List of AT-commands

Commands always start with AT (which means ATtention) and finish with a <CR> character.

Information responses and result codes

Responses normally start and end with <CR><LF>, except when the modem is set to “short result code format” with the command ATV0, or when the ATQ1 (no result codes) command is used.

If command syntax is incorrect, an ERROR string is returned. If extended error result codes are configured (+CMEE) and if command syntax is correct but with some incorrect parameters, the +CME ERROR: <Err> or +CMS ERROR: <SmsErr> strings are returned with different error codes. If the command line has been performed successfully, an OK string is returned. In some cases, such as “AT+CPIN?” or (unsolicited) incoming events, the product does not return the OK string as a response.

In the AT-command list below, <CR> and <CR><LF> are intentionally omitted.

Special AT-commands

In addition to the commands listed below there are two special commands that do not start with AT.The first command is “A/” without any <CR>.This command makes the modem repeat the last entered command.The second special command is the “+++” (also without <CR>).This command is called “escape sequence” and is used when the modem is in dedicated mode (online mode).When entering “+++” in dedicated mode, the modem will switch from “online mode” to “online command mode”.This means that it is possible to send commands to the local modem.The escape sequence is useful when disconnecting the active call.The disconnection is made with the ATH command (see the list of AT-commands below).The ATO command can also be used when in “online command mode”.

12 6196-2220

+WPCS – Phonebook Character Set

Description:

This specific command informs the ME which character set is used by the TE for the phonebooks.The ME can convert each character of entered or displayed strings. This is used to read or write phonebook entries. See also +CSCS for the short messages character sets.

Syntax:

AT+WPCS=<Character Set>

Syntax:

AT+CIMI

Command example Possible responses Note

AT+CIMI 208200120320598 IMSI value (15 digits)

136196-2220

+CCID – Card Identification

Description:

This command orders the product to read the EF-CCID file on the SIM card. If there is no EF-CCID file present on the SIM, the +CCID answer will not be sent, but the OK message will be returned.

Syntax:

AT+CCID

Command example Possible responses Note

OK commands

+CPOF – Power down modem software

Description:

This specific command stops the GSM software stack as well as the hardware layer. The AT+CFUN=0 command is equivalent to +CPOF.

Syntax:

AT+CPOF

Command example Possible responses Note

AT+CPOF OK Command valid

14 6196-2220

+CFUN – Set phone functionality

Description:

This command selects the mobile station’s level of functionality.When the application wants to stop the product with a power off, or if the application wants to force the product to execute an IMSI DETACH procedure, then it must send:

AT+CFUN=0 (equivalent to AT+CPOF)

This command executes an IMSI DETACH and makes a backup copy of some internal parameters in SIM and in EEPROM.The SIM card cannot then be accessed. If the mobile equipment is not powered off by the application after this command has been sent, a re-start command

AT+CFUN=1

...will have to be issued to restart the whole GSM registration process. If the mobile equipment is turned off after this command, then a power on will automatically restart the whole GSM process.The AT+CFUN=1 command restarts the entire GSM stack and GSM functionality: a complete software reset is performed.All parameters are reset to their previous values if AT&W was not used.

If you write entries in the phonebook (+CPBW) and then reset the product directly (AT+CFUN=1, with no previous AT+CFUN=0 command), some entries may not be written (the SIM task does not have enough time to write entries in the SIM card). In addition, the OK response will be sent at the last baud rate defined by the +IPR command.With the autobauding mode the response can be at a different baud rate, it is therefore preferable to save the defined baud rate with AT&W before directly sending the AT+CFUN=1 command.

Syntax:

AT+CFUN=<functionality level> <functionality level> may be one of the following parameters 0 Execute an IMSI detach

1 Restart the whole GSM registration process.

Command example Possible responses Note

AT+CFUN? +CFUN: 1 Full functionality indicated

OK Command valid AT+CFUN=0 OK Detach from network. AT+CFUN=1 OK Set the full functionality

mode with a complete software reset

156196-2220

+CPAS – Phone activity status

Description:

This command returns the activity status of the mobile equipment.

