I’m using a Q26 Extreme and setting it up using the following AT commands:
AT+CSMS=1 AT+CMGF=0 AT+CNMI=3,2,0,0,1
When i send the module a multi-part SMS (the sms is a few bytes over 1 sms), i get the first PDU with the UDH confirming its multi-part, then respond with the sms ack
but then never get the second part of the sms come through.
Can anyone spot my error or shed any light on the issue?
