AT COMMANDS
The Telit wireless module family can be controlled via the serial interface using the standard AT
commands1. The Telit wireless module family is compliant with:
1. Hayes standard AT command set, in order to maintain the compatibility with existing SW
programs.
2. 3GPP TS 27.007 specific AT command and GPRS specific commands.
3. 3GPP TS 27.005 specific AT commands for SMS (Short Message Service) and CBS (Cell
Broadcast Service)
Moreover Telit wireless module family supports also Telit proprietary AT commands for special
purposes.
The following is a description of how to use the AT commands with the Telit wireless module
family.
3.1. Definitions
The following syntactical definitions apply:
<CR> Carriage return character, is the command line and result code terminator character,
which value, in decimal ASCII between 0 and 255,is specified within parameter S3. The
default value is 13.
<LF> Linefeed character, is the character recognised as line feed character. Its value, in
decimal ASCII between 0 and 255, is specified within parameter S4. The default value is
10. The line feed character is output after carriage return character if verbose result codes
are used (V1 option used ) otherwise, if numeric format result codes are used (V0 option
used) it will not appear in the result codes.
<...> Name enclosed in angle brackets is a syntactical element. They do not appear in the
command line.
[...] Optional subparameter of a command or an optional part of TA information response is
enclosed in square brackets. Brackets themselves do not appear in the command line.
When subparameter is not given in AT commands which have a Read command, new
value equals to its previous value. In AT commands which do not store the values of any
of their subparameters, and so have not a Read command, which are called action type
commands, action should be done on the basis of the recommended default setting of the
subparameter.
1The AT is an ATTENTION command and is used as a prefix to other parameters in a string. The AT command combined
with other parameters can be set up in the communications package or typed in manually as a command line
instruction.combined with other parameters can be set up in the communications package or typed in manually as a
command line instruction.

3.2. AT Command Syntax
The syntax rules followed by Telit implementation of either Hayes AT commands, GSM
commands are very similar to those of standard basic and extended AT commands
There are two types of extended command:
-Parameter type commands. This type of commands may be “set” (to store a value or
values for later use), “read” (to determine the current value or values stored), or “tested”
(to determine ranges of values supported). Each of them has a test command (trailing =?)
to give information about the type of its subparameters; they also have a Read command
(trailing ?) to check the current values of subparameters.
-Action type commands. This type of command may be “executed” or “tested”.
•“executed“ to invoke a particular function of the equipment, which generally involves
more than the simple storage of a value for later use
•“tested” to determine:
if subparameters are associated with the action, the ranges of subparameters values that are
supported; if the command has no subparameters, issuing the correspondent Test command
(trailing =?) raises the result code “ERROR”.
Note: issuing the Read command (trailing ?) causes the command to be executed.
whether or not the equipment implements the Action Command (in this case issuing the
correspondent Test command - trailing =? - returns the OK result code), and, if
subparameters are associated with the action, the ranges of subparameters values that are
supported.
Action commands don’t store the values of any of their possible subparameters.
Moreover:
The response to the Test Command (trailing =?) may be changed in the future by Telit to
allow the description of new values/functionalities.
If all the subparameters of a parameter type command +CMD are optional, issuing
AT+CMD=<CR> causes the OK result code to be returned and the previous values of the
omitted subparameters to beretained.
3.2.1. String Type Parameters

Telit LE910 V2 Series AT Commands

A string, either enclosed between quotes or not, is considered to be a valid string type parameter
input. According to V25.ter space characters are ignored on the command line and may be used
freely for formatting purposes, unless they are embedded in numeric or quoted string constants;
therefore a string containing a space character has to be enclosed between quotes to be
considered a valid string type parameter (e.g. typing AT+COPS=1,0,”A1” is the same as typing
AT+COPS=1,0,A1; typing AT+COPS=1,0,”A BB” is different from typing AT+COPS=1,0,A
BB).
A string is always case sensitive.
A small set of commands requires always to write the input string parameters within quotes: this
is explicitly reported in the specific descriptions.
3.2.2. Command Lines
A command line is made up of three elements: the prefix, the body and the termination
character.
The command line prefix consists of the characters “AT” or “at”, or, to repeat the execution of
the previous command line, the characters “A/” or “a/” or AT#/ or at#/.
The termination character may be selected by a user option (parameter S3), the default being
<CR>.
The basic structures of the command line are:
•ATCMD1<CR> where AT is the command line prefix, CMD1 is the body of a basic
command (nb: the name of the command never begins with the character “+”) and <CR> is
the command line terminator character
•ATCMD2=10<CR> where 10 is a subparameter
•AT+CMD1;+CMD2=, ,10<CR> These are two examples of extended commands (nb: the
name of the command always begins with the character “+”2). They are delimited with
semicolon. In the second command the subparameter is omitted.
•+CMD1?<CR> This is a Read command for checking current subparameter values
•+CMD1=?<CR> This is a test command for checking possible subparameter values
These commands might be performed in a single command line as shown below:
ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=?<CR>
anyway it is always preferable to separate into different command lines the basic commands and
the extended commands; furthermore it is suggested to avoid placing several action commands in
2The set of proprietary AT commands differentiates from the standard one because the name of each of them begins with
either “@”, “#”, “$” or “*”. Proprietary AT commands follow the same syntax rules as extended commands