Syntax:

AT+CPAS

Command example Possible responses Note

AT+CPAS +CPAS: <pas> Current activity status OK Defined values:

<pas> may be one of the following parameters 0 ready (allow commands from TA/TE)

1 unavailable (does not allow commands) 2 unknown 3 ringing (ringer is active) 4 call in progress 5 asleep (low functionality)

+CMEE – Report Mobile Equipment Errors

Description:

This command disables or enables the use of the “+CME ERROR: <xxx>” or “+CMS ERROR:<xxx>” result code instead of simply “ERROR”.

See chapter ”error codes” for ”+CME ERROR” result codes description and ”+CMS ERROR” result codes.

Syntax:

AT+CMEE=<error reporting flag> <error reporting flag> may be one of the following parameters 0 Disable ME error reports, use only ”ERROR”

1 Enable long error reports, ”+CME ERROR xxx”

or ”+CMS ERROR xxx”

Command example Possible responses Note

AT+CMEE=0 OK Disable ME error reports,

use only « ERROR »

AT+CMEE=1 OK Enable

”+CME ERROR: <xxx>” or ”+CMS ERROR: <xxx>”

16 6196-2220

+CKPD – Keypad control

Description:

This command emulates the ME keypad by sending each keystroke as a character in a <keys> string.The supported GSM sequences are listed below in this manual. If emulation fails, a +CME ERROR: <err> is returned. If emulation succeeds, the result depends on the GSM sequence activated.

NOTE: In the case where the FDN phonebook is activated, the sequences concerning

“call forwarding” are allowed only if the entire sequence is written in the FDN.

Syntax:

AT+CKPD=<keys> <keys> may be a string of the following characters 0-9,*,# characters allowed in the keypad control string

Command example Possible responses Note

AT+CKPD=”*#21#” +CCFC: 0,7 Check every call

forwarding status

AT+CKPD=”1234” +CME ERROR 3 Sequence not allowed

+CCLK – Clock Management

Description:

This command is used to set or get the current date and time of the ME real-time clock. Default date/time is “98/01/01,00:00:00” (January 1st, 1998 / midnight).

Syntax:

AT+CCLK=<date and time string> <date and time string> is a string with the following format: “yy/MM/dd,hh:mm:ss” Valid years are 98 (for 1998) to 97 (for 2097).

The seconds field is not mandatory.

Call Control commands

D and DL – Dial command

The ATD command is used to data or fax call. As per GSM 02.30, the dial command also controls supplementary services.

For a data or a fax call, the application sends the following ASCII string to the product (the bearer must be previously selected with the +CBST command):

ATD<nb> where <nb> is the destination phone number.

For a voice call, the application sends the following ASCII string to the product: (the bearer may be selected previously, if not a default bearer is used).A voice call must be used when sending DTMF tones.

ATD<nb>; where <nb> is the destination phone number.

Please note that for an international number, the local international prefix does not need to be set (usually 00) but does need to be replaced by the ‘+’ character.

Example: to set up a data call to the Westermo Sweden office from another country, the AT command is:“ATD+4616428000”

Note that some countries may have specific numbering rules for their GSM handset numbering.

The ATDL command dials the last valid dialled number.

The response to the ATD command is one of the following:

Verbose result code Numeric code Description with ATV0 set

OK 0 if the call succeeds, for

voice call only

CONNECT <speed> 10,11,12, 13,14,15 <speed> if the call succeeds, for

data calls only takes the value negotiated by the product.

BUSY 7 If the called party is

already in communication

NO ANSWER 8 If no hang up is detected

after a fixed network time-out

NO CARRIER 3 Call setup failed or

remote user release. Use the AT+CEER command to know the failure cause

196196-2220

Direct dialling from a phonebook (stored in the SIM card) Direct dialling can be performed with the following command: ATD> <index>; to call <index> from the selected phonebook

(by the +CPBS command)

ATD> “BILL”; to call “BILL” from the selected phonebook ATD> mem <index> (mem is “SM”, “LD”,“MC”,“ME”, “RC”,“MT” or “SN”,

see +CPBS command) allows direct dialling from a phonebook number. Does not function with "ON" mem..15

Syntax:

ATD<nb>[<I>][;] ATD>[<mem>]<index>[<I>][;] ATD>[<mem>]<name>[<I>][;]

<nb> is the number to dial.

