AT Commands
Users can use AT commands to setup the module with different configurations. Every AT command must be followed with <CR> and<LF> control character which is 0x0D and 0x0A in hexadecimal. Every AT command will followed with a response "OK". They will be some basic AT command you should know.
AT
AT command is use to test the module to see if it is OK.
AT+RESET
AT+RESET command is reset the module back to power up status.
AT+ROLE?
AT+ROLE? command inquiry the module's role, 0 = Slave, 1 = Master, 2 = Slave-loopback.
AT+ROLE=<param>
AT+ROLE command is used to set the module with master or slave, 0 = Slave, 1 = Master, 2 = Slave-loopback. You have to configure one module to master and the other to slave to become a pair.
AT+CMODE?
AT+CMODE? command inquiry the link mode. 0 = Specific bluetooth link address, 1 = Any bluetooth link address, 2 = Slave-loopback
AT+CMODE=<param>
AT+CMODE command is used to setup module link mode. 0 = Specific bluetooth link address, 1 = Any bluetooth link address, 2 = Slave-loopback. It is better to set the mode to 1 if you only have one pair device, because it is much easier to make them a pair.
AT+PSWD?
AT+PSWD? command inquiry the password of the module.
AT+PSWD=<param>
AT+PSWD command is used to set the pairing password.
AT+UART?
AT+UART? command inquiry the uart configurations.

Commands to change default configuration
1. Set working MODE
\r\n+STWMOD=0\r\n Set device working mode as client (slave). Save and Rest.
\r\n+STWMOD=1\r\n Set device working mode as server (master). Save and Rest.
Note: \r\n is necessary for operation and the value of are 0x0D 0x0A in Hex. \r and \n represent carriage-return and line-feed(or next line),
2.Set BAUDRATE
\r\n+STBD=115200\r\n Set baudrate 115200. Save and Rest.
Supported baudrate: 9600, 19200,38400,57600,115200,230400,460800.
3. Set Device NAME
\r\n+STNA=abcdefg Set device name as “abcdefg”. Save and Rest.
4. Auto-connect the last paired device on power
\r\n+STAUTO=0\r\n Auto-connect forbidden. Save and Rest.
\r\n+STAUTO=1\r\n Permit Auto-connect. Save and Rest.
5. Permit Paired device to connect me
\r\n+STOAUT=0\r\n Forbidden. Save and Rest.
\r\n+STOAUT=1\r\n Permit. Save and Rest.
6. Set PINCODE
\r\n +STPIN=2222\r\n Set pincode “2222”, Save and Rest.
7. Delete PINCODE(input PINCODE by MCU)
\r\n+DLPIN\r\n Delete pincode. Save and Rest.
8. Read local ADDRESS CODE
\r\n+RTADDR\r\n Return address of the device.
9. Auto-reconnecting when master device is beyond the valid range (slave device will auto-reconnect in 30 min when it is beyond the valid range)
\r\n+LOSSRECONN=0\r\n Forbid auto-reconnecting.
\r\n+LOSSRECONN=1\r\n Permit auto-reconnecting.
