AT Commands:
Enter the AT command methods: power on the module ,
it is the AT model when not matching.
Interval of 1 second to send the AT command.
Default parameter: 9600, n,8,1 baud rate,
password is 1234
(1)Test communication
Send:AT (Interval of 1 second to send it)
Return:OK
(2)Change the baud of D200 module
Send:AT+RAUD1
Return:OK1200
Send:AT+RAUD2
Return:OK2400
..........
1------1200
2------2400
3------4800
4------9600(Default)
5------19200
6------38400
7------57600
8------115200
After using the AT command to set baud rate,
it will auto save them, don’t need to set it again.
(3)Change the name of bluetooth
Send:AT+NAMEname
Return:OKname
Name: new name, length<20 ascii
Eg.:Send AT+NAMEbill_gates
Return:OKname
Then the new name is bill_gates
(4)Change the password for matches
Send :AT+PINxxxx
Return:OKsetpin
Xxxx: it is the new password
(5)Change Master-slave mode
Send: AT+ROLE=M (setting module is Master)
Returns: OK+ROLE:M
Send: AT+ROLE=S (set the module is Slave ,
Default is Master)
Returns: OK+ROLE:S
(6)Set without checking
AT + PN (the default is this setting)
(7) Even parity check
AT + PE
(8)Odd parity check
AT + PO
