I am trying to execute some USSD commands with sim800 and store the result.
I need to enable `ring` interupt for USSD commands just like calls and sms.

Here is my Sim800 code for using ussd:

   

AT+CUSD=1,"[some ussd]",15

 Please note that my code works fine without the ring interupt but I need a way to it with interupts.

Thanks

Has this anything to do with AVRs?? Can you divulge more information?

Perhaps this can be enabled with the AT+CFGRI=1 command (untested), since the hardware manual states that certain unsolicited result codes can be signaled via the ring indicator pin. Not sure which URCs will trigger the RI pin...

 

PS: perhaps this belongs to the 'General Electronics" sub forum?

I tried AT+CFGRI=1 as u suggested. It's still not working. I looked into the datasheet for URCs and didn't find anything related to USSD commands.
