The message should arrive in&nbsp;mesh_msg_handle() ( assuming you have configured the app key from the phone)&nbsp;</p> <p>And one of the call back inside simple_on_off_server.c should be called from the access layer (handle_set_cb,&nbsp;handle_get_cb,&nbsp;handle_set_unreliable_cb) if you have the correct opcode.&nbsp;</p><div style="clear:both;"></div>
