I developed a small application in VB6 & also Java for SIM Application Toolkit. I developed & tested the application using 'Q2406H, module. It works great with this module; but when I use ‘Fastrack Supreme 10 (Q2687H)’ the application fails to work.
I have done a 100 trial runs on Hyperterminal with both the modems before concluding that it is definately an issue with the Supreme 10 modem.
I have configured the Supreme 10 modem with AT+STSF=2,“FFFFFFFF7F01005F3E”,6,1 command. Yes, I also activated it by issuing AT+STSF=1 & then rebooting with AT+CFUN=1
Here 's what actually happens when I try to ‘Check Balance’ (Menu item of the SIMs STK);
I start with the STK Main Menu : AT+STGI=0
I keep moving through the menus till I Get the +STGI: 3,5,“Stock Balance”,0 option.
Then I issue: AT+STGR=6,1,3
Modem responds: +STIN: 3
Then the following interaction takes place: AT+STGR=3,1
+STGI: “Sending SMS”
+STGI: 0,“SMS Failed”,0
If I do the same thing with Q2406H, the message is sent successfuly, for which I also get a response.
Please HELP ME OUT!!!
