https://devzone.nordicsemi.com/f/nordic-q-a/51974/nb-iot-simple-udp-exampleHello, is there any kind of good practice available about how to generate UDP traffic with the nRF9160DK via NB-IoT for a simple test? As far as I know the AT client example does not support IPv4/v6 commands but https://github.com/Rallare/fw-nrfconnecten-USTelligent Community 13Tue, 10 Sep 2019 10:20:35 GMThttps://devzone.nordicsemi.com/thread/208860?ContentTypeID=1Tue, 10 Sep 2019 10:20:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:382bffed-046d-4eb6-a52e-4899b76ebfbdMJD093<p>There are examples for UDP in that repo you posted.</p> <p>See <a href="https://github.com/Rallare/fw-nrfconnect-nrf/blob/nrf9160_samples/samples/nrf9160/udp_with_psm/src/main.c">https://github.com/Rallare/fw-nrfconnect-nrf/blob/nrf9160_samples/samples/nrf9160/udp_with_psm/src/main.c</a></p> <p>AT Commands are how we interface with and configure the modem but under most applications, the use of sockets will handle data transport.</p> <p>See <a href="https://github.com/Rallare/fw-nrfconnect-nrf/blob/dea99f9afc37c9a69d66d7136d89d38c050a2fde/samples/nrf9160/udp_with_psm/src/main.c#L135">https://github.com/Rallare/fw-nrfconnect-nrf/blob/dea99f9afc37c9a69d66d7136d89d38c050a2fde/samples/nrf9160/udp_with_psm/src/main.c#L135</a> for how a socket is setup in code for UDP transport.</p> <p>Refer to <a href="https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/include/net/socket.h">https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/include/net/socket.h</a> for sockets.</p> <p>Note that we use the prj.conf option &#39;CONFIG_NET_SOCKETS_POSIX_NAMES=y&#39; to transform socket functions into tider names. i.e. zsock_socket() -&gt; socket()</p><div style="clear:both;"></div>
