AT command
Default:
Slave, 9600 baud rate, N, 8, 1. Pincode 1234
AT command:
1. Communications Test:
Sent : AT
receive : OK
2. Change baud rate:
Sent : AT+BAUD1
receive : OK1200
Sent : AT+BAUD2
receive : OK2400
1---------1200
2---------2400
3---------4800
4---------9600
5---------19200
6---------38400
7---------57600
8---------115200
Baud rate setting can be save even power down.
3. Change Bluetooth device name:
Sent : AT+NAMEdevicename
receive : OKname
(devicename is the name you want the device to be , and it will be searched with this name)
Name setting can be save even power down.
4. Change Pincode:
Sent : AT+PINxxxx
receive : OKsetpin
(xxxx is the pin code you set)
Pin code can be save even power down.
