PDS6 - Sending PDU using AT+CMGC | Thales IoT Developer Community
April 7, 2016 - 2:33pm, 4096 views
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)
+CMS ERROR: 303
If I send this same PDU with AT+CMGS is works fine.
Any advice will be gratefully received.
