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. <LF> Linefeed character is the character recognized as line feed character. <...> 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.

AT Command Syntax

The AT command format supported by Telit module is following the 3GPP related standards. There are two types of extended command:

- Parameter type commands. This type of commands may be:

• Set command, AT+CMD=[<value>]<CR>, to store a value or values for later use

• Read command, AT+CMD?<CR>, to determine the current value or values stored

• Test command, AT+CMD=?<CR>, to give information about the type of its subparameters

- Action type commands. Execution command, This type of command may be “executed” or “tested”

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.

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.

NOTE:

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.

2.2.1. 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/”. The termination character may be selected by a user option (parameter S3), the default being <CR>.

The basic structures of the command line are:

• AT command without parameter, AT is the command line prefix, CMD1 is the body of a basic command and <CR> is the command line terminator character, format: AT[＋

|&]<command> Example: AT+CGMR

• Read command for checking current sub-parameter values, Format: AT[＋ |&]<command>?

Example: AT+CMEE?

• Test command for checking possible sub-parameter values, Format: AT[＋ |&]<command>=?

Example: AT+CGDCONT=?

• AT command with parameter, Format: AT[＋|&]<command>=<par1>,<par2>,<par3>… The response of this command is:

• <CR><LF><response><CR><LF>

• <CR><LF><OK/ERROR>[ERROR information]<CR><LF>

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.

2.2.2. 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> 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

2.2.3. 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 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.

Command

Estimated maximum time to get

response (Seconds)

+COPS

180 (For test command)

+CLCK

180

+CPWD

180

+CPIN

+CRSM

2.2.4. 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 lose some characters if placed in auto-baud at high speeds. Therefore, if you encounter this problem fix the baud rate with +IPR command.

ATS12 Set Escape Code Guard Time

This command sets the escape code guard time in fiftieths of a second. The escape guard time is used to measure when to detect the +++ escape sequence has been entered by the PC in order to drop out of data mode back to AT command mode.

The guard time determines the time that forms a guard period before and after three escape sequence characters. In order to distinguish an escape sequence from just three escape sequence characters in the data stream there is timing associated to the three escape sequence characters of an escape sequence.

The time between the last byte of the data stream and the first escape sequence character must be at least the guard time and the time between each escape sequence character of the escape sequence must be less than the guard time and no other byte is received after the third escape sequence character for the time of the guard time. If an escape sequence is detected, the OK result code will be sent to the DTE. Otherwise, the DCE will stay in data mode.

ITU-T 3GPP TS 27.007 Note

• Set Escape Code Guard Time command

For example: “<Guard time>+++<Guard time>”

AT+CCIOTOPT CIoT Optimization Configuration

The set command controls which CIoT EPS optimizations the UE indicates as supported and preferred in the ATTACH REQUEST and TRACKING AREA UPDATE REQUEST messages. The command also allows reporting of the CIoT EPS optimizations that are supported by the network. A UE supporting CIoT functionality may support control plane CIoT EPS optimization or user plane CIoT EPS optimization or both (see 3GPP TS 24.301, sub-clause 9.9.3.34). Based on the application characteristics the UE may prefer to be registered for control plane CIoT EPS optimization or for user plane CIoT EPS optimization (see 3GPP TS 24.301, sub-clause 9.9.3.0B). Further the network may support control plane CIoT EPS optimization or user plane CIoT EPS optimization or both (see 3GPP TS 24.301, sub-clause 9.9.3.12A). The set command is used also to control the unsolicited result code +CCIOTOPTI. An unsolicited result code +CCIOTOPTI: <supported_Network_opt> is used to indicate the supported CIoT EPS optimizations by the network. The read command returns the current settings for supported and preferred CIoT EPS optimizations and the current status of unsolicited result code +CCIOTOPTI.

Execution command

AT+CCIOTOPT=[<n>,[<supported UE_opt>[,<preferred_UE_opt>]]]

AT+CCHO Open UICC Logical Channel

Execution of this command causes the MT to return <sessionid> to allow the TE to identify a channel that is being allocated by the currently selected UICC, which is attached to ME. The currently selected UICC will open a new logical channel; select the application identified by the <dfname> received with this command and return a session Id as the response. The ME restricts the communication between the TE and the UICC to this logical channel. This <sessionid> is used when sending commands with Generic UICC Logical Channel access +CGLA commands.

Execution command

AT+CCHO=<dfname>

Response

• <sessionid>

• OK

• If error is related to wrong AT syntax:

+CME ERROR: <err>

Parameters

• <dfname>: String type in hexadecimal character format. All selectable applications in the UICC

are referenced by a DF name coded on 1 to 16 bytes

• <sessionid>: integer type; a session Id to be used to target a specific application on the smart

card (e.g. (U)SIM, WIM, ISIM) using logical channels mechanism

• See 3GPP TS 31.101 for more information about defined values.

AT+CCHC Close UICC Logical Channel

This command asks the ME to close a communication session with the active UICC. The ME closes the previously opened logical channel. The TE will no longer be able to send commands on this logical channel. The UICC will close the logical channel when receiving this command.

Execution command

AT+CCHC=<sessionid>

Response

• CCHC

• OK

• If error is related to wrong AT syntax:

+CME ERROR: <err>

Parameters

• <sessionid>: integer type; the session used to target a specific application on the smart card

(e.g. (U)SIM, WIM, ISIM) using logical channels mechanism

• See 3GPP TS 31.101 for more information about defined values.

