<![CDATA[NB-IoT: How to send data in Non-IP mode]]>I have recently achieved non-IP call with FiPy with the recent Sequans SW 37781 using the below:

send_at_cmd_pretty('AT+CGDCONT=1,"Non-IP","<APN_NAME>"')
lte.attach(band=3)

The session is successful (attached S1-MME interface trace) can be found at the end.
My query is how we can "inject" a non IP data packet using the socket lib and socket objects, as the classic AF_INET family needs a 5-tuple containing IP addresses and port details.
Alternative solution can be a relevant Socket Dial: +SQNSD AT command but with no IP addresses and ports assigned?
Some trials with AF_INET and SOCK_RAW were not successful. Can you help please?

Also, how did you get the packet into wireshark?
