2. AT COMMANDS

The Telit wireless module family can be controlled via the serial interface using the standard AT commands1F1F1. The Telit wireless module family is compliant with:

1. Hayes standard AT command set, 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)

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.

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 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 based on the recommended default setting of the sub parameter.

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:

- 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 function of the equipment, which generally involves more than the simple storage of a value for later use

• "tested" to determine:

o if sub parameters are associated with the action, the ranges of sub parameters values that

are supported; if the command has no sub parameters, issuing the correspondent Test command (trailing =?) raises the result code "ERROR". Note: issuing the Read command (trailing?) causes the command to be executed.

o 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

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.

Page 10

LWM2M AT Commands Reference Guide (ME910C1/NE910C1/ML865C1)

80529ST10974A Rev. 3 Page 10 of 54 2020-04-21

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.

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 are optional, issuing AT+CMD=<CR> causes the OK result code to be returned and the previous values of the omitted sub parameters to be retained.

2.2.1. String Type Parameters

A string, either enclosed between quotes or not, is 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 descriptions.

2.2.2. 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 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 "+"2F2F2). 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.

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

Page 11

LWM2M AT Commands Reference Guide (ME910C1/NE910C1/ML865C1)

80529ST10974A Rev. 3 Page 11 of 54 2020-04-21

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 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>.

The command line buffer accepts a maximum of 400 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR.

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

2.2.2.3. Carriage Returns, Line Feeds and Log

Generally, the number of carriage returns <CR> and line feeds <LF> at the end of command responses may vary. This scenario may also vary from software version to software version. We do not have evidence of this behavior in URC lines.

Command responses examples:

AT#LWM2MMON?<CR> <CR><LF> #LWM2MMON: "4"<LF>#LWM2MMON: "3" missing <CR> <CR><LF> <CR><LF> OK <CR><LF> AT#LWM2MFYACKURI=0,2<CR> <CR><LF> #LWM2MNFYACKURI: "/3/0/9"<LF>#LWM2MNFYACKURI: "/3/0/8" missing <CR> <CR><LF> <CR><LF> OK <CR><LF>

The user must be aware of this aspect before writing a script to parse the commands lines and the relative responses lines to generate a log.

2.2.3. 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? <CR><LF>+CMD1:2,1,10<CR><LF>

• information response to +CMD1=? <CR><LF>+CMD1(0-2),(0,1),(0-15)<CR><LF>

• 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

CONNECT 24004

CONNECT 48004

CONNECT 96004

CONNECT 144004

CONNECT 1200/754

2.2.4. 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.

2.2.5. 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.

Storage

2.3.1. Factory Profile and User Profiles

The Telit wireless modules store the values, set by several commands, in the internal nonvolatile 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 current 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, #SKTSAV, #ESAV); all these values are read at power-up.

In this document, each AT command description begins with a "AT Command short overview table" having the following format:

SIM Presence

Setting saved

Can be

aborted

MAX timeout

SELINT

see below

This chapter focus on the values that Setting saved field can assume and their meaning. The meaning of the other fields will be described in the next chapter. Setting saved field can have one of the value listed below

(to have information on the AT instance introduced hereafter, see the reference section of the #PORTCFG command):

Specific profile the parameters values set by the command are stored in the profile base section. The

stored values set is associated to the specific AT instance used to enter the command. It is a profile used by the specific AT instances.

Examples of the AT commands: +IPR, E, Q, V, X, &Y, etc. The parameters values set by the command are stored in the profile extended section.

The stored values set is associated to the specific AT instance used to enter the command. It is a profile used by the specific AT instance.

Examples of the AT commands: +FCLASS, +CREG, +CLIP, #STIA, etc.

Common profile the parameters values set by the command are stored in the profile extended section.

The stored values set is not associated to the specific AT instance used to enter the command. It is a profile shared between the AT instances.

Examples of the AT commands: +CALM, #E2SLRI, #DVI, etc.

Auto the parameters values set by the command are automatically stored in NVM, without

issuing any storing AT command, and independently from the profile (unique values). The values are automatically restored at startup.

AT commands examples: +COPS, +CGQREQ, #SCFG, etc. In some cases, the parameters values are store in the file system. AT commands examples: #TEMPCFG, #TEMPMON, etc.

Other the parameters values set by the command are stored in NVM issuing a specific

command and independently from the profile. Examples of the AT commands: #SLED setting is saved by #SLEDSAV

#BIQUADINEX setting is saved by #PSAV etc.

AT Command Short Overview Table

As stated before, each AT command description begins with a "AT Command short overview table" having the following format:

SIM Presence

Setting saved

Can be

aborted

MAX timeout

SELINT

Not required

No - 2

Here are the table fields meanings:

SIM Presence indicates if the AT command to be executed needs the SIM presence. Can be aborted indicates if the AT command can be aborted during its execution. MAX timeout indicates the time within which the command must be executed. SELINT indicates on which AT interface type the AT command is available.

In case the LwM2M client is enabled with the <mode> active, the <enabledStatus> parameter in #LWM2MSTS command reports the LwM2M as active just after the command insertion and while waiting for the #LWM2MACK confirmation.

In case the LwM2M client is enabled with the <mode> active, after the #LWM2MENA command insertion to disable it, the <enabledStatus> parameter returned by #LWM2MSTS command reports the LwM2M as active since the disabling message towards the server needs the #LWM2MACK confirmation; this happens only when the disabling command is typed out of the LwM2M client active time window (i.e.: outside the <guardReleaseTime> inserted in #LWM2MENA command).

In case the LwM2M client is enabled with the <mode> not active, after the #LWM2MENA command insertion to disable it, for a short period of time, the

Please notice that the URC reporting "FORCE_EXIT" <event> are always displayed, even in case of inactive service or in case of non-Telit clients.

During the PDP activation or deactivation triggered by the #LWM2MENA command, the client shall not manage any other #LWM2M commands for a short period of time.

If the client LwM2M is already enabled, a further enabling attempt will return an error.

AT#LWM2MENA?

If the client is enabled, read command reports the current values of parameters in the format:

#LWM2MENA: <en>,<pdpId>,<mode>,<guardRequestTime>,<guardReleaseTime>, <enabledStatus>

If the client is not enabled, read command reports the current values of parameters in the format:

#LWM2MENA: 0

The <enabledStatus> parameter reports the same values reported by the

#LWM2MSTAT. Therefore, for a list of the <enabledStatus> values, please refer to #LWM2MSTAT command.

In case the LwM2M client is enabled with the <mode> active, the <enabledStatus> parameter in read command reports the LwM2M as active just after the

command insertion and while waiting for the #LWM2MACK confirmation.

In case the LwM2M client is enabled with the <mode> active, after the #LWM2MENA command to disable it, the <enabledStatus> parameter in read command reports the LwM2M as active since the disabling message towards the server needs the #LWM2MACK confirmation; this happens only when the disabling command is typed out of the LwM2M client active time window (i.e.: outside the <guardReleaseTime> inserted in #LWM2MENA command).
