PDS6 - Sending PDU using AT+CMGC | Telit Cinterion IoT Developer Community

April 7, 2016 - 2:33pm, 4704 views

Hello

I'm in the process of upgrading from the EGS3 to the PDS6 and I've come across this problem.

I wish to use the AT+CMGC to send PDUs but it fails every time (the SMS doesn't get sent) with CMS ERROR 303 (operation not supported). If I use AT+CMGS it works fine, but I want the functionality that +CMGC provides of advising if the SMS fails to send.

The PDU attempt is as follows (I've edited the phone number for privacy)

AT+CMGC=29

0011000C914412121212120000AD1154747A0E22BFCB73F7890EBABFE56B

+CMS ERROR: 303

If I send this same PDU with AT+CMGS is works fine.

AT+CMGS=29

0011000C914412121212120000AD1154747A0E22BFCB73F7890EBABFE56B

+CMGS: 13

OK

ATI returns:

Cinterion
PDS6
REVISION 03.001
OK

Any advice will be gratefully received.

Regards
Steve
