      Description

      Steps to reproduce: Build and install bluetooth/btchat example on two Android devices (I think the server side could be any platform, I tried on windows, but I encounter an unrelated bug QTBUG-98323), pair both devices and try to connect one to the other. The error will occur on the Android client side.

      Tested on Android 10 and 11.

      QBluetoothSocket.connectToService works fine on qt 5.15.2.
