Then you have to reset the node, and re-provision.</p> <p>That might be the best choice if you have several parameters, keys and addresses that needs to be changed.</p> <p>If not there are API&#39;s to change keys etc. There are also a lot of information about this already on devzone;</p> <p>See: <a href="https://devzone.nordicsemi.com/f/nordic-q-a/32760/problems-changing-network-key">https://devzone.nordicsemi.com/f/nordic-q-a/32760/problems-changing-network-key</a></p> <p>Best regards, <br />Joakim</p><div style="clear:both;"></div>
