2. Overview

2.1. About the document

This document is to describe all AT commands implemented on the Telit wireless modules

listed on the Applicabilty Table.

NOTE:

Telit suggests all the system developers to use always the newer AT Commands Interface Style

defined by AT#SELINT=2; and in case you are starting a new design we highly recommend you

to use the newer AT Commands Interface Style defined by AT#SELINT=2 which gives you a

possibility to include all Telit’s new features and also all future implementations.

Moreover, Telit suggests to use the following settings to get the performance most customers are

looking for:

AT#SMSMODE=1

AT#REGMODE=1

3. AT COMMANDS

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

commands

. 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 GPRS specific commands.

3. 3GPP TS 27.005 specific AT commands for SMS (Short Message Service) and CBS

(Cell Broadcast Service)

4. FAX Class 1 compatible commands

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 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. 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.

3.2. AT Command Syntax

The syntax rules followed by Telit implementation of either Hayes AT commands, GSM

commands and FAX commands are very similar to those of standard basic and extended AT

commands. A special command (#SELINT, see §3.5.2.1.1) has been introduced in order to have

an AT interface very close to the standard one.

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 subparameters; they also have a Read

command (trailing ?) to check the current values of subparameters.

- 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:

(if the command #SELINT=0 or #SELINT=1 has been issued, see §3.5.2.1.1)

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.

(if the command #SELINT=2 has been issued, see §3.5.2.1.1)

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:

 (for #SELINT=0 or #SELINT=1 only)

An enhanced test command (trailing =??) has been introduced to maintain

backward compatibility for those commands whose subparameters changed the

range of possible values from version to version.

 (for #SELINT=2 only)

The response to the Test Command (trailing =?) may be changed in the future by

Telit to allow the description of new values/functionalities

 (for #SELINT=2 only)

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 be retained.

3.2.1. String Type Parameters

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).

When #SELINT=0 (or 1) mode is selected, a string not enclosed between quotes is changed in

upper case (e.g. mickey become MICKEY), while a string enclosed between quotes is case

sensitive.

When #SELINT=2 mode is selected, 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 descriptions.

3.2.2. Command Lines

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 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 subparameter 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 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 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.

3.2.2.1. ME Error Result Code - +CME ERROR: <err>

This is NOT a command, it is the error response to +Cxxx 3GPP TS 27.007 commands.

Syntax: +CME ERROR: <err>

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

Parameter: <err> - error code can be either numeric or verbose (see +CMEE).The

possible values of <err> are reported in the table:

3.2.3. Information Responses And Result Codes

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).

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

3.2.4. Command Response Time-Out

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 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.

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 dialling commands timing is referred to module registered on network

(“AT+CREG?” answer is “+CREG: 0,1” or “+CREG: 0,5”).

For Python commands, timing is referred to commands issued with module in idle, flash

memory not full and not fragmented, and after the first Python command. The first Python

command to be issued causes a system initialization that could last a couple of minutes. Baud

rate is fixed at 115200.

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.

During command mode, due to hardware limitations, under severe CPU load the serial port can

loose some characters if placed in autobauding at high speeds. Therefore if you encounter this

problem fix the baud rate with +IPR command.

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.

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, #PSAV and $GPSSAV); all of

these values are read at power-up.

The values set by following commands are stored in the profile base section; if #SELINT=2

they depend on the specific AT instance:

The values set by following commands are automatically stored in NVM, without issuing any

storing command and independently from the profile (unique values), and are automatically

restored at startup:

If #SELINT=2 they depend on the CMUX 0 instance only

It is partially stored in NVM, moreover only a part of it can depend on the specific CMUX instance; see command

description.

3.5.1. Command Line General Format

3.5.1.1. Command Line Prefixes

3.5.1.1.1. Starting A Command Line - AT

AT - Starting A Command Line

SELINT 0 / 1 / 2

The prefix AT, or at, is a two-character abbreviation (ATtention), always used to

start a command line to be sent from TE to TA, with the only exception of AT#/

prefix

Reference

3GPP TS 27.007

3.5.1.1.2. Last Command Automatic Repetition - A/

A/ - Last Command Automatic Repetition

SELINT 0 / 1 / 2

If the prefix A/ or a/ is issued, the MODULE immediately execute once again the

body of the preceding command line. No editing is possible and no termination

character is necessary. A command line may be repeated multiple times through

this mechanism, if desired.

If A/ is issued before any command line has been executed, the preceding command

line is assumed to have been empty (that results in an OK result code).

