The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a flowchart of a bluetooth pairing method of the present invention. It should be noted that the method of the present invention is not limited to the flow sequence shown in fig. 1 if the results are substantially the same. FIG. 2 is an interaction process diagram of the Bluetooth pairing method shown in FIG. 1
As shown in fig. 1 and 2, the method includes the following steps:
step S1, the Bluetooth peripheral sends a first data packet to the Bluetooth host through the low power consumption Bluetooth broadcast, and the first data packet includes the check information.
The bluetooth technology is a radio technology supporting short-distance communication of devices, and can perform wireless information interaction among various wireless terminal devices including smart phones, Personal Digital Assistants (PDAs), notebook computers, tablet computers, wireless earphones, wireless sound boxes and the like.
The wireless communication protocol between the Bluetooth host and the Bluetooth peripheral includes Bluetooth Low Energy (BLE) and classic Bluetooth enhanced data (BR/EDR). When the data volume transmitted between the Bluetooth host and the Bluetooth peripheral is large, data, such as voice information, is transmitted between the Bluetooth host and the Bluetooth peripheral through classical Bluetooth broadcasting.
The Bluetooth host can be a smart phone, a palm computer, a notebook computer, a tablet computer and the like, and the Bluetooth peripheral can be equipment with a Bluetooth function, such as a Bluetooth earphone, a Bluetooth sound box, smart glasses, a smart watch and the like. In the embodiment shown in fig. 2, the bluetooth host is exemplified by a handset having a bluetooth module, and the bluetooth peripheral is exemplified by a bluetooth headset.
Before this step, it can be understood that the bluetooth peripheral is first powered on, where powering on refers to turning on the power supply of the bluetooth peripheral, and usually the power supply is turned on by pressing the power on key of the bluetooth peripheral. The first data packet comprises address information of the low-power-consumption Bluetooth of the Bluetooth peripheral, name information of the low-power-consumption Bluetooth and verification information, wherein the verification information can be used for verifying whether the Bluetooth peripheral is the Bluetooth peripheral meeting preset conditions, and only when the Bluetooth peripheral meets the preset conditions, the Bluetooth host calls the connection interface of the classic Bluetooth to send a connection request to the Bluetooth peripheral. In this step, it may be set that the bluetooth peripheral sends the first data packet to the bluetooth host through a low-power bluetooth broadcast within a preset time (for example, the preset time is 1 minute) after the bluetooth peripheral is powered on; when the preset time is exceeded and no Bluetooth host computer receives the broadcasted first data packet, the Bluetooth peripheral can be automatically powered off or in a dormant state, and when the Bluetooth peripheral is powered on again or is awakened by pressing a key such as a switch and volume on the Bluetooth peripheral once, the Bluetooth peripheral sends the first data packet to the Bluetooth host computer again through the low-power Bluetooth broadcast.
In step S2, the bluetooth host receives the first packet and sends a request message to the bluetooth peripheral device via bluetooth low energy broadcasting.
The Bluetooth host comprises a touch display screen, and the touch display screen can be used for sensing touch operation of a user and outputting characters, pictures or videos.
In this step, when the bluetooth host receives the first data packet of the bluetooth peripheral, the touch display screen of the bluetooth host displays the name of the bluetooth peripheral. In this embodiment, the name of the bluetooth peripheral is the same as the name of the bluetooth low energy of the bluetooth peripheral, that is, the name of the bluetooth low energy of the bluetooth peripheral is displayed by the bluetooth host. It should be noted that, when the bluetooth host receives the first data packet sent by the bluetooth peripheral, the name of the bluetooth peripheral corresponding to the first data packet is displayed on the touch display screen, and the bluetooth host can receive a plurality of first data packets, so as to display a plurality of names of the bluetooth peripheral.
The Bluetooth host receives user input information and sends request information to the Bluetooth peripheral equipment according to the input information.
In this embodiment, the user input information refers to a click operation of clicking and selecting a target bluetooth peripheral name among a plurality of bluetooth peripheral names displayed on a touch display screen of the bluetooth host, and after the user completes the click operation, the bluetooth host responds to the click operation of the user and sends request information to a target bluetooth peripheral corresponding to the target bluetooth peripheral name through low power consumption bluetooth broadcasting. The request information is used for requesting the target Bluetooth peripheral to send a second data packet to the Bluetooth host. It will be appreciated that, as shown in fig. 2, the bluetooth host may start the bluetooth function and start to automatically search for the bluetooth peripheral before the bluetooth host receives the user's input information.
