1General Description

1.1 Description of AT Commands

ME3000_V2 provides AT command interfaces, through which the module could

communicate with the external devices conveniently. The AT commands set provided by

ME3000_V2 module not only covers the standard GSM voice call and SMS applications, but

adds some other commands based on GSM specification and some ZTE exclusive

commands for users to use conveniently.

1.1.1 Type of AT Commands

As a standard interface, the returned values and formats of AT commands are both fixed. As

a whole, the AT commands could be divided into four types:

Non-parameter commands: a type of simple commands with the format of

AT[+|&]<command>,e.g.: AT+CSQ, AT&W

Query commands: used to inquire the current setting value with the format of

AT[+|&]<command>?, e.g.: AT+CNMI?

Help commands: used to list the possible parameters of the command with the format of

AT[+|&]<command>=?, e.g.: AT+CMGL=?

Parameter commands: normally used format which provides strong flexibility with the

format of AT[+|&]<command>=<par1>,<par2>,<par3>…

The returned values of this type of commands are all the same. This will be clarified in details

later. The basic frame format of the returned value is:

<CR><LF><OK/ERROR>[ERROR INFO]<CR><LF>

1.1.2 Returned Format of AT Commands

The following describes the AT commands and returned descriptions supported by

ME3000_V2 module:

AT command returned format:

--<CR><LF><corresponding strings ><CR><LF>

--An exceptional case: e.g.: AT+ZPOWEROFF, directly return with “OK”

AT command status report (OK, ERROR):

--If there is error in AT command format, return with “ERROR”;

--If AT command executes successfully, return with “OK”;

1.1.3 AT Command Format

AT command starts with “AT” and ends with <CR>;

After the module runs, the serial port default setting will be: 8-digit data bit, 1-digit stop bit,
