Not recommended in more than 115200 baud rate, the signal interference will make the system not stability
3, change bluetooth name
Send: AT + NAMEname
Return: OKname
Parameter name: will set the current name, which was the name of the search to Bluetooth. Within 20 characters.
Example: send AT + NAME bill_gates
Back to OKname
now Bluetooth name is bill_gates
Parameters can power lost save, modify it only need once. The PAD service can see change Bluetooth name
4, Change Bluetooth pairing password
Send: AT + PINxxxx
Return: OKsetpin
Example: send AT + PIN8888
Back to OKsetpin
now Bluetooth pairing password is 8888, module's default password g is 1234.
Parameters can power lost save, modify it only need once.
