Hi!

Of course! To use AT commands for this you will need to be running the Serial LTE Modem application available in NCS, which has support for proprietary AT commands like UDP AT commands.

AT+CFUN=1 //to turn on the modem

AT+CFUN? //to confirm that the modem is turned on

AT+CEREG=5 //to enable unsolicited notfiications

//wait for a connection, +CEREG: 5

AT#XSOCKET=1,2,1 //open a UDP socket with role = server

(or AT#XSOCKET=1,2,0 //open a UDP socket with role = client)

Then you can use AT#XSOCKETOPT to set socket options

AT#XSENDTO=<url>,<port>,<datatype>,<data> //to send data

Let me know if there's anything else you need!

Best regards,

Heidi
