This document is to describe all AT commands implemented on the Telit wireless module LE910-SKG.

LE910-SKG AT commands reference guide

80437ST10619A Rev.1 – 2014-09-16

The Telit wireless module family can be controlled via the serial interface using the standard AT commands1. 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.

LE910-SKG AT commands reference guide

80437ST10619A Rev.1 – 2014-09-16

The syntax rules followed by Telit implementation of either Hayes AT commands and GSM/WCDMA 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 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 sub parameters are associated with the action, the ranges of sub parameters values that are supported.

Action commands don’t store the values of any of their possible sub parameters.

In case of Telit command, “read” action may be used for the specific purpose.

Moreover:

The response to the Test Command (trailing =?) may be changed in the future by Telit to allow the description of new values/functionalities

If all the sub parameters 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 sub parameters to be retained.

A string, either enclosed between quotes or not, is considered to be 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 in 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 requires always writing the input string parameters within quotes: this is explicitly reported in the specific descriptions.

LE910-SKG AT commands reference guide

80437ST10619A Rev.1 – 2014-09-16

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 sub parameter  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

delimited with semicolon. In the second command the sub parameter is omitted.

 +CMD1?<CR> This is a Read command for checking current sub parameter values  +CMD1=?<CR> This is a test command for checking possible sub parameter

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 has been performed successfully, result code <CR><LF>OK<CR><LF> 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 <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 has been performed successfully, result code 0<CR> 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

The set of proprietary AT commands differentiates from the standard one because the name of

each of them begins with either “@”, “#”, “$” or “*”. Proprietary AT commands follow the same syntax rules as extended commands

LE910-SKG AT commands reference guide

80437ST10619A Rev.1 – 2014-09-16

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.

The TA response, in case of verbose response format enabled, for the previous examples command line could be as shown below:

 Information response to +CMD1?

 Information response to +CMD1=?

 Final result code <CR><LF>OK<CR><LF>

Moreover, there are other two types of result codes:  result codes that inform about progress of TA operation (e.g. connection establishment

CONNECT)

 Result codes that indicate occurrence of an event not directly associated with issuance of a

command from TE (e.g. ring indication RING).

Every command issued to the Telit modules returns a result response if response codes are enabled (default). The time needed to process the given command and return the response varies, depending on the command type. Commands that do not interact with the SIM or the network, and involve only internal set up settings or readings, have an immediate response, depending on SIM configuration (e.g., number of contacts stored in the phonebook, number of stored SMS), or on the network the command may interact with.

In the table below are listed only the commands whose interaction with the SIM or the network could lead to long response timings. When not otherwise specified, timing is referred to set command. For phonebook and SMS writing and reading related commands, timing is referred to commands issued after phonebook sorting is completed. For DTMF sending and dialing commands timing is referred to module registered on network (“AT+CREG?” answer is “+CREG: 0,1” or “+CREG: 0,5”).

The chain Command -> Response shall always be respected and a new command must not be issued before the module has terminated all the sending of its response result code (whatever it may be). This applies especially to applications that “sense” the OK text and therefore may send the next command before the complete code <CR><LF>OK<CR><LF> is sent by the module. It is advisable anyway to wait for at least 20ms between the end of the reception of the response and the issue of the next AT command. If the response codes are disabled and therefore the module does not report any response to the command, then at least the 20ms pause time shall be respected. During command mode, due to hardware limitations, under severe CPU load the serial port can lose some characters if placed in autobauding at high speeds. Therefore, if you encounter this problem fix the baud rate with +IPR command.

80437ST10619A Rev.1 – 2014-09-16

The Telit wireless modules stores the values set by several commands in the internal non volatile memory (NVM), allowing to remember this setting even after power off. In the NVM these values are set either as factory profile or as user profiles: there are two customizable user profiles and one factory profile in the NVM of the device: by default the device will start with user profile 0 equal to factory profile. For backward compatibility each profile is divided into two sections, one base section which was historically the one that was saved and restored in early releases of code, and the extended section which includes all the remaining values.

The &W command is used to save the actual values of both sections of profiles into the NVM user profile. Commands &Y and &P are both used to set the profile to be loaded at start up. &Y instructs the device to load at start up only the base section. &P instructs the device to load at start up the full profile: base + extended sections. The &F command resets to factory profile values only the command of the base section of profile, while the &F1 resets to factory profile values the full set of base + extended section commands.

The values set by other commands are stored in NVM outside the profile: some of them are stored always, without issuing any &W, some other are stored issuing specific commands (+CSAS, #SLEDSAV, #VAUXSAV, #SKTSAV, #ESAV); all of these values are read at power-up.

The values set by following commands are stored in the profile base section:

GSM DATA MODE : +CBST AUTOBAUD : +IPR COMMAND ECHO: E RESULT MESSAGES: Q VERBOSE MESSAGES: V EXTENDED MESSAGES: X FLOW CONTROL OPTIONS: &K, +IFC DSR (C107) OPTIONS: &S DTR (C108) OPTIONS: &D DCD (C109) OPTIONS : &C POWER SAVING: +CFUN DEFAULT PROFILE: &Y0 S REGISTERS: S0;S1;S3;S4;S5;S7;S10;S25;S38 CHARACTER FORMAT: +ICF

The values set by following commands are stored in the profile extended section:

+DR, +CSCS, +CREG, +CR, #NWEN, +CAOC

+CIND, +CMER, +CPBS,

+CMEE, +CEREG, +CMGF, +CSDH, +CNMI,

#VAUX Stored by #VAUXSAV command.

#USERID, #PASSW, #PKTSZ, #DSTO, #SKTTO, #SKTSET #SKTCT Stored by #SKTSAV command and automatically restored at startup; factory default values are restored by #SKTRST command.

#ESMTP, #EADDR, #EUSER, #EPASSW Stored by #ESAV command and automatically restored at startup; factory default values are restored by #ERST command.
