I would take a look at <a href="https://devzone.nordicsemi.com/f/nordic-q-a/38530/relay-of-mesh-sdk-v2-2-0">this case</a> if I were you. I would add some logging to the handle_config_relay_set function to see if the p_pdu-&gt;relay_state is set to CONFIG_RELAY_STATESUPPORTED_ENABLED or CONFIG_RELAY_STATE_UNSUPPORTED.</p><div style="clear:both;"></div>
