# AT Command Detail

This article will describe in detail the grammatical format, function and use of each AT command. If not specified, an command only applies to Wi-Fi mode.

All command are effective immediately without special command to save, AT command can be input through serial debugging programs such as super terminals, or through programming.

#AT command format

AT+ command adopts the command line based on ASCII code in the following format:

#1\. Format description

  • a) <>: Represents the parts that must be included
  • b) []: Represents the optional part

#2\. Command format

AT+<CMD>[op][para-1, para-2, para-3,...]\r

  • a) AT+: Command message prefix

  • b) CMD: command string

  • c) [op]: command operator. It can be:

    1. "=": Represents parameter settings, or queries for specified parameters
    2. "?": Represents query system parameters
    3. None': Indicates the execution of command
    4. "=?": Indicates the parameters set by the query user

  • d) [para-n]: Represents the set parameter value or the specified query parameter

  • e) r: Entry terminator, ASCII code 0x0D

#3\. Response message format

[\r\n][+CMD:] [para-1, para-2, para-3,...]<\r\n><STATUS><\r\n>

  • a) r: Entry terminator, ASCII code: 0x0D

  • b) n: newline character, ASCII code: 0x0a

  • c) [+CMD:] Corresponding command string

  • d) [para-n] : Parameters returned at query time

  • e) [STATUS] There are two cases of successful execution of command:

    • (1) OK: means correct execution;
    • (2) ERROR: Represents an execution error.

#EVENT format

EVENT message describes the current Wi-Fi/BT function and network connection status, such as STA, AP connection status, TCP, UDP connection status, RFCOMM connection status, etc.

Event message format: \r\n+<TYPE>：[para-1,para-2,para-2,...,para-n]\r\n

  • <TYPE>: Event types include WEVENT, which means WiFi function notification, CIPEVENT, which means network connection notification, and `BTEVENT', which means connection notification of BT/RFCOMM (only supported by EMW3239).
  • [para-n]: Event parameters, see [EVENT Event Message] (# Event Event Message)
  • \r: carriage return, ASCII code 0x0D
  • \n: Line break, ASCII code 0x0a
