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:

Format description

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

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

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

Basic AT Command

Please refer to the "AT instruction format" in the previous section for specific instructions and returned message formats.

In the introduction of the following instructions, duplicate formatting content will no longer be added, such as: /r/n