AT+CGLA Generic UICC Logical Channel Access

Set command transmits to the MT the <command> is sent as is to the selected UICC. The UICC <response> is sent back by the MT to the TA as is. This command allows a direct control of the currently selected UICC by a distant application on the TE. Although +CGLA allows the TE to take control over the UICC-MT interface, there are some functions of the UICC-MT interface that logically do not need to be accessed from outside the TA/MT and, for security reasons the GSM network authentication should not be handled outside the TA/MT. So, a Run GSM Algorithm command or an Authenticate command in GSM context shall not be allowed whether the +CGLA is locked or unlocked. However, the TE may send Authenticate commands in other security contexts (e.g. EAP security context).

Execution command

AT+CGLA=<sessionid>,<length>,<command>

Response

• +CGLA: <length>,<response>

• OK

• If error is related to wrong AT syntax:

+CME ERROR: <err>

Parameters

• <sessionid>: integer type; this is the identifier of the session used to send the APDU commands

to the UICC. It is mandatory to send commands to the UICC when targeting applications on the smart card using a logical channel other than the default channel (channel "0").

• <length> : integer type; length of the characters that are sent to TE in <command> or

<response> (two times the actual length of the command or response)

• <command> : command passed on by the MT to the UICC in the format as described in

3GPP TS 31.101 (hexadecimal character format)

• <response> : response to the command passed on by the UICC to the MT in the format as

described in 3GPP TS 31.101 (hexadecimal character format)

AT+CGACT PDP context activate or deactivate

The execution command is used to activate or deactivate the specified PDP context (s). After the command has completed, the UE remains in V.250 command state. If any PDP context is already in the requested state, the state for that context remains unchanged. If the UE is not PS attached when the activation form of the command is executed, the UE first performs a PS attach and them attempts to activate the specified contexts. Note that in the 27.007 specification there is the following statement:

• For EPS, if an attempt is made to disconnect the last PDN connection, then the UE responds with ERROR or, if

extended error responses are enabled, a +CME ERROR. This applies when use of CID0 is enabled for the PDN connection activated during attach (AT*MLTEGCF=2). In fact,

entering AT+CGACT=<0 or 1>,0 will generate ERROR response If CID0 mode is not enabled (AT*MLTEGCF=0/1) then it is possible to enter the AT+CGACT command to deactivate the last PDN connection from the point of view of the middleware. When the user uses AT+CGACT to disconnect the last PDN connection the following occurs:

• The PDN connection is preserved in the protocol stack

• The PDN connection is disconnected at the middleware, so the <cid> for the PDN connection is marked as

deactivated

• OK response is returned rather than ERROR

For EPS, the activation request for an EPS bearer resource will be answered by the network by either an EPS dedicated bearer activation or EPS bearer modification request. The request must be accepted by the UE before the PDP context can be set in to established state.

• If no <cid>s are specified the activation form of the command activates all defined contexts.

• If no <cid>s are specified the deactivation form of the command deactivates all active contexts.

The read command returns the current activation states for all the defined PDP contexts. The test command is used for requesting information on the supported PDP context activation states.

Set command AT+CGACT=[<state>[,<cid>[,<cid>[,…]]]] Response

• OK

• NO CARRIER

• ERROR

Parameter

• <state> indicates the state of PDP context activation 0 – deactivated 1 – activated Other values are reserved and will result in an ERROR response to the execution command.

• <cid> a numeric parameter which specifies a particular PDP context definition (see +CGDCONT command)

AT+CGDEL Delete Non-Active PDP Contexts

The execution command +CGDEL=<cid> removes the indicated PDP context and removes all associated data related to the indicated PDP contexts that are not activated. The AT command will not delete or removeinformation for activated PDP contexts. The removed PDP context is listed by the +CGDEL: <cid> intermediate result code.

• If <cid> points to a primary PDP context, the PDP context will be deleted together with all linked secondary PDP

contexts if none of the PDP contexts are activated.

• If <cid> points to a secondary PDP context, the PDP context will be deleted if it is not activated.

A special form of the command can be given as +CGDEL (with the =<cid> omitted). In this form, all primary PDP contexts that are not activated or have any activated secondary PDP contexts will be removed and all secondary PDP contexts that are not activated will be removed. The associated data of all the deleted PDP contexts will be removed, and the removed PDP context are listed by the +CGDEL: <cid>[,<cid>[,...]] intermediate result code. Activated PDP contexts will not cause this form of the command to return ERROR or +CME ERROR.

Note, +CGDEL will remove associated PDP context data that can be set by the AT commands +CGDCONT, +CGDSCONT, +CGTFT, +CGEQREQ, +CGEQMIN and +CGEQOS. For an attempt to delete PDP context(s) which would violate these rules, a +CME ERROR response is returned.

Execution Command AT+CGDEL=<cid>] Response

• +CGDEL: <cid>[,<cid>[,…]]

• OK

• If error is related to wrong AT syntax:

+CME ERROR: <err> Parameters <cid>: a numeric parameter which specifies a particular PDP context Definition.

AT+CGAUTH Define PDP Context Authentication Parameters

Set command allows the user to specify authentication parameters for a PDP context identified by the (local) context identification parameter <cid> used during the PDP context activation and the PDP context modification procedures. Since the <cid> is the same parameter that is used in the +CGDCONT and +CGDSCONT commands, +CGAUTH is effectively as an extension to these commands.

Note, this AT command transfers information in the clear that can be regarded as sensitive in security terms. Care must be exercised in providing this command where the AT commands are used in insecure The read command returns the current settings for each defined context. The test command returns values supported as a compound value.
