2 AT COMMANDS FEATURES

2.1 Serial Link Settings

The serial link handler has the following factory settings:

115200 bps baud rate(option to configure to other baud-rate upon customer’s request)

8 bits data

1 stop bit

None parity

RTS/CTS flow control

The commands +IPR, +IFC, +ICF can be used to configure the Serial Link.

2.2 AT Commands Syntax

To control the GSM/GPRS module, one can simply send the AT commands via its serial interface.

Commands always start with the prefix “AT” or “at’ and end with the command line <enter> or <CR> character.

Parameters shown in the bracket [] are optional, which means when the command is executed without these

parameters, their default values are used.

Several AT commands may be combined on the same command line. This eliminates the need to type “AT” or

“at” repeatedly for each command and is only needed once at the beginning of the command line. The

semicolon “;” must be used as a command separator.

Note:

Appending AT commands should generally be avoided, as the expected response might not be received.

For most command syntaxes except for ATV0 and ATQ1, responses start and end with <CR><LF>

If command line has been executed successfully, an “OK” is returned

If command syntax is incorrect, the “ERROR” string is returned.

If command syntax is correct but transmitted with wrong parameters, the “+CME ERROR:

Confidential





7

<err>” or “+CMS ERROR” <SmsErr>” string is returned in case CMEE was previously set to 1 and only

“ERROR” in case CMEE is set to 0 (default value)

2.3 AT Commands Presentation

The AT commands are presented in this document as follow:

Description section provides general information on the AT command objective and behavior

Notes section, if any, provides remarks on how to use command

Getting/Setting section provides general syntax for setting and getting the values

Command Syntax section describes command and response syntaxes and examples presenting the real use

of that command

Defined Values section describes all parameters and values supported including default values, if available

2.4 SIM Insertion and Removal

SIM Card insertion and removal are supported and detected by a SIM Detect pin. This pin is constantly

monitored for changes in state.

When the SIM detect pin indicates that a card is present, a SIM card initialization session will be triggered. If a

valid SIM card is detected, the SIM card initialization session will be executed. The AT+CPIN? Command will

return various responses for the following:

If card inserted is a SIM Card, the response displayed +CPIN: XXXX will indicate the current SIM status.

If card inserted is not SIM card, the response displayed will be +CME ERROR: 10 (SIM not inserted)

During the SIM initialization, the response +CME ERROR: 515 (Initialization of SIM in progress) will be

displayed. (Note: Timing for initialization of SIM varies if SIM user data files are very large)

When the SIM Detect pin detects card absence due to SIM card removal, an IMSI detach procedure will be

performed. This will bring the module into emergency mode state where all user data relating to the SIM will

be made unavailable.

For unsolicited responses of SIM removal, the AT-Command $CTRACE can be enabled.

Confidential

2.5 Wrong Firmware Message

When a firmware is downloaded into a module with unmatched configuration, “IMEI ERROR” or “SEC ERROR”

message will appear. To avoid this scenario, always ensure firmware with the correct configuration is

downloaded into your module.

Set command selects the procedure, how receiving of new messages from the network is indicated to the TE

when TE is active, e.g. DTR signal is ON. If TE is inactive (e.g. DTR signal is OFF), message receiving should be

done as specified in 3GPP TS 23.038 [2].

Note: When DTR signal is not available or the state of the signal is ignored (V.25ter command &D0), reliable

message transfer can be assured by using +CNMA acknowledgement procedure.

<mode> controls the processing of unsolicited result codes specified within this command, <mt> sets

the result code indication routing for SMS-DELIVERs, <bm> for CBMs and <ds> for SMS-

STATUS-REPORTs. <bfr> defines the handling method for buffered result codes when

<mode> 1, 2 or 3 is enabled. If ME does not support requested item (although TA does), final

result code +CMS ERROR: <err> is returned. See chapter Message Service Failure Result Code

for a list of <err> values.

Test command gives the settings supported by the TA as compound values.

Note: Command Select Message Service +CSMS should be used to detect ME support of

mobile terminated SMs and CBMs, and to define whether a message routed directly to TE

should be acknowledged or not (refer command +CNMA).

