The Telit wireless module family can be controlled via the serial interface using the standard AT
commands
1
. 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 EPS 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.
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 on the basis of the recommended default setting
of the sub parameter.

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.
