BLE MESH Light Switch Delay in getting data between client and server sending to a group addresshttps://devzone.nordicsemi.com/f/nordic-q-a/47244/ble-mesh-light-switch-delay-in-getting-data-between-client-and-server-sending-to-a-group-addressHi, I am currently using two nRF52832 SDK boards to implement text message exchange with another nRF52832 SDK board via BLE Mesh SDK 3.1.0 and nRF5_SDK_15.2.0. the data i get from the UART. The problem i have with the mesh is that when i senden-USTelligent Community 13Tue, 14 May 2019 13:13:54 GMTRE: BLE MESH Light Switch Delay in getting data between client and server sending to a group addresshttps://devzone.nordicsemi.com/thread/186989?ContentTypeID=1Tue, 14 May 2019 13:13:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f96e847-34de-48c5-a6cc-5c2acff0ab4aHung Bui<p>Hi,&nbsp;</p> <p>I would suggest to&nbsp;test using&nbsp;<strong>generic_onoff_client_set_unack()&nbsp;</strong>instead of&nbsp;<strong>generic_onoff_client_set() </strong>just to&nbsp;be sure it&#39;s not the response being propagated and can cause network congestion.</p> <p>You can try&nbsp; init the log module to print out debug level to find when your message actually sent and when it&#39;s received on access layer:&nbsp;</p> <p>&nbsp; &nbsp; __LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS | LOG_SRC_BEARER, LOG_LEVEL_DBG1, LOG_CALLBACK_DEFAULT);</p> <p>The log &quot;TX:&quot; will be printed out when the message is being sent and &quot;RX:&quot; will be printed when a packet being received.&nbsp;</p> <p>Do you see the same thing with unmodified light switch example ?&nbsp;</p><div style="clear:both;"></div>