<mode> (refer figure 2; Note: The buffering mechanism may as well be located in the ME; the setting

affects only to unsolicited result codes specified within this command):

0 Buffer unsolicited result codes in the TA. If TA result code buffer is full, indications can be

buffered in some other place or the oldest indications may be discarded and replaced with

the new received indications.

1 Discard indication and reject new received message unsolicited result codes when TA-TE link

is reserved (e.g. in on-line data mode). Otherwise forward them directly to the TE.

2 Buffer unsolicited result codes in the TA when TA-TE link is reserved (e.g. in on-line data

mode) and flush them to the TE after reservation. Otherwise forward them directly to the TE.

3 Forward unsolicited result codes directly to the TE. TA-TE link specific inband technique used

to embed result codes and data when TA is in on-line data mode.

Note: <mode> Value 3 is not supported as platform does not support the same.

Note: It is possible that ME/TA result code buffer is in volatile memory. In this case messages

may get lost if the power of ME/TA is switched off before codes are sent to TE. Thus, it is not

recommended to use direct message routing (<mt>=2 or 3, <bm>=2 or 3, or <ds>=1) with

<mode> value 0 or 2.

6.16 Send Message +CMGS

Description:

This command sends a SMS.

• Set command lets user send SMS in text mode or PDU mode based on the message format +CMGF.

• Test command will result in “Ok” response.

Execution command sends message from a TE to the network (SMS-SUBMIT). Message reference value <mr> is

returned to the TE on successful message delivery. Optionally (when +CSMS <service> value is 1 and network

supports) <scts> is returned for text mode and <ackpdu> is returned. For PDU mode. Values can be used to

identify message upon unsolicited delivery status report result code. If sending fails in a network or an ME

error, final result code +CMS ERROR: <err> is returned. See chapter Message Service Failure Result Code for a

list of <err> values. This command should be abortable.

entered text (3GPP TS 23.040 [3] TP-Data-Unit) is sent to address <da> and all current settings (refer Set Text

Mode Parameters +CSMP and Service Centre Address +CSCA) are used to construct the actual PDU in ME/TA.

<length> must indicate the number of octets coded in the TP layer data unit to be given (i.e. SMSC address

octets are excluded).

the entered text should be formatted as follows if <dcs> (set with +CSMP) indicates that 3GPP TS 23.038 [2] GSM 7 bit default alphabet is used and

<fo> indicates that 3GPP TS 23.040 [3] TP-User-Data-Header-Indication is not set:

if TE character set other than “HEX” (refer command Select TE Character Set +CSCS in 3GPP TS 27.007

[9]): ME/TA converts the entered text into the GSM 7 bit default alphabet according to rules of Annex

A; backspace can be used to delete last character and carriage returns can be used (previously

mentioned four character sequence shall be sent to the TE after every carriage return entered by the

user);

if TE character set is “HEX”: the entered text should consist of two IRA character long hexadecimal

numbers which ME/TA converts into the GSM 7 bit default alphabet characters. (e.g. 17 (IRA 49 and

55) will be converted to character Π (GSM 7 bit default alphabet 23)).

if <dcs> indicates that 8-bit or UCS2 data coding scheme is used or <fo> indicates that 3GPP TS 23.040

[3] TP-User-Data-Header-Indication is set: the entered text should consist of two IRA character long

hexadecimal numbers which ME/TA converts into 8-bit octet (e.g. two characters 2A (IRA 50 and 65)

will be converted to an octet with integer value 42).

Confidential





81

the PDU shall be hexadecimal format (similarly as specified for <pdu>) and given in one line; ME/TA

converts this coding into the actual octets of PDU.

when the length octet of the SMSC address (given in the PDU) equals zero, the SMSC address set with

command Service Centre Address +CSCA is used; in this case the SMSC Type-of-Address octet shall not

be present in the PDU, i.e. TPDU starts right after SMSC length octet.

sending can be cancelled by giving <ESC> character (IRA 27).

