Telit LE910 V2 Series AT Commands

AT COMMANDS

80446ST10707A Rev. 0– 2015-11-03

The Telit wireless module family can be controlled via the seria l in t er fa c e u si n g t he st a n da r d AT commands

. The Telit wireless module family is compliant with:

1. Hayes standard AT com mand se t, in order to maintain the com patibility with existi ng SW

programs.

2. 3GPP TS 27.007 specific AT command and GPRS specific commands.

3. 3GPP TS 27.005 specific AT commands for SMS (Sho rt Messag e 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.

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 be tween 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 an d 255, is speci fi ed w ithin parameter S4. The default value is

10. The line feed ch ara ct er i s ou tput after carriage return character if v erbo se re sul t code s 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 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, 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 subparameter.

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.

Telit LE910 V2 Series AT Commands

3.2. 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:

- Parame ter 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; t hey also have a Read command (trailing ?) to check the current values of subparameters.

- A ctio n ty pe c o mman d s. This type of command may be “executed” or “tested”.

80446ST10707A Rev. 0– 2015-11-03

• “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: if subparameters are associated with the action, the ranges of subparameters values that are supported; if the command has no subparameters, issuing the correspondent Test command (trailing =?) raises the result code “ERROR”. Note: issuing the Read command (trailing ?) causes the command to be executed.

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 don’t store the values of any of their possible subparameters.

Moreover:

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

If all the subparameters of a parameter type command +CMD are optional, issuing AT+CMD=<CR> causes the OK result code to be returned and the previous values of the omitted subparameters to beretained.

3.2.1. String Type Parameters

Mod. 0808 2011-07 Rev.2

Telit LE910 V2 Series AT Commands

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 string is always case sensitive.

A small set of commands requires always to write the input string parameters within quotes: this is explicitly reported in the specific desc ripti ons.

3.2.2. Command Lines

80446ST10707A Rev. 0– 2015-11-03

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/” or AT#/ or at#/. 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 “+”

). They are delimited with

semicolon. In the second command the subparameter is 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 av oid pl ac ing sev era l a ct ion com m an ds in

The set of proprietary AT c o mmands 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

The TA response, in case of verbose response form at enabled, for the prev ious examples comm and 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).

Here the basic result codes according to ITU-T V25Ter recommendation

<text> can be”300”, “1200”, “2400”, “4800”, “9600”, “14400” or “1200/75”

Telit LE910 V2 Series AT Commands

3.2.4. Command R esponse Time-Out

Every command issued to the Telit modu les returns a resul t respo nse, if re spons e 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 only involve internal setups or readings, have an immediate response.Commands that interact with the SIM or the network could take many seconds to send a 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.

3.2.5. Command Issuing Timing

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.

80446ST10707A Rev. 0– 2015-11-03

3.3. Storage

3.3.1. Factory Profile And User Profiles

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 startup. &Y instructs the device to load at startup only the base section . &P instructs the device to load at startup 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.

<rst> - reset flag 0 - do not reset the ME before setting it to <fun> functionality level 1 - reset the device. The device is fully functional after the reset. This value is available only for <fun> = 1

Note: issuing AT+CFUN=4[,0] actually causes the module to perform either a network deregistration and a SIM deactivation.

Note: if power saving enabled, it reduces the power consumption during the idle time, thus allowing a longer standby time with a given battery capacity.

Note: to place the module in power saving mode, set the <fun> parameter at value = 5 and the line DTR (RS232) must be set to OFF. Once in power saving, the CTS line switch to the OFF status to signal that the module is really in power saving condition. During the power saving condition, before sending any AT command on the serial line, the DTR must be set to ON (0V) to exit from power saving and it must be waited for the CTS (RS232) line to go in ON status. Until the DTR line is ON, the module will not return back in the power saving condition Note: the power saving function does not affect the network behaviour of the module, even during the power save condition the module remains registered on the

Note: in GSM, the received signal strength indication is the average of the received signal level measurement samples in dBm, taken on a channel within the reporting period of length one SACCH multi frame, and is mapped as above.

For UMTS, the current radio signal strength indicates CPICH RSCP in levels. According to the specification 3GPP TS25.133, the level range is from 0 to 91, with

0 less than (-115) dBm 1 (-115) dBm...(-114) dBm . . . 91 (-25) dBm or greater 99 - not known or not detectable

Values between -115dbm and -120dbm will all be represented by level 0 To be compliant with 3GPP TS27.007 specification, the above 0...91 levels are mapped to range 0...31:
