I'm trying to display a little message to the screen everytime a SMS is received. After looking through the pager code, I took a stab at it. The basic code looks like:


Code:
/* message to display when we receive an SMS message*/
u8 PROGMEM sms_display_msg[] = "SMS message received!";

/* Function used to deal with the SMS action */
void action_sms(File_apdu_data *fd)
{
   dbsp ("Got the SMS\n");
   display_text_raw(sms_display_msg, Q_DISPLAY_TEXT_USER_CLEAR);
}


void turbo_handler (u8 action, void* data)
{
   switch(action)
   {
      case ACTION_INSERT_MENU:
         /* make something appear in the menu*/
         insert_menu ("SMS check");
         break;
         
      case ACTION_SMS:
         /* SMS received, display text*/
         stk_thread (action_sms, data);
         break;
         
      case ACTION_APP_REGISTER:
         reg_action (ACTION_SMS);
      break;
         
      default:
      break;
   }
}


I tried to register the SMS action both using ACTION_APP_INIT and ACTION_APP_REGISTER (commenting out one then the other). Also I tried both dbsp() and display_text_raw() to show the text, commenting out one then the other. In every case, nothing happens on the screen after sending an SMS. Looking at the trace, there is an unknown envelope command that happens after the SMS is received, but I don't know what that is.

Note: I tried helloworld on the phone and the text there displayed fine.

What am I doing wrong?

I should probably mention that I'm doing this using the TurboSIM. I'm programming it with the Programmer. The text inserted into the menu is just a sanity check to make sure that the program was downloaded to the SIM OK.

Your code looks ok, it's possible that SMS is not actually stored on SIM and kept in phone memory. This behaviour is phone dependant. You may try to fill internal phone memory and keep sim free.

I have tried a few more things and have narrowed things down a bit. In sending the SMS from an emulator, if I use a PID of 0x7F (comes to SIM as envelope command), the card seems to crash (card connection error). If instead I use a PID of 0x41 (arrives as an update record), the code works perfectly and the text is displayed fine.

I added registration for all the SMS actions I could find (including Turbo SMS), and have a separate function and text display for each action, but that has not changed anything. Depending on the PID the code works or the card crashes. But I don't want to rely on the PID, I want to be able to cover all cases.

Any ideas?

pz -- I have been doing some more testing as I have time. I now have it so that there is no crashing, but there is still a PID problem. I can use any PID except 0x7F to send an SMS and have the code work. If I use a PID of 0x7F, nothing happens, no crash, no message; although I can see where the SIM gets it and responds with a MO SMS if the OTA setup (in the emulator) requests it.

I know that often the Turbo SMS will pick up on that PID and try to do some filtering on it, but even if I go to the setup and change the PID to use 0x00 for turbo SMS, still no action event happens for incoming SMS's with a PID of 0x7F. Is there anything I can do to make sure the Turbo generates some kind of event for that SMS? Any kind of action would be nice.

Thanks

As for 0x7F/Turbo SMS - have you tried e.g. locate application? Good for testing. Or you can use Setup->Turbo SMS->Test.

Your goal is to have SMS stored on SIM - this is not PID but DCS related - class says how the incoming SMS should be handled. Generic SMS are class 0 meaning it's up to phone where to store it but you can say "store it into SIM".
