1.3 Conventions and abbreviations

In this document, the GSM engines are referred to as following term:

1) ME (Mobile Equipment);

2) MS (Mobile Station);

3) TA (Terminal Adapter);

4) DCE (Data Communication Equipment) or facsimile DCE(FAX modem, FAX board);

In application, controlling device controls the GSM engine by sending AT Command via its serial interface. The controlling device at the other end of the serial line is referred to as following term:

1) TE (Terminal Equipment);

2) DTE (Data Terminal Equipment) or plainly “the application” which is running on an embedded system;

1.4 AT Command syntax

The "AT" or "at" prefix must be set at the beginning of each command line. To terminate a command line enter <CR>.

Commands are usually followed by a response that includes.”<CR><LF><response><CR><LF>”

Throughout this document, only the responses are presented, <CR><LF> are omitted intentionally.

The AT command set implemented by SIM300D is a combination of GSM07.05, GSM07.07 and

ITU-T recommendation V.25ter and the AT commands developed by SIMCOM.

Note: Only enter AT command through serial port after SIM300D is power on and

Unsolicited Result Code “RDY” is received from serial port. And if unsolicited result code”SCKS: 0” returned it indicates SIM card isn’t present.

All these AT commands can be split into three categories syntactically: “basic”, “S parameter”, and “extended”. These are as follows:

1.4.1 Basic syntax

These AT commands have the format of “AT<x><n>”, or “AT&<x><n>”, where “<x>”is the command, and “<n>”is/are the argument(s) for that command. An example of this is “ATE<n>”, which tells the DCE whether received characters should be echoed back to the DTE according to the value of “<n>”. “<n>” is optional and a default will be used if missing.

1.4.2 S parameter syntax

These AT commands have the format of “ATS<n>=<m>”, where “<n>” is the index of the S



Confidential

SIMCOM

register to set, and “<m>”is the value to assign to it. “<m>” is optional; if it is missing, then a default value is assigned.

1.4.3 Extended Syntax

These commands can operate in several modes, as following table:

Table 1: Types of AT commands and responses

Test command

Read command

Write command

AT+<x>=?

AT+<x>?

The mobile equipment returns the list of parameters and value ranges set with the corresponding Write command or by internal processes.

This command returns the currently set value of the parameter or parameters.

AT+<x>=<…> This command sets the user-definable parameter values.

Execution command AT+<x> The execution command reads non-variable parameters affected by internal processes in the GSM engine

1.4.4 Combining AT commands on the same command line

You can enter several AT commands on the same line. In this case, you do not need to type the

“AT” or “at” prefix before every command. Instead, you only need type “AT” or “or” at the beginning of the command line. Please note to use a semicolon as command delimiter.

The command line buffer can accept a maximum of 256 characters. If the characters entered exceeded this number then none of the command will executed and TA will returns “ERROR”.

1.4.5 Entering successive AT commands on separate lines

When you need to enter a series of AT commands on separate lines, please note that you need to wait the final response (for example OK, CME error, CMS error) of last AT command you entered before you enter the next AT command.

1.5 Supported character sets

The SIM300D AT command interface defaults to the GSM character set. The SIM300D supports the following character sets:

• GSM format

• UCS2

• HEX

• IRA

• PCCP437

• PCDN

• 8859_1

The character set can be set and interrogated using the “AT+CSCS” command (GSM 07.07).



Confidential

SIMCOM

The character set is defined in GSM specification 07.05.

The character set affects transmission and reception of SMS and SMS Cell Broadcast messages, the entry and display of phone book entries text field and SIM Application Toolkit alpha strings.

1.6 Flow control

Flow control is very important for correct communication between the GSM engine and DTE. For in the case such as a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up.

There are basically two approaches to achieve data flow control: software flow control and hardware flow control. SIM300D support both two kinds of flow control.

In Multiplex mode, it is recommended to use the hardware flow control.

1.6.1 Software flow control (XON/XOFF flow control)

Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data flow. It is quite useful in some applications that only use three wires on the serial interface.

The default flow control approach of SIM300D is hardware flow control (RTS/CTS flow control), to enable software flow control in the DTE interface and within GSM engine, type the following

AT command:

AT+IFC=1, 1

This setting is stored volatile, for use after restart, AT+IFC=1, 1 should be stored to the user profile with AT&W.

Ensure that any communications software package (e.g. ProComm Plus, Hyper terminal or

WinFax Pro) uses software flow control.

NOTE:

Software Flow control should not be used for data calls where binary data will be transmitted or received (e.g. TCP/IP) as the DTE interface may interpret binary data as flow control characters.

