https://test-devzone.nordicsemi.com/f/nordic-q-a/88902/thread-with-nrf52840dongle-without-using-the-ot-ctl-cHey, I was trying to create a python application on a linux environment to send UDP messages over thread. Do I need to use the ot-ctl cli to send udp messages? I tried to communicate using netcat and this did not work.

So you have two alternatives.</p> <p>1. Use the serial interface to control the chip. This can be done either using ot-ctl or <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_logging.html?highlight=spinel#spinel">spinel</a> for this.</p> <p>2. If you connect the thread network to the internet using a <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thread_tools.html#thread-border-router">OpenThread Border Router</a>. In this case, the devices can bet IPv6 addresses, which you can ping over the net.<br />EDIT: This alternative is not as simple as it sounds, as it requires the router to allow the Border Router to use IP addresses for all of you Thread devices. See <a href="https://openthread.io/guides/thread-primer/ipv6-addressing">OpenThread on IPv6 addressing</a> for the concepts of Thread Addressing.</p> <p>Does this answer your question?</p> <p>Regards,<br />Sigurd Hellesvik</p><div style="clear:both;"></div>
