1. INTRODUCTION
Scope
This document covers the more significant standard and proprietary AT commands provided by
Telit's modules. Several module features are described and for each one of them the related AT
commands are explained through examples. This document is not an exhaustive description of
the AT commands implemented on the Telit's modules series, its target is only to give you an
entry point to the AT commands world.
Audience
The present User Guide is addressed to users that need to learn and use quickly standard and
proprietary AT commands. The reader can learn the use of the AT commands through simple
examples shown in the document, and then deepen the interested AT commands reading the
documents [1]/[17] in accordance with the used module.

2. SYNTAX
1.1. AT Command Syntax
The “AT” or “at” prefix must be set at the beginning of each command line. To terminate command line
enter
<CR>.Commands are usually followed by are sponse that includes “<CR> <LF> <response> <CR>
<LF>”. Throughout this document, only there sponses are presented <CR> <LF> are omitted in
tentionally.
Table 1.4: Types of AT command sand responses
AT command type
Syntax
Function
Test command
AT+CXXX=?
The mobile equipment returns the list of parameter sand
value ranges set with the corresponding Write command or
by internal processes.
Read command
AT+CXXX?
This command returns the currently set value of the
parameter or parameters.
Write command
AT+CXXX=<…>
This command sets user-definable parameter values.
Exec (ution)
command
AT+CXXX
The execution command reads non-variable parameters
deter-mined by internal processes in the UE.

3. BASIC COMMANDS
3.1. Repeat Previous Command Line: A/
Repeat Previous AT command line.
In general, after beginning a command line with character “a” or “A” a second character “t”, “T” or “/” has to
follow. “/”acts as line terminate character. In case of using a wrong second character, it is necessary to start
again with character “a” or “A”

ATS32?
32
OK
In this point, the AT command line terminator has become a
space instead of the previous carriage return
