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.
