You will receive&nbsp;<span>NRF_MESH_EVT_FRIENDSHIP_TERMINATED event when that happens.&nbsp;<br />After that you can choose to re-initialize friendship again (with other nodes) by calling mesh_lpn_friend_request(). Please have a look at&nbsp;initiate_friendship() function in our LPN example.&nbsp;<br />Note that you may need to wait for a period of time before you call&nbsp;mesh_lpn_friend_request() after you receive&nbsp;NRF_MESH_EVT_FRIENDSHIP_TERMINATED&nbsp; event. If you call it in the same event, you may receive&nbsp;NRF_ERROR_INVALID_STATE error.&nbsp;</span></p><div style="clear:both;"></div>