<ctrl-Z> (IRA 26) must be used to indicate the ending of PDU.

Note: concatenated SMS is not supported in C-AT

160 characters if the 7 bit

GSM coding scheme is used, and 140 characters according to the 8 bit GSM coding scheme.

<pdu> For SMS: GSM 04.11 SC address followed by GSM 03.40 TPDU in hexadecimal format: ME/TA

converts each octet of TP data unit into hexadecimal numbers containing two IRA characters

(e.g. octet with integer value 42 is presented to TE as two characters 2A (IRA 50 and 65)). In

the case of CBS: GSM 03.41 TPDU in hexadecimal format.

Note: SIO consumes all SMS commands and also the text entered by user. So C-AT doesnot receive any SMS commands until SIO is fixed!

values) is used to disable/enable the presentation of an unsolicited result +CUSD: <m> [, <str>, <dcs>] to the

TE. In addition, value <n>=2 is used to cancel an ongoing USSD session

When <str> is given, a mobile initiated USSD-string or a response USSD-string to a network initiated operation

is sent to the network. The response USSD-string from the network is returned in a subsequent unsolicited

+CUSD result code.

Note: In case of successful mobile initiated operation, TA implemented according to a version prior to 6 of this standard, waits the USSD response from the network and sends it to the TE before the final result code .This will block the AT command interface for the period of the operation. Such TA does not support <n> value 2. • Read command gives the current status of the result code presentation to the TE (disable/enable).

8.13 Automatic Redialing +XREDIAL

The command allows enabling of automatic redialing if the called party was busy. For this purpose the

command uses the <mode> parameter in order to enable or disable this function. If the function is enabled,

the MS executes after the first unsuccessful attempt to establish a voice call link a lot of further attempts; the

amount of failed repeat attempts is limited by the reason of failure. If the user is busy or the destination is

temporary not obtainable, 10 repeat attempts are allowed; but there are also serious circumstances which

make destination permanent unreachable as unknown or changed numbers – in this case only one repeat

attempt is allowed (s. GSM02.07 annex A). If more then 8 failed call attempts exist, the corresponding phone

number is stored in the blacklist.

This command allows the following handling

10.32 Rx Diversity +XRXDIV

This command is used to allow external control of the Rx Diversity feature during runtime. A supporting

parameter can also be changed. The feature can be enabled or disabled during operation, and one classmark

field may be changed. Readback of the feature enable and the classmark field is also provided.

This command will allow the AP to enable or disable the feature:

<RxDivEnbl> = enabled or disabled

This enable is used primarily by Layer 1 (L1U/3G, L1G/2G), and is applied under different circumstances when

changed. For 3G, the enable setting is changes at the next DCH setup.

For 2G, the enables setting is changes when the UE registers with the network (LocUp/Attach).

There is a default copy of the enable stored in non-volatile memory. This enable may only be changed via

Phonetool. It is intended that this default feature enable will be setup once, during production. The default

setting will be selectable by the customer.

At powerup, the non-volatile copy is read and used to control the feature by L1U and L1G.

When the enable setting is changed using the XRXDIV command, the new setting will override the initial

version, until the next power cycle. The non-volatile copy will not be changed.

The command will also allow the <DARP> field (darp_caps field in the T_CLASSMARK_3 structure) to be set to

one of these values:

Confidential





167

• DARP_NOT_SUPPORTED

• DARP_PHASE_1

• DARP_PHASE_2_TRAFFIC_ONLY

• DARP_PHASE_2_ALWAYS_ON

There is a non-volatile version of the <DARP> setting. This value is preset at production, and can only be

changed via Phonetool.

The default non-volatile DARP setting at production will be DARP_PHASE_2_ALWAYS_ON.

At powerup, the non-volatile <DARP> setting is used. When the field is changed using the XRXDIV command,

the new <DARP> value will be override the powerup version, until the next power cycle. The new selection for

<DARP> will not change the non-volatile default.

Baseband notes

The command in this section is available only if FEAT_STATIC_RXDIV is defined (build).

• Set Command is used to allow external control of the Rx Diversity feature during runtime.

