<strong>SIM300D</strong> <strong>AT</strong> <strong>Comm<strong>and</strong></strong> <strong>Set</strong><br />
Confidential SIMCOM<br />
6.1 Overview of <strong>Comm<strong>and</strong></strong>s, Responses <strong>and</strong> Result codes<br />
The following tables outline the <strong>AT</strong> comm<strong>and</strong>s, responses <strong>and</strong> unsolicited result codes applicable<br />
for control of the SIM Application Toolkit protocol via the <strong>AT</strong> comm<strong>and</strong> interface.<br />
Notation Description<br />
+STC: Unsolicited result code issued by the CI Task to the application to indicate<br />
either:<br />
• there is no STK application available on the SIM<br />
• there is a proactive SIM comm<strong>and</strong> to retrieve <strong>and</strong> action<br />
end of the current proactive comm<strong>and</strong> session – used if the user wishes to<br />
terminate the current proactive SIM session.<br />
+STGC=… <strong>AT</strong> comm<strong>and</strong> to Get <strong>Comm<strong>and</strong></strong> parameters for a proactive SIM comm<strong>and</strong> from<br />
the CI Task. This will be sent from the application after unsolicited result code<br />
+STC: informs it the SIM has issued a proactive SIM comm<strong>and</strong> to be<br />
performed.<br />
+STCR=… <strong>AT</strong> comm<strong>and</strong> to provide <strong>Comm<strong>and</strong></strong> Response parameters for a previously<br />
executed proactive SIM comm<strong>and</strong>. Its purpose is to relay response data to the<br />
lower layers of the SIMCOM protocol stack to allow the Terminal Response<br />
SIM comm<strong>and</strong> (see [10]) to be returned to the SIM for the current proactive<br />
comm<strong>and</strong>.<br />
+STPD=… <strong>AT</strong> comm<strong>and</strong> to provide Profile Download parameters to the CI Task. This<br />
contains information relating to the SIM Application Toolkit capabilities of the<br />
application, <strong>and</strong> is used by the SIM<strong>AT</strong> task to limit its S<strong>AT</strong> instruction set<br />
accordingly.<br />
Any application plugging into the serial port should send this comm<strong>and</strong> or it<br />
will be assumed that the application has no S<strong>AT</strong> support <strong>and</strong> will therefore<br />
never receive any S<strong>AT</strong> related information.<br />
+STMS=… <strong>AT</strong> <strong>Comm<strong>and</strong></strong> for selecting a menu option. On power-up the SIM will send the<br />
<strong>Set</strong>-Up-Menu proactive indication. The accessory should load <strong>and</strong> display the<br />
menu structure. This <strong>AT</strong> comm<strong>and</strong> should be used to inform <strong>SIM300D</strong> of the<br />
item selected from the list.<br />
+STEV=… This comm<strong>and</strong> is used to inform the MS that an MMI specific event has<br />
occurred.<br />
+STRT=… <strong>AT</strong> comm<strong>and</strong> for setting the automatic response timer used by the CI Task to<br />
issue the Terminal Response (no user response) to a proactive comm<strong>and</strong> which<br />
has not been processed. The default response time is ten seconds, but it is<br />
recommended this is increased when performing SIM Toolkit FTA.<br />
+STTONE=… <strong>AT</strong> comm<strong>and</strong> for playing SIM Toolkit Tones in both idle <strong>and</strong> dedicated mode.<br />
This comm<strong>and</strong> should be used in conjunction with the Play Tone proactive<br />
comm<strong>and</strong>.<br />
