intervals and responds to the page.
In step S320, the second bluetooth unit is paired according to the response information.
Specifically, the first bluetooth unit directly pairs with the second bluetooth unit according to the received response information sent by the second bluetooth unit.
In step S330, after the pairing is successful, the MAC address sent by the second bluetooth unit is received.
Specifically, after the pairing is successful, the first bluetooth unit receives the MAC address sent by the second bluetooth unit, and stores the MAC address in the local storage unit.
In step S340, after triggering the predetermined connection protocol in the predetermined starting manner, the MAC address is sent to the second bluetooth unit in a broadcast manner, so that the second bluetooth unit directly establishes a connection when the MAC address is consistent with the MAC address of the second bluetooth unit.
Further, the preset starting mode comprises triggering a preset key for a preset number of times continuously or triggering the preset key and maintaining a preset time.
Specifically, the first bluetooth unit is provided with a predetermined key, and the predetermined key may be a physical key or a virtual key. In this embodiment, the existing start key may be used as the predetermined key. Of course, in some other embodiments, a new key may be provided on the first bluetooth unit, and the new key is used to trigger the predetermined connection protocol.
The predetermined connection protocol includes a point-to-point protocol and a point-to-multipoint protocol. Typically, two bluetooth units are connected via a point-to-point protocol. More than two Bluetooth units can be connected through a point-to-multipoint protocol.
For example, the user may activate the activation key of the first bluetooth unit 2 times or activate the activation key of the first bluetooth unit and maintain for 3 seconds, etc. in succession.
After triggering the preset connection protocol, the first bluetooth unit can establish a connection with the second bluetooth unit, and the process of establishing the connection is as follows: the first Bluetooth unit broadcasts the stored MAC address in a broadcasting mode.
And after scanning the MAC address broadcast by the first Bluetooth unit, the second Bluetooth unit judges whether the MAC address is consistent with the MAC address of the second Bluetooth unit, and if so, the second Bluetooth unit directly establishes connection with the first Bluetooth unit.
Further, before receiving and storing the MAC address sent by the second bluetooth unit, the method further includes:
when the MAC address sent by the second Bluetooth unit is not received, sending a connection request to the second Bluetooth unit, and receiving second response information sent by the second Bluetooth unit; and establishing connection with the second Bluetooth unit according to the second response information.
Specifically, when the second bluetooth unit determines not to send the MAC address to the first bluetooth unit, and establishes a connection with the first bluetooth unit in a general bluetooth connection manner, the first bluetooth unit initiates a connection request to the second bluetooth unit, and after receiving the connection request sent by the first bluetooth unit, the second bluetooth unit responds to a confirmation operation of the user on the connection request, and sends second response information to the connection request to the first bluetooth unit.
It should be noted that the operation of confirming the connection request by the user may include an operation of verifying whether the PIN code or the agreed password is consistent with the PIN code or the agreed password in the first bluetooth unit, if so, the verification is passed, and the connection request is confirmed, otherwise, the connection request is not confirmed, and the connection is not performed.
The embodiment of the present invention further provides a first bluetooth unit, where the first bluetooth unit includes a first memory and a first processor, the first memory is used for storing a computer program, and the first processor runs the computer program to enable the first bluetooth unit to execute the above method for initiating a bluetooth connection.
Example 4
Fig. 4 is a schematic structural diagram illustrating a voice control system according to a second embodiment of the present invention. The voice control system 400 includes a first bluetooth unit 410 and a second bluetooth unit 420.
The automatic bluetooth connection method in embodiment 1 and embodiment 2 is fully applicable to the second bluetooth unit in this embodiment, and the method of initiating a bluetooth connection in embodiment 3 is fully applicable to the first bluetooth unit 410 in this embodiment.
After the first bluetooth unit 410 establishes a connection with the second bluetooth unit 420, the first bluetooth unit 410 is configured to collect voice information of a user, and send the voice information to the second bluetooth unit 420.
The second bluetooth unit 420 is configured to parse the voice information to obtain a control command, so as to control interaction between the second bluetooth unit and the first bluetooth unit 410 according to the control command.
