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