<field>

For <mode>=1 This is the port to be assigned. (1~17) Currently, only 2 has been implemented.

For <mode>=2 NA

For <mode>=3 This parameter sets the time duration (in unit of 1s) from the time the

corresponding event is first observed till this time duration has expired. After this

time has expired, the firmware will again check for this event. If the event is still

present, the hardware indication will be presented and the event will be logged. If

not, nothing will happen. In the event that the timer has not expired and the

module has regained GSM registration, the timer stops counting.

15.7 Enter Data State +CGDATA

Description:

This execution command causes the MT to perform whatever actions are necessary to establish

communication between the TE and the network using one or more GPRS PDP types. This may include

performing a GPRS attach and one or more PDP context activations. If the parameters are accepted, MT

displays the intermediate result code CONNECT on TE and enters the online data state; thereafter data

transfer may proceed. No other commands following +CGDATA in the command line will be processed.

After data transfer is complete, the MT re-enters the command state and the final result code is displayed on

TE. In error case the final result code NO CARRIER or CME ERROR :<error> is displayed.

PS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they

have not already been performed using the +CGATT and +CGACT commands.

If no <cid> is given or if there is no matching context definition, the MT shall attempt to activate the context

with whatever information is available to the MT. The other context parameters shall be set to their default

values.

If the activation is successful, data transfer may proceed.

After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully,

the V.250 command state is re-entered and the MT returns the final result code OK.

• Set command specifies the <L2P> and <cid> to establish data call (csd connection state)

15.22 Automatic Response to a Network Request for PDP Context Activation 'S0'

Description:

The V.250 'S0=n' (Automatic answer) command may be used to turn off (n=0) and on (n>0) the automatic

response to a network request for a PDP context activation.

When the 'S0=n' (n>0) command is received, the MT shall attempt to perform a GPRS attach if it is not already

attached. Failure will result in ERROR being returned to the TE. Subsequently, the MT will announce a network

request for PDP context activation by issuing the unsolicited result code RING to the TE, followed by the

intermediate result code CONNECT. The MT then enters V.250 online data state and follows the same

procedure as it would after having received a +CGANS=1 with no <L2P> or <cid> values specified.

Note:

The 'S0=n' (n=0) command does not perform an automatic GPRS detach.

1 1 Assigns bits 0-5 for SC specific use

In the case where bit 7 = 0 and bit 6 = 0, bit 5 indicates telemetric interworking:

value = 0 : no interworking, but SME-to-SME protocol

value = 1 : telematic interworking

Confidential





249

In the case of telemetric interworking, the following five bit patterns in bits 4..0 are used to indicate different

types of telemetric devices:

4…0

00000 implicit - device type is specific to this SC, or can be concluded on the basis of the address

00001 telex (or teletex reduced to telex format)

00010 group 3 telefax

00011 group 4 telefax

00100 voice telephone (i.e. conversion to speech)

00101 ERMES (European Radio Messaging System)

00110 National Paging system (known to the SC)

values specific to each SC, usage based on mutual agreement between the SME and the SC

(7 combinations available for each SC)

11111 A GSM mobile station. The SC converts the SM from the received TP-Data-Coding-Scheme to

any data coding scheme supported by that MS (e.g. the default).

If bit 5 has value 1 in an SMS-SUBMIT PDU, it indicates that the SME is a telemetric device of a type which is

indicated in bits 4..0, and requests the SC to convert the SM into a form suited for that device type. If the

destination network is ISDN, the SC must also select the proper service indicators for connecting to a device of

that type.

Confidential





250

If bit 5 has value 1 in an SMS-DELIVER PDU, it indicates that the SME is a telemetric device of a type which is

indicated in bits 4..0.

If bit 5 has value 0 in an SMS-DELIVER PDU, the value in bits 4..0 identifies the SM-AL protocol being used

between the SME and the MS.

Note that for the straightforward case of simple MS-to-SC short message transfer the Protocol Identifier is set

to the value 0.

In the case where bit 7 = 0, bit 6 = 1, bits 5..0 are used as defined below:

5…0