And step S3, the Bluetooth peripheral receives the request information sent by the Bluetooth host and sends a second data packet to the Bluetooth host through the low-power Bluetooth broadcast according to the request information.
The Bluetooth peripheral equipment is target Bluetooth peripheral equipment which receives the request information, and the second data packet comprises address information of classic Bluetooth and name information of classic Bluetooth. The name of the classic bluetooth of the bluetooth peripheral device corresponds to the name of the low-power-consumption bluetooth of the bluetooth peripheral device one by one, but is not displayed on the touch display screen of the bluetooth host.
In other embodiments, the name of the bluetooth peripheral is the same as the name of the classic bluetooth of the bluetooth peripheral, i.e. the bluetooth host displays the name of the classic bluetooth of the bluetooth peripheral. The name of the low-power-consumption Bluetooth of the Bluetooth peripheral corresponds to the name of the classic Bluetooth of the Bluetooth peripheral one by one, but is not displayed on the touch display screen of the Bluetooth host.
Step S4, the bluetooth host receives the second data packet and splices the first data packet and the second data packet into a target verification data packet.
Specifically, the bluetooth host splices the field occupied by the first data packet and the field occupied by the second data packet into a completed field. For example, the field occupied by the first packet is "00001", the field occupied by the second packet is "00010", and the field occupied by the second packet is "0000100010" after concatenation.
It should be noted that the spliced first data packet and the second data packet are data packets sent by the same bluetooth peripheral, and the combination of the first data packet and the second data packet is used for marking the target bluetooth peripheral.
And step S5, the Bluetooth host checks the target check data packet.
Specifically, the bluetooth host checks the checking information of the first data packet in the spliced target checking data packet. During product development, some bytes in a field occupied by a first data packet sent by the bluetooth peripheral device may be agreed to be a check flag bit and an agreed preset flag bit in advance, for example, the field occupied by the first data packet is "00001", and if the first byte and the second byte of the field occupied by the first data packet are agreed to be the check flag bit and the preset flag bit is "00", the check information is correct. For example, the field occupied by the first data packet is "01001", and if the first byte and the second byte of the field occupied by the first data packet are defined as the flag bits for checking and the preset flag bit is "00", the check information is incorrect.
And step S6, if the verification information corresponding to the target verification data packet is correct, the Bluetooth host calls the connection interface of the classic Bluetooth of the Bluetooth host according to the target verification data packet so as to initiate a connection request to the connection interface of the classic Bluetooth of the Bluetooth peripheral.
In this step, when the verification information is verified correctly, the bluetooth host calls the connection interface of the classic bluetooth to initiate a connection request to the connection interface of the classic bluetooth of the bluetooth peripheral according to the target verification data packet.
In the embodiment, the searching and pairing processes of the Bluetooth peripheral and the Bluetooth host are all data transmission through low-power-consumption Bluetooth, and classic Bluetooth information is sent in two data packets, so that on one hand, the data load can be reduced, and the safety performance is also improved; on the other hand, the Bluetooth external device starts to broadcast the first data packet through low power consumption after being started, and compared with the prior art, the Bluetooth external device is simpler to operate.
After the step S6, the method further includes a step S7, when the bluetooth peripheral and the bluetooth host are successfully paired and transmit data to each other through classic bluetooth, the bluetooth peripheral stops transmitting the first packet data to the bluetooth host through low power bluetooth broadcast.
After the Bluetooth peripheral equipment is successfully paired with the Bluetooth host, in order to reduce power consumption, the Bluetooth peripheral equipment stops sending the first packet of data to the Bluetooth host through low-power-consumption Bluetooth broadcasting.
Please refer to fig. 3, which is a sub-flowchart of step S4. The bluetooth host receives the second data packet and splices first data packet and second data packet into the target check-up data packet, specifically includes:
in step S41, the second packet is received.
Step S42, the concatenation order of the first data packet and the second data packet is set.
The splicing sequence of the first data packet and the second data packet comprises that the field occupied by the second data packet is spliced behind the field occupied by the first data packet and the field occupied by the second data packet is spliced in front of the field occupied by the first data packet.
And step S43, splicing the first data packet and the second data packet into a target verification data packet according to the splicing sequence.