1.6.2 Hardware flow control (RTS/CTS flow control)

Hardware flow control achieves the data flow control by controlling the RTS/CTS line. When the data transfer should be suspended, the CTS line is set inactive until the transfer from the receiving buffer has completed. When the receiving buffer is ok to receive more data, CTS goes active once again.

To achieve hardware flow control, ensure that the RTS/CTS lines are present on your application platform.

Note

Factory setting is AT+IPR=0（autobauding）.It can be restored with AT&F and AT&Z when you modified the bit rate’s value..

2.2.45.1 AutoBauding

Synchronization between DTE and DCE ensure that DTE and DCE are correctly synchronized and the bit rate used by the DTE is detected by the DCE (= ME). To allow the bit rate to be synchronized simply issue an "AT" or "at" string. This is necessary when you start up the module while autobauding is enabled. It is recommended to wait 3 to 5 seconds before sending the first

AT character. Otherwise undefined characters might be returned.

If you want to use autobauding and autoanswer at the same time, you can easily enable the

DTE-DCE synchronization, when you activate autobauding first and then configure the autoanswer mode.

Restrictions on autobauding operation

z The serial interface has to be operated at 8 data bits, no parity and 1 stop bit (factory setting). z Only the strings .AT. or .at. can be detected (neither .aT. nor .At.). z Unsolicited Result Codes that may be issued before the ME detects the new bit rate (by receiving the first AT command string) will be sent at the previously detected bit rate. z The Unsolicited Result Codes “RDY” and so on are not indicated when you start up the

ME while autobauding is enabled. z It is not recommended to switch to autobauding from a bit rate that cannot be detected by the autobaud mechnism (e.g. 300 baud). Responses to +IPR=0 and any commands on the same line might be corrupted. z See also Chapter 2.2.44.

Autobauding and bit rate after restart

The most recently detected bit rate cannot be stored when module is powered down (Store bit rate determined with AT&W). Therefore, module will detect bit rate again after restart.

6 AT Commands for SIM Application Toolkit

This section defines the AT Commands implemented in SIM300D for the control of the SIM

Application Toolkit protocol, as per specification GSM 11.14. The table in section 6.1 lists the

AT commands supported – these are SIMCOM proprietary commands as no formal specification currently exist defining STK functionality via an AT interface. The parameters supported by each

AT command for the different proactive commands are given in the subsections which follow the main table.

The protocol defined below provides a generic mechanism for the exchange of information between the ME and the application for a typical proactive SIM command.

How to use SIM300D STK AT interface please see document

SIM300D_STK_USER_GUIDE.DOC

SIMCOM

6.1 Overview of Commands, Responses and Result codes

The following tables outline the AT commands, responses and unsolicited result codes applicable for control of the SIM Application Toolkit protocol via the AT command interface.

Notation

+STC:

Description

Unsolicited result code issued by the CI Task to the application to indicate either:

• there is no STK application available on the SIM

• there is a proactive SIM command to retrieve and action end of the current proactive command session – used if the user wishes to terminate the current proactive SIM session.

+STGC=…

+STCR=…

AT command to Get Command parameters for a proactive SIM command from the CI Task. This will be sent from the application after unsolicited result code

+STC: <cmdId> informs it the SIM has issued a proactive SIM command to be performed.

AT command to provide Command Response parameters for a previously executed proactive SIM command. Its purpose is to relay response data to the lower layers of the SIMCOM protocol stack to allow the Terminal Response

SIM command (see [10]) to be returned to the SIM for the current proactive command.

+STPD=…

+STMS=…

AT command to provide Profile Download parameters to the CI Task. This contains information relating to the SIM Application Toolkit capabilities of the application, and is used by the SIMAT task to limit its SAT instruction set accordingly.

Any application plugging into the serial port should send this command or it will be assumed that the application has no SAT support and will therefore never receive any SAT related information.

AT Command for selecting a menu option. On power-up the SIM will send the

Set-Up-Menu proactive indication. The accessory should load and display the menu structure. This AT command should be used to inform SIM300D of the item selected from the list.

+STEV=…

+STRT=…

This command is used to inform the MS that an MMI specific event has occurred.

AT command for setting the automatic response timer used by the CI Task to issue the Terminal Response (no user response) to a proactive command which has not been processed. The default response time is ten seconds, but it is recommended this is increased when performing SIM Toolkit FTA.

+STTONE=… AT command for playing SIM Toolkit Tones in both idle and dedicated mode.

This command should be used in conjunction with the Play Tone proactive command.



Confidential

SIMCOM

6.2 Definition of Unsolicited Result Codes

Not all proactive commands are required to be visible to the application. For example, the proactive commands More Time and Provide Local Information are transparent and therefore do not require an unsolicited result code to be sent to the user. The commands, which are relevant for user interaction in one form or another, are listed in the following tables.

