Dear all，

We use thingy's microphone collect data and transmit to Android mobile by BLE, and need no loss of reliable data transmission.

How to do?

Thanks a lot.

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 not retransmit, this is currently not possible over BLE.
