SARA N2 UDP receiving problem

0 votes

Using EVK-N2 with SARA-N211 NB-IoT module.

I'm able to send UDP packets with AT + NSOST command. I have UDP echo server which receives UDP from modem with success, and sends answer. But I don't receive +NSONMI URC notification on modem and AT + NSORF don't returns any data

Do I have to globaly enable some notification, or could this be some power saving problem?

Thank you in advance

You would not get URC until modem actually receives data from the server.

The issue could be that the network blocks server >>modem data.

Power save could come into play but modem should still send out URC once data actually arrives.

I would suggest checking with the carrier first.
