I&#39;m trying to create a joiner that will send multiple requests of joining to a thread network in order to work as a &quot;fake joiner&quot; . I would like that it will try different pskd while the commissing process is still on going. The use of otJoinerStart()&nbsp; seem necessary for me because from the code i saw that&#39;s how joiner sends his client hello to the commissioner, that&#39;s why i&#39;m trying to use it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/419048?ContentTypeID=1Tue, 04 Apr 2023 12:12:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2458cdf-8bd5-402e-8d96-fffefa7b70d2Sigurd Hellesvik<p>Hi,</p> <p>I created an <a href="https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/openthread_samples/autojoin">automatic joiner</a> sample some time ago.</p> <p>Try it out and see if it is what you need.</p> <p>Regards,<br />Sigurd Hellesvik</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/419015?ContentTypeID=1Tue, 04 Apr 2023 10:37:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dfe3ea0f-7861-47d5-a930-4947eb729aa2DavideHome<p>I would like to press the button to initiate the joining process instead of opening the CLI and write &quot;joiner start PSKd&quot; .
