How many nodes are in your network? What does a typical node look like (amount of Mesh models on each node)?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/511937?ContentTypeID=1Mon, 25 Nov 2024 14:32:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b79382cf-ace9-4838-8d47-a251312bdd12Edvin<p>Hello,</p> <p>Did you have any logs from the nodes when the issue occurs? Preferably also the network core logs, to see if anything is happening there when the node starts acting weird.</p> <p>How long does it usually take before the issue starts to occur?</p> <p>Is there some way for me to reproduce the issue with a handful of DKs, or does it require a large test-rig?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