The output generated for strings is controlled by the +CMGF AT command. The factory default for string output is PDU mode where strings are output in HEX. The tables below illustrate the alternative mechanism of TEXT output; this is obtained by using the +CMGF AT command with a parameter of one.

6.2.1 +STC Command

+STC Informs the application of the type of proactive SIM command data awaiting retrieval.

Result Code:

+STC: <cmdId>

Parameters

<cmdId> Hexadecimal format of Type of Command . Unique identifier for the current SIM Toolkit proactive command issued by the SIM -

The following values are supported:

‘10’ Get Acknowledgement For Set Up Call command

‘22’ command

‘23’ command

‘25’ Up

‘28’ Set Up Idle Mode Text command

‘05’ Set Up Event List command

The special case is +STC: 0 that is issued when there is no STK application accessible on the SIM.

The following tables in this section detail the information that is distributed to the application for proactive indications using unsolicited result codes. The information applicable to the proactive command is sent to the application using the +STUD (SIM Toolkit Unsolicited Data) results code.

6.3 ME Initialisation Procedure

On powering up the ME the SIM’s Phase file (EF 0x6FAE) is read. If this indicates the SIM is of

Phase 2+ or greater the ME sends a Terminal Profile command (see [3]) to the SIM to inform it of the SIM Application Toolkit capabilities of the ME. The SIM then limits its instruction set based on this profile. This terminal profile data is configurable and resides in an application layer configuration file for ease of customisation. On sending the Profile Download command The SIM will respond with signals that will provide the ME with information on whether the SIM has a

SIM Toolkit application present.

If on completing ME initialisation the stack determines that the SIM has no STK capability an unsolicited result code +STC: 0 will be issued to indicate to the user that there is no SIM toolkit availability during the current session.

However, if STK information is available for use by the ME/application then the lower layers of the SIMCom Protocol Stack are informed and the first proactive command to be sent from the

SIM to the user will be the Set Up Menu command to allow the available STK menu to be added to the ME’s own menu structure (i.e. unsolicited result code +STC: 25 will be issued by the CI

Task after it has received this proactive command from the SIMAT task.

6.4.3 AT+STPD SIM Toolkit Profile Download

When an application is plugged into the serial port the command interpreter needs to have knowledge of its SAT capabilities to enable it to route all SAT related signaling to that application if required. If this command is not received it will be assumed that any attached application has no

SAT capability and will therefore not send any related signals to it. If the SIM has reported that it does not have any proactive capability then an STC: 0 unsolicited response will be sent to the application.

6.4.6 AT+STRT SIM Toolkit Response Timer Command

When a proactive command is received from the SIM an automatic response timer is started. If this timer expires before the application has provided a suitable response via the +STCR command,



Confidential

SIMCOM

a Terminal Response is sent to the SIM containing a result of No User Response. This AT command allows the automatic response timeout period to be configured by the application at run-time, thus giving it extended time to respond to certain proactive commands (e.g. the Get

Input command may request a long input string to be entered as part of the associated test case).

The default setting for the response timer is ten seconds, and the maximum duration available is one hour.

6.4.7 AT+STTONE SIM Toolkit Tone Command

The application may request a tone to played after receiving the Play Tone proactive command.

The application either starts playing the tone with the requested tone Id, or stops playing the current tone depending on the <mode> parameter. Tones may be played in either idle or dedicated mode.

On completion of the current tone, unsolicited result code +STTONE: 0 will be issued by the CI

Task. However, if <mode>=0 is used to terminate the tone before it has completed playing there will be no unsolicited result code but only a result code of OK generated by the CI Task.

Quality of Service (QOS) is a special parameter of a CID which consists of several parameters itself.

The QOS consists of

The precedence class

The delay class

The reliability class

The peak throughput class

The mean throughput class

And is decided in “requested QOS” and “minimum acceptable QOS”.

All parameters of the QOS are initiated by default to the “network subscribed value (=0)” but the

QOS itself is set to be undefined. To define a QOS use the AT+CGQREQ or AT+CGQMIN command.

Overwrites the precedence class of

QOS of CID 1 and sets the QOS of

CID 1 to be present

Response: all QOS values of CID 1

AT+CGQREQ=1,2

Note: If the mobile is NOT attached by AT+CGATT=1 and the CID is NOT activated before connecting, attaching and activating is automatically done by the AT+CGDATA command.

Some providers require to use an APN to establish a GPRS connection. So if you use the

Microsoft Windows Dial-Up Network and ATD*9… to connect to GPRS you must provide the context definition as part of the modem definition (Modem properties/Connection/Advanced…/Extra settings.) As an alternative, you can define and activate the context in a terminal program (e.g. Microsoft HyperTerminal) and then use the Dial-Up

Network to send only the ATD command.
