How to do? Thanks a lot.en-USTelligent Community 13Tue, 03 Apr 2018 13:14:40 GMTRE: We use thingy's microphone collect data and transmit to Android mobile by BLE, and need no loss of reliable data transmission.https://devzone.nordicsemi.com/thread/126659?ContentTypeID=1Tue, 03 Apr 2018 13:14:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0929e00c-211c-4a9f-b913-7d453af03fffStian R&#248;ed Hafskjold<p>Hi, not sure what you are asking here. The BLE protocol will retransmit data until everything is acknowledged by the receiver. So you will inherently have a reliable connection. If you mean the opposite, like if you want the connection to <em>not </em>retransmit, this is currently not possible over BLE.</p><div style="clear:both;"></div>
