Embodiment 1
[0029] Such as figure 2 As shown, after the main earphone is turned off unexpectedly, the Bluetooth device detects that the Bluetooth connection between it and the main earphone is unexpectedly disconnected and then switches to the search state, and the slave earphone detects that the TWS connection between it and the main earphone is unexpectedly disconnected and then switches to the search state. In the connectable state, if the Bluetooth device searches for the slave headset, the Bluetooth device will directly establish a Bluetooth connection with the slave headset, and at this time the slave headset will switch to the functional state of the master headset. In this way, after the master earphone is turned off unexpectedly, the bluetooth device and the slave earphone can quickly establish a bluetooth connection between them by actively switching their states.
Embodiment 2
[0031] Such as image 3 As shown in , the master earphone detects that the connection between it and the bluetooth device is about to be disconnected unexpectedly (for example, the master earphone is not shut down normally because the battery is dead), the master earphone sends a search signal to the bluetooth device on the one hand, and sends a search signal to the slave earphone on the other hand. Send the switch state signal, the Bluetooth device switches to the search state according to the received search signal, and the slave headset switches to the connectable state according to the received switch state signal. If the Bluetooth device searches the slave headset, the Bluetooth device and the slave headset directly Establish a Bluetooth connection, at this time switch from the function of the headset to the function of the main headset. In this way, before the main earphone is turned off abnormally, the main earphone actively sends signals to the Bluetooth device and the...