Specifically, as shown in fig. 5, two bluetooth units are taken as an example to describe the process of establishing connection between the first bluetooth unit 410 and the second bluetooth unit 420:
a1: the first bluetooth unit 410 initiates paging to the second bluetooth unit 420 by means of frequency hopping;
a2: the second bluetooth unit 420 scans for pages within each frequency hopping band;
a3: after scanning the page initiated by the first bluetooth unit 410, the second bluetooth unit 420 responds to the page and sends a first response message to the first bluetooth unit 410;
a4: the first bluetooth unit 410 matches the second bluetooth unit 420 after receiving the first response message;
a5: after the pairing is successful, the second bluetooth unit 420 determines whether to send the MAC address to the first bluetooth unit 410;
a6: if the determination result is yes, the second bluetooth unit 420 sends its own MAC address to the first bluetooth unit 410;
a7: after receiving the MAC address, the first bluetooth unit 410 stores the MAC address in a local memory;
a8: the first bluetooth unit 410 triggers a point-to-point protocol through a preset starting mode;
a9: after triggering the point-to-point protocol, the first bluetooth unit 410 broadcasts out the stored MAC address;
a10: the second bluetooth unit 420 scans all broadcasts to obtain the MAC address sent by the first bluetooth unit 410, and compares the MAC address with its own MAC address to determine whether to establish a connection with the first bluetooth unit 410;
a11: the second bluetooth unit 420 establishes a point-to-point connection directly with the first bluetooth unit 410 after the MAC address coincides with its own MAC address.
The above whole signaling interaction process realizes the automatic connection between the first bluetooth unit 410 and the second bluetooth unit 420, and the automatic verification is performed by uniquely identifying the MAC address without the steps of confirming the PIN code or agreeing the password by both parties.
It is noted that the proprietary protocol specified in the signaling interaction process is supported in both the first bluetooth unit 410 and the second bluetooth unit 420.
After the first bluetooth unit 410 establishes a connection with the second bluetooth unit 420, the first bluetooth unit 410 collects voice information of a user and transmits the voice information to the second bluetooth unit 420 through the bluetooth connection.
The second bluetooth unit 420 analyzes the voice information through a voice decoding device or program to obtain a control command, so as to control the interaction between the second bluetooth unit 420 and the first bluetooth unit 410 according to the control command.
Wherein, first bluetooth unit 410 can be the bluetooth pickup unit, the bluetooth pickup unit includes bluetooth headset, bluetooth ear-shaped earphone, bluetooth necklace, bluetooth bracelet and bluetooth ring etc..
The second bluetooth unit 420 is a bluetooth voice processing unit, and the bluetooth voice processing unit includes a bluetooth TV terminal, a bluetooth mobile terminal, a bluetooth server terminal, and the like.
The application scenarios of the bluetooth sound pickup unit and the bluetooth voice processing unit may include: for example, the current scenario of a TV interacting with a user by voice can be divided into near-field voice and far-field voice. Wherein near field speech is typically equipped with a bluetooth wireless communication module. However, in near-field speech, the sound pickup unit for intelligent speech interaction is often performed through a remote controller, and a call can be made only by holding the remote controller of the TV with a hand and pressing a speech key. In order to release hands and enable a voice interaction mode to be more natural, a user can interact with a TV in a far-field voice mode, and the core difference between a far field and a near field from an application scene is that the step of pressing a voice key is omitted, the distance between the user and a voice device is pulled, and two hands are thoroughly liberated, so that the mode is closer to a natural voice interaction mode.
At present, far-field voice needs a microphone array mode, words need to be awakened, the voice is limited by multiple complex factors such as background noise, other sound interference, echo and reverberation, the identification distance cannot be far, the identification has directivity, the identification rate is low, and the like, so that obvious pain points are caused, the user requirements cannot be met due to the fact that voice interaction experience is not satisfactory in many scenes, particularly, the problem of mistaken awakening exists, the problem that a half-night TV is frequently awakened to start up by mistake is solved, and the user experience is seriously influenced. In addition, when the far-field sound pickup unit is in standby, the far-field sound pickup unit needs to be kept working, so that the standby power consumption is high, and the regulation requirement of the standby power consumption cannot be met (the regulation requirement of the Chinese market requires that the standby power consumption is less than 0.5 w).
Therefore, through the wearable Bluetooth pickup unit, for example, interaction is performed between the Bluetooth headset and the TV, after the Bluetooth headset is connected with the TV, the TV end is switched to a Bluetooth headset mode, the loudspeaker box of the TV end is closed, and a control command is sent to the TV through the Bluetooth headset and all sound information sent by the TV is received for playing.
However, the current bluetooth headset and TV conform to the standard bluetooth protocol, and have the disadvantages of long pairing time and incapability of automatic connection.
Therefore, the wearable Bluetooth headset with the automatically-connectable private protocol can pick up sound, so that the problem that near-field voice needs to be held by hands is solved, and the problems that the recognition distance of far-field voice cannot be far, the recognition directivity is poor, the recognition rate is low, and obvious pain points such as mistaken awakening are caused are solved. The user can use the Bluetooth headset to remotely control intelligent household equipment such as a TV and the like by voice; therefore, the existing far-speaking voice can be replaced, and the voice recognition accuracy is improved, so that the method is more natural. Therefore, the problem that near-field voice needs to be held by hands is avoided, and the problems that the recognition distance of far-field voice can not be far, the directivity is recognized, the recognition rate is low, false awakening exists and other obvious pain points are avoided. Importantly, automatic connection can be realized, the pairing connection period is short, and the connection is safer.
