AT command set as follows:
1, Test communication
- Send: AT (return OK, A seconds press once again)
- Return: OK
2, Change Bluetooth serial interface communication baud rate
- Send: AT + BAUD1
- Return: OK1200
- Send: AT + BAUD2
- Return: OK2400
- 1---------1200
- 2---------2400
- 3---------4800
- 4---------9600
- 5---------19200
- 6---------38400
- 7---------57600
- 8---------115200
- 9---------230400
- A---------460800
- B---------921600
- C---------1382400
- 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.
