2. AT COMMANDS
The Telit wireless module family can be controlled via the serial interface using the standard AT commands1F1F
1
.
The Telit wireless module family is compliant with:
1. Hayes standard AT command set, 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.
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 recognized 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 sub parameter 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 sub parameter 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 sub parameters, and so have not a Read
command, which are called action type commands, action should be done based on the
recommended default setting of the sub parameter.
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 sub parameters; they also have a Read command (trailing?) to check the current values of sub
parameters.
- Action type commands. This type of command may be "executed" or "tested".
• "executed" to invoke a function of the equipment, which generally involves more than the simple
storage of a value for later use
• "tested" to determine:
o if sub parameters are associated with the action, the ranges of sub parameters values that
are supported; if the command has no sub parameters, issuing the correspondent Test
command (trailing =?) raises the result code "ERROR".
Note: issuing the Read command (trailing?) causes the command to be executed.
o 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 sub
1
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 combined with other parameters can be set up in the communications package
or typed in manually as a command line instruction.
