I am sorry, I just discovered bug in the application, problem was solved by replacing

err = send(sock, message, sizeof(message) - 1, 0);

with

err = send(sock, message, strlen(message), 0);

Are you certain that the server receives the payload? Do you have any logs or similar from the server side where you can see that the "message" is received?

Can you share the SLM commands that you used, where this worked as expected?

Kind regards,

Håkon

Hi,
yes, this sample does work, however I have a problem with receiving data from server and UDP sample only handles transmits data to server.

Hi,

Does the stock cellular/udp sample work as expected on your end? There's already a kconfig present to change server / payload etc here: https://github.com/nrfconnect/sdk-nrf/blob/v2.6.1/samples/cellular/udp/Kconfig#L25

Kind regards,