Note: this command works only at fixed IPR.

Note: the custom prefix AT#/ has been defined: it causes the last command to be

executed again too; but it doesn’t need a fixed IPR.

Reference

3.5.2.1. AT Interface Backward Compatibility

There are some slight modifications amongst the AT interfaces of Telit products. In order to

keep backward compatibility and on the same time to give the opportunity to the customer to get

competitor compatibility, Telit modules offer the specific command #SELINT to switch the

behaviour of the device and its AT command interface. It is up to the user to select the AT

interface he prefers.

The following table shows which AT commands interface can be applied and is default for the

specific product:

]]]

Parameters:

<mode> multiplexer transparency mechanism

0 - basic option; it is currently the only supported value.

0 - UIH frames used only; it is currently the only supported value.

<port_speed >

2 – 19200 bps

3 – 38400 bps

4 – 57600 bps

5 – 115200 bps

<N1> max frame size, it indicates the maximum lenght of the

information field of CMUX frame (point 5.7.2 of 3GPP TS

07.10)

1 to MaxFrameSize

Note: after entering the Multiplexed Mode an inactive timer of five

seconds starts. If no CMUX control channel is established before this

inactivity timer expires the engine returns to AT Command Mode

Note: CMUX cannot work with the automatic speed detection; the speed

must be set with AT+IPR=<rate> (before sending AT+CMUX) or using

the 3rd parameter <port_speed>.

If the <port_speed> parameter has been used, the speed will be changed

after the OK (response to AT+CMUX). At the end of the CMUX session

the IPR preserve the value set with <port_speed>.

To be sure that the firmware supports this feature, check it with the test

command.

Note: all the CMUX protocol parameters are fixed as defined in

GSM07.10 and cannot be changed. The parameter <N1> is not supported

by all products or software version; to be sure check it with the test

command. If <N1> is not supported or not used it will be set to the default

value.

Note: the default max frame size is: N1=127; using this configuration, the

largest allowed CMUX frame (including start and end flag) is 133 bytes

long.

Note: to set a N1 greater then 127, it is mandatory to configure the

module using the command AT#CPUMODE=3

AT+CMUX?

Note

There are situations in which the presentation of the URC controlled by +CREG is

slightly different from ETSI specifications: e.g. it is possible to have an excessive

presentation of the URC +CREG: 4. We identified this behaviour and decided to

maintain it as default for backward compatibility issues. It is indeed possible to

avoid it simply issuing AT#REGMODE=1 (see #REGMODE): this puts the

Operation Mode of Registration Status Commands in ‘Enhanced Registration

Operation Mode’ which is more formal.

+COPS - Operator Selection

SELINT 0 / 1

AT+COPS[=

[<mode>

[,<format>

[,<oper>]]]]

Set command forces an attempt to select and register the GSM network operator.

<mode> parameter defines whether the operator selection is done automatically or

it is forced by this command to operator <oper>.

The operator <oper> shall be given in format <format>.

The behaviour of +COPS command depends on the last #COPSMODE setting.

(#COPSMODE=0)

Parameters:

<mode>

0 - automatic choice (the parameter <oper> will be ignored) (factory default)

1 - manual choice unlocked (network is kept as long as available, then it can be

changed with some other suited networks to guarantee the service)

2 - deregister from GSM network; the MODULE is kept unregistered until a

+COPS with <mode>=0, 1, 4 or 5 is issued

3 - set only <format> parameter (the parameter <oper> will be ignored)

4 - manual/automatic (<oper> field shall be present); if manual selection fails,

automatic mode (<mode>=0) is entered

5 - manual choice locked (network is kept fixed, if the chosen network is not

available, then the mobile has no service)

+COPS - Operator Selection

SELINT 0 / 1

0 - alphanumeric long form (max length 16 digits)

1 - alphanumeric short form

2 - Numeric 5 or 6 digits [country code (3) + network code (2 or 3)]

<oper>: network operator in format defined by <format> parameter.

(#COPSMODE=1)

Parameters:

<mode>

0 - automatic choice (the parameter <oper> will be ignored) (default)

1 - manual choice (<oper> field shall be present)

2 - deregister from GSM network; the MODULE is kept unregistered until a

+COPS with <mode>=0, 1 or 4 is issued

3 - set only <format> parameter (the parameter <oper> will be ignored)

4 - manual/automatic (<oper> field shall be present); if manual selection fails,

automatic mode (<mode>=0) is entered

0 - alphanumeric long form (max length 16 digits)

2 - Numeric 5 or 6 digits [country code (3) + network code (2 or 3)]

<oper>: network operator in format defined by <format> parameter.

