https://devzone.nordicsemi.com/f/nordic-q-a/79985/add-children-to-a-thread-ressourceHello I am developing an application based on the &quot;ble_thread_dyn_mtd_coap_cli&quot; example. To create a Thread resource, I see that the &quot;otCoapAddResource()&quot; function is called. My question is: is it possible to create child resources with this functionen-USTelligent Community 13Fri, 24 Sep 2021 15:05:24 GMThttps://devzone.nordicsemi.com/thread/331131?ContentTypeID=1Fri, 24 Sep 2021 15:05:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9262d3a9-0b06-4652-84a1-3e761e6893eaGPereira<p>Hello QuentinD!</p> <p>Your question seems to be related to <a href="https://datatracker.ietf.org/doc/html/rfc7252">CoAP&#39;s specification</a> itself rather than an Thread related question.</p> <p>As you are probably aware, CoAP resources are defined by their path and the REST methods implemented. This architecture allows flexibility on path definition in such way that you can define a CoAP resource that listens on /led and three others that listen on /led/1, /led/2 and /led/3.</p> <p>The action you implement on a request to /led can call the three functions the other paths call. Does this solve your problem?</p> <p>As a final note I would advice against using the OpenThread&#39;s implementation of CoAP since it is not as complete and not as actively maintained as <a href="https://docs.zephyrproject.org/latest/reference/networking/coap.html">Zephyr&#39;s CoAP implementation</a>.</p><div style="clear:both;"></div>
