Hi, I’m doing some test with Sierra Wireless modem 1.8 mc8775 with default configuration.
The only thing I changed is AT+CNMI=2,1,0,2,0. When I send an SMS (pdu mode obviously) with SRR enabled (status report) I never see the +CSDI URC coming back!
I did exactly the same test (same PDU, same configuration) with other 2 gsm modems of different manufacturers and I correctly see the +CSDI URC coming back.
Am I missing some proprietary configuration? Is this a bug?