Note: <mode> parameter setting is stored in NVM and available at next reboot, if it

is not 3 (i.e.: set only <format> parameter).

Note: if <mode>=1 or 4 (or 5 if #COPSMODE=0), the selected network is stored

in NVM too and is available at next reboot (this will happen even with a new SIM

inserted)

Note: <format> parameter setting is never stored in NVM

Note: issuing AT+COPS<CR> is the same as issuing the Read command.

Note: issuing AT+COPS=<CR> is the same as issuing the command

AT+COPS=0<CR>.

AT+COPS?

Read command returns current value of <mode>,<format> and <oper> in format

<format>; if no operator is selected, <format> and <oper> are omitted

+COPS: <mode>[, <format>, <oper>]

AT+COPS=?

Test command returns a list of quadruplets, each representing an operator present in

the network.

+COPS - Operator Selection

SELINT 0 / 1

The behaviour of Test command depends on the last #COPSMODE setting.

(#COPSMODE=0)

The command outputs as many rows as the number of quadruplets, each of them in

the format:

+COPS: (<stat> ,<oper (in <format>=0)>,””,

<oper (in <format>=2)>)

where

<stat> - operator availability

0 - unknown

1 - available

2 - current

3 - forbidden

(#COPSMODE=1)

The quadruplets in the list are separated by commas:

+COPS: [list of supported (<stat> ,<oper (in <format>=0)>,,

<oper (in <format>=2)> )s][,,(list of supported <mode>s),

(list of supported<format>s)]

where

<stat> - operator availability

0 - unknown

1 - available

2 - current

3 - forbidden

Note: since with this command a network scan is done, this command may require

some seconds before the output is given.

Note: The value of parameter <oper> (in <format>=0) is the same as the former

GM862 family products.

+CLIP - Calling Line Identification Presentation

SELINT 0 / 1

AT+CLIP[=[<n>]]

Set command enables/disables the presentation of the CLI (Calling Line Identity) at

the TE. This command refers to the GSM supplementary service CLIP (Calling

Line Identification Presentation) that enables a called subscriber to get the CLI of

the calling party when receiving a mobile terminated call.

Parameters:

+CLIP - Calling Line Identification Presentation

SELINT 0 / 1

<n>

0 - disables CLI indication (factory default)

1 - enables CLI indication

If enabled the device reports after each RING the response:

+CLIP: <number>,<type>,””,128,<alpha>,<CLI_validity>

where:

<number> - string type phone number of format specified by <type>

<type> - type of address octet in integer format

128 - both the type of number and the numbering plan are unknown

129 - unknown type of number and ISDN/Telephony numbering plan

145 - international type of number and ISDN/Telephony numbering plan (contains

the character "+")

<alpha> - string type; alphanumeric representation of <number> corresponding to

the entry found in phonebook; used character set should be the one

selected with command Select TE character set +CSCS.

<CLI_validity>

0 - CLI valid

1 - CLI has been withheld by the originator.

2 - CLI is not available due to interworking problems or limitation or originating

network.

Note: in the +CLIP: response they are currently not reported either the subaddress

information (it’s always “” after the 2nd comma) and the subaddress type

information (it’s always 128 after the 3rd comma)

Note: issuing AT+CLIP<CR> is the same as issuing the Read command.

Note: issuing AT+CLIP=<CR> is the same as issuing the command

AT+CLIP=0<CR>.

selected with +CSCS.

<cli_validity>

0 - CLI valid

1 - CLI has been withheld by the originator

2 - CLI is not available due to interworking problems or limitations of originating

network

Note: if parameter <cmd> is omitted then network is not interrogated.

Note: in the query command the class parameter must not be issued.

Note: the difference between call waiting report disabling (AT+CCWA = 0,1,7)

and call waiting service disabling (AT+CCWA = 0,0,7) is that in the first case the

call waiting indication is sent to the device by network but this last one does not

report it to the DTE; instead in the second case the call waiting indication is not

generated by the network. Hence the device results busy to the third party in the

2nd case while in the 1st case a ringing indication is sent to the third party.

Note: The command AT+CCWA=1,0 has no effect a non sense and must not be

issued.

Note: issuing AT+CCWA<CR> is the same as issuing the Read command.

Note: issuing AT+CCWA=<CR> is the same as issuing the command

AT+CCWA=0<CR>.

AT+CCWA?

Read command reports the current value of the parameter <n>.
