Command

Commands are control instructions actively sent by the host to the module; after receiving the commands, the module shall respond with <CR><LF>OK<CR><LF> as reply.

Command Format

AT+Command{=Param1{,Param2{,Param3...}}}<CR><LF>

All instructions start with AT and end with <CR><LF>
<CR> stands for carriage return, corresponding to HEX 0x0D
<LF> represents a newline character, corresponding to HEX 0x0A
If the instruction contains parameters, the parameters should be separated from the instruction using =
If the instruction contains multiple subparameters, the parameters should be separated by ,
If a response is returned, the response starts with <CR><LF> and ends with <CR><LF>
Module will always report command’s execution result by using OK for success or ERROR for failure

Example：Read the module Bluetooth name

Send: <<AT+NAME<CR><LF>
Response: >><CR><LF>+NAME=FSC-BT9101<CR><LF>
Response：>><CR><LF>OK<CR><LF>

Write an unsupported baud rate

Send: <<AT+BAUD=0<CR><LF>
Response: >><CR><LF>ERROR<CR><LF>