Command example Possible responses Note

AT+CPBS? +CPBS:”SM”,8,10 ADN phonebook is

selected, 8 locations are used and 10 locations are available

ATD>SM6; OK Call index 6 from

AND phonebook and call succeeds

Command specific information

When the FDN phonebook has been locked, only numbers beginning with the digits of FDN phonebook entries can be called. For example, if “014629” is entered in the FDN phonebook all the phone numbers beginning with these 6 digits can be called.

The CLIR supplementary service subscription can be overridden for this call only. “I” means “invocation” (restrict CLI presentation). “i” means “suppression” (allow CLI presentation).

Control of CUG supplementary service information by “G” or “g” is allowed for this call only.The index and info values set with the +CCUG command are used.

An outgoing call attempt could be refused if the AOC service is active and credit has expired (NO CARRIER).

When trying to set up an outgoing call while there is an active call, the active call is first put on hold, then the call set up is carried out.

As per GSM 02.30, GSM sequences may be controlled using dial commands.These sequences can contain “*”,“#”, but “;” is forbidden. If the sequence is not supported or fails, +CME ERROR: <err> is returned. In the case where the FDN phonebook is activated, the sequences concerning call forwarding are allowed only if there are written in the FDN.

Example of using GSM sequences:

Command example Possible responses Note

done. ATD*2# +CME ERROR 3 Bad sequence See the enf of the manual for the list of supported sequences.

H – Hang-Up command

Description:

The ATH (or ATH0) command is used by the application to disconnect the remote user. In the case of multiple calls, all calls are released (active, on-hold and waiting calls). The ATH1 command disconnects the current outgoing call, only in dialing or alerting state (ie. ATH1 can be used only after the ATD command, and before its terminal response (OK, NO CARRIER, ...). It can be useful in the case of multiple calls.

Syntax:

ATH

Command example Possible responses Note

+COPS – Operator selection

Description:

There are three possible ways of selecting an operator (PLMN):

• The product is in manual mode. It then tries to find the operator specified by the application and if found, tries to register.

• The product is in automatic mode. It then tries to find the home operator and if found, tries to register. If not found, the product automatically searches for another network.

• The product enters into manual/automatic mode, and then tries to find an operator as specified by the application (as in manual mode). If this attempt fails it enters automatic mode. If this is successful, the operator specified by the application is selected. The mobile equipment then enters into automatic mode.

NOTE:The read command returns the current mode and the currently selected operator. In manual mode, this PLMN may not be the one set by the application (as it is in the search phase). These commands are not allowed during one communication.

Syntax:

To force an attempt to select and register on a network, the application must send the following command: Command syntax:AT+COPS=<mode>, [<format> [ , <oper> ] ]

Possible responses: AT+COPS=<mode>:

OK (Network is selected with full service) +CME ERROR: 30 (No network service)

+CME ERROR: 32 (Network not allowed – emergency calls only) +CME ERROR: 3 (Not allowed during one Communication) +CME ERROR: 4 (Incorrect parameters) +CME ERROR: 527 (Please wait, and retry your selection later) +CME ERROR: 528 (Location update failure – emergency calls only) +CME ERROR: 529 (Selection failure – emergency calls only)

Security commands

+CPIN – Enter PIN

Description:

This command is used to enter the ME passwords (CHV1 / CHV2 / PUK1 / PUK2, etc.), that are required before any ME functionality can be used. CHV1/CHV2 is between 4 and 8 digits long, PUK1/PUK2 is only 8 digits long. If the user application tries to make an outgoing call before the SIM PIN code (CHV1) has been confirmed, then the product will refuse the “ATD” command with a “+CME ERROR: 11” (SIM PIN required). The application is responsible for checking the PIN after each reset or power on – if the PIN was enabled.

Syntax:

AT+CPIN=<pin>

Command example Possible responses Note

AT+CPIN=1234 OK Enter PIN, result: PIN

code is correct

AT+CPIN=5678 +CME ERROR: 3 Enter PIN, Operation not

allowed, PIN previously entered

After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the PUK (Personal Unblocking Key) will be required. PUK validation forces the user to enter a new PIN code as a second parameter and this will be the new PIN code if PUK validation succeeds. CHV1 is then enabled if PUK1 is correct.

The application therefore uses this command: AT+CPIN=<Puk>,<NewPin>

Command example Possible responses Note

AT+CPIN=00000000,1234 +CME ERROR: 16 Enter PUK and new PIN,

result: Incorrect PUK

AT+CPIN=12345678,1234 OK Enter PUK and new PIN,

2nd attempt, PUK

correct, new PIN stored To ascertain which code must be entered (or not), the following query command can be used: AT+CPIN?

The possible responses are:

+CPIN: READY ME is not pending for any password +CPIN: SIM PIN CHV1 is required +CPIN: SIM PUK PUK1 is required +CPIN: SIM PIN2 CHV2 is required +CPIN: SIM PUK2 PUK2 is required +CPIN: PH-SIM PIN SIM lock (phone-to-SIM) is required +CPIN: PH-NET PIN Network personnalisation is required +CME ERROR: <err> SIM failure (13) absent (10) etc.

356196-2220

Please note that in this case the mobile equipment does not end its response with the OK string.The response +CME ERROR: 13 (SIM failure) is returned after 10 unsuccessful PUK attempts.The SIM card is then out of order and must be replaced by a new one.

Example:

3 failed PIN validations + 1 successful PUK validation

Command Responses Note

AT+CPIN? +CPIN: SIM PIN Read the PIN status

The product requires SIM PIN

AT+CPIN=1235 +CME ERROR: 16 First attempt to enter a

SIM PIN,Wrong PIN

AT+CPIN=1236 +CME ERROR: 16 Second attempt,

Wrong PIN

AT+CPIN=1237 +CME ERROR: 16 Third attempt,

Wrong PIN

AT+CPIN? +CPIN: SIM PUK Read PIN state,The prod-

uct requires PUK

AT+CPIN=99999999,5678 OK The PUK is entered, the

new PIN shall be 5678 PUK validation is OK. New Pin is 5678

AT+CPIN? +CPIN: READY Read PIN state,

the product is ready

If the user tries to do something which requires PIN2 (CHV2), the product will refuse the action with a “+CME ERROR: 17” (SIM PIN2 required).The product then waits for SIM PIN2 to be given. Of course, if SIM PIN2 is blocked, SIM PUK2 is required instead of SIM PIN2. For example, the product needs PIN2 to write in the fixed dialling phonebook (FDN), so if SIM PIN2 authentication has not been performed during the current session, SIM PIN2 is required.

Command example Possible responses Note

AT+CPBS=”FD” OK Choose FDN AT+CPBW=5,”01290917”, Write in FDN at location

129,”Jacky” +CME ERROR: 17 5, SIM PIN2 is required AT+CPIN? SIM PIN2 SIM PIN2 is required AT+CPIN=5678 OK Enter SIM PIN2 AT+CPBW=2,”01290917”, Write in FDN at location

129,”Jacky” OK 5, now writing in FDN is

allowed

Please note that the product only requests PIN2 or PUK2 once.Therefore, if they are not entered properly, the next +CPIN? command will return “+CPIN: READY”.

36 6196-2220

+CPIN2 – Enter PIN2

Description:

This specific command is used to validate the PIN2 code (CHV2), or to validate the PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code. Of course, the +CPIN command allows PIN2 or PUK2 codes to be validated, but only when the last command executed resulted in PIN2 authentication failure. PIN2 length is between 4 and 8 digits, PUK2 length is 8 digits only.

Syntax:

AT+CPIN2=<pin2>

Command example Possible responses Note

AT+CPIN2=1234 OK Enter PIN2,

code is correct

AT+CPIN2=5678 +CME ERROR: 3 Enter PIN2, operation not

allowed, PIN2 previously entered

After 3 unsuccessful attempts, PUK2 will then be required. PUK2 validation forces the user to enter a new PIN2 code as a second parameter and this will be the new PIN2 code if PUK1 validation succeeds.The application therefore uses this command:

AT+CPIN2=<puk2>,<NewPin2>

Command example Possible responses Note

AT+CPIN2=00000000,1234 +CME ERROR: 16 Enter PUK2 and new

PIN2, Incorrect code (PUK2)

AT+CPIN2=12345678,1234 OK Enter PUK2 and new

PIN2, 2nd attempt PUK2 correct, new PIN2 stored To find out which code must be entered (or not), the following query command can be used:

AT+CPIN2? +CPIN2: READY No PIN2 is needed

+CPIN2: SIM PIN2 PIN2 is required +CPIN2: SIM PUK2 PUK2 is required +CME ERROR: <err> Absent (10) etc...

