AT Command Description

Specification Description

Applicable to the entire document

{} : Including content in {…} is optional
<< : COMMAND sent by the host to the module
>> : Module responds to the host’s RESPONSE/EVENT

Command

The command is a control instruction actively sent by the host to the module. After receiving the command, the module needs to reply with <CR><LF>OK<CR><LF> as an acknowledgment.

Command Format

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

All instructions start with AT，and end with <CR><LF>
<CR> represents carriage return, corresponding to HEX as 0x0D
<LF> represents a line break, corresponding to HEX as 0x0A
If the instruction contains parameters, the parameters should be separated by =
If the instruction contains multiple parameters, the parameters should be separated by ,
If the instruction returns a response, the response starts with <CR><LF>， ends with <CR><LF>
The module should always return the result of instruction execution (success returns OK，failure returns ERROR)

Example：Read module Bluetooth name

Send: <<AT+NAME<CR><LF>
Response: >><CR><LF>+NAME=FSC-BT2064<CR><LF>
Response：>><CR><LF>OK<CR><LF>

Write unsupported Baud rate

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