Problems solved by technology
The master device can choose which slave device to access, but it is difficult for a slave device to be connected to more than one master device
If there are second or more master devices in the application scene, when the first master device has an accident, other master devices need to manually pair with all Bluetooth slave devices one by one, which is extremely inconvenient to use and operate

Embodiment Construction
[0026] Such as figure 1 , is the bluetooth pairing method invented, the frame diagram of all bluetooth devices working normally, wherein ① is the main bluetooth device, ② is the automatic authorization protocol from the bluetooth device, ③ is the pairing link map from the bluetooth device, ④ / ⑤ / ⑥ are All the slave Bluetooth devices that have successfully paired with the master Bluetooth device 1, ⑦ the master Bluetooth device 2, and ⑩ the communication channel established between the master Bluetooth device 1 and the master Bluetooth device 2.
[0027] The bluetooth pairing system used in the present invention runs in the master bluetooth device one, and uses the bluetooth pairing system to draw a slave bluetooth device pairing link map drawn by the master bluetooth device one. The data packet is packaged with the bluetooth device automatic authorization protocol and encapsulated on the link map, and the communication channel is established between the master bluetooth device 1...

A Bluetooth device matching system is provided. A first master Bluetooth device draws all slave Bluetooth device link maps which are successfully matched with the device itself, and packets automatic authorization protocols of all the slave Bluetooth devices in matched link maps. Communication links are established between a second master Bluetooth device and the first master Bluetooth device. The second master Bluetooth device receives the matched link maps and the package protocols of the first master Bluetooth device. The second master Bluetooth device sends a heartbeat request to the first master Bluetooth device, and determines that the first master Bluetooth device runs abnormally if not being able to receive heartbeat return data within a preset period of time. The second Bluetooth device de-packages the automatic authorization protocols in the matched link maps received from the first master Bluetooth device, and makes a matching request and actively matches all the slave Bluetooth devices in the matched link maps. The second master Bluetooth device matches new matched link maps and work modes of all the slave Bluetooth devices.
Description
technical field [0001] The invention belongs to the technical field of short-distance communication, in particular to a bluetooth device pairing system. Background technique [0002] There are two common ways to pair Bluetooth devices, one is the pairing method without a password, and the other is the method that requires a password to do a random operation based on the current Bluetooth clock, address code and other information, and a random number is generated by the host , let the slave end input. [0003] There are several improved versions of the second way: [0004] Version 1: The random number is first input by the user on the host side, and then the same number is input from the slave side; [0005] Version 2: The host side fixes the random number to 0000 or 1234, and the slave side manually enters 0000 or 1234; [0006] Version 3: The fixed random number on the host side is 0000 or 1234. The slave side has entered the pairing mode, and it will automatically enter...
