3 AT COMMANDS

The Telit wireless modules family can be controlled via the serial interface using the standard AT commands

1

.

The Telit wireless modules family is compliant with:

1. Hayes standard AT command set, in order to maintain the compatibility with existing SW programs.

2. ETSI GSM 07.07 specific AT command and GPRS specific commands.

3. ETSI GSM 07.05 specific AT commands for SMS (Short Message Service) and CBS (Cell Broadcast Service)

4. FAX Class 1 compatible commands

Moreover Telit wireless modules 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. It does 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 (called action type commands), and so don’t have a Read

command, action should be done on the basis of the recommended default setting of the subparameter.

3.2 AT Command Syntax

The syntax rules followed by Telit implementation of either Hayes AT commands or GSM/WCDMA

commands are very similar to those of standard basic and extended AT commands. There are two types of

extended command:

The 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.



- 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 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 do not store the values of any of their possible subparameters.

Moreover:

o The response to the Test Command (trailing =?) may be changed in the future by Telit to allow

the description of new values/functionalities

o If all the subparameters of a parameter type command +CMD (or #CMD or $CMD) are

optional, issuing AT+CMD=<CR> (or AT#CMD=<CR> or AT$CMD=<CR>) causes the OK

result code to be returned and the previous values of the omitted subparameters to be retained.

String Type Parameters

A string must be enclosed between quotes or it will not be considered as 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 on 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 small set of commands always requires writing the input string parameters within quotes. This is

explicitly reported in the specific descriptions.

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/”.

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 delimit with semicolon. In the second command, the subparameter 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 the same command line, because if

one of them fails, then an error message is received but it is not possible to argue which one of them has failed

the execution.

If command

V1 is enabled (verbose responses codes) and all commands in a command line have been

performed successfully, result code

<CR><LF>OK<CR><LF> is sent from the TA to the TE.

If subparameter values of a command are not accepted by the TA or command itself is invalid, or command

cannot be performed for some reason, result code

<CR><LF>ERROR<CR><LF> is sent and no

subsequent commands in the command line are processed.

If command

V0 is enabled (numeric responses codes) and all commands in a command line have been

performed successfully, result code

0<CR> is sent from the TA to the TE.

If sub-parameter values of a command are not accepted by the TA or command itself is invalid, or command

cannot be performed for some reason, result code

4<CR> and no subsequent commands in the command line

are processed.

In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR:

<err> or +CMS ERROR: <err>

.

NOTE: The command line buffer accepts a maximum of 80 characters. If this number is

exceeded none of the commands will be executed and TA returns ERROR.