376196-2220

+CPINC – PIN remaining attempt number

Description:

This specific command is used to get the number of valid attempts for PIN1 (CHV1), PIN2 (CHV2), PUK1 (UNBLOCK CHV1) and PUK2 (UNBLOCK CHV2) identifiers.

Syntax:

AT+CPINC

Response Syntax

+CMGF – Preferred Message Format

Description:

The message formats supported are text mode and PDU mode. In PDU mode, a complete SMS Message including all header information is given as a binary string (in hexadecimal format).Therefore, only the following set of characters is allowed: {‘0’,’1’,’2’,’3’,’4’,’5’,’6’,’7’,’8’,’9’,‘A’, ‘B’,’C’,’D’,’E’,’F’}. Each pair or characters is converted to a byte (e.g.:‘41’ is converted to the ASCII character ‘A’, whose ASCII code is 0x41 or 65). In Text mode, all commands and responses are in ASCII characters. The format selected is stored in EEPROM by the +CSAS command.

Syntax:

AT+CMGF

Command example Possible responses Note

address

Defined values:

The <pdu> message is composed of the SC address (« 00 means no SC address given, use default SC address read with +CSCA command) and the TPDU message. In this example, the length of octets of the TPDU buffer is 14, coded as GSM 03.40. In this case the TPDU is: 0x01 0x03 0x06 0x91 0x21 0x43 0x65 0x00 0x00 0x04 0xC9 0xE9 0x34 0x0B, which means regarding GSM 03.40:

<fo> 0x01 (SMS-SUBMIT, no validity period) <mr> (TP-MR) 0x03 (Message Reference) <da> (TP-DA) 0x06 0x91 0x21 0x43 0x65 (destination address +123456) <pid> (TP-PID) 0x00 (Protocol Identifier) <dcs> (TP-DCS) 0x00 (Data Coding Scheme: 7 bits alphabet) <length> (TP-UDL) 0x04 (User Data Length, 4 characters of text) TP-UD 0xC9 0xE9 0x34 0x0B (User Data: ISSY)

TPDU in hexadecimal format must be converted into two ASCII characters, e.g. octet with hexadecimal value 0x2A is presented to the ME as two characters ‘2’ (ASCII 50) and ‘A’ (ASCII 65).

+WMGO – Message overwriting

Description:

The +CMGW command writes an SMS to the first location available.To write an SMS to a specified location, the +WMGO command forces the product to write an SMS (with the +CMGW command) to the location specified with +WMGO, but for just one +CMGW command.

Syntax:

AT+WMGO= <loc>

Defined values: <loc>

location number of the SIM record to write or overwrite

Possible responses:

OK if <loc> is a valid SMS location, for AT+WMGO=?

and for AT+WMGO? +CMS ERROR: 321 if <loc> is out of the SIM capacity range. +WMGO: <loc> for AT+WMGO?

On the next AT+CMGW command, the record number used will be the one specified by the AT+WMGO command. The location is forgotten and, in order to perform a second overwrite, +WMGO has to be used again. If the external application specifies a free location, and if an incoming message is received before the AT+CMGW command, the product may store the incoming message at a location available.This could be the one specified by +WMGO (the product does not prevent from this). If the user then issues an AT+CMGW command without changing the AT+WMGO location, the new message will be overwritten!

NOTE: that this location number is not kept over a software reset.

+CUSD – Unstructured supplementary service data

Description:

The USSD supplementary service is described in GSM 02.90. It is based on sequences of digits which may be entered by a mobile user with a handset.A sequence entered is sent to the network which replies with an alphanumerical string, for display only, or for display plus request for the next sequence.

This command is used to:

• enable or disable the CUSD indication sent to the application by the product when an incoming USSD is received

• send and receive USSD strings

Syntax:

AT+CUSD = <n> [ ,<str> [ <dcs> ] ]

Defined values: <n>

0: Disable the result code presentation 1: Enable the result code presentation 2: Cancel session (not applicable to read command response) In case of
