      CSR BTC/BLE sample dongle (HCI v 4.0, revision 0x22bb, LMP v 4.0, subversion 0x22bb)

    Description

      Using both a custom application and the sample heart rate application randomly causes connection problems with this line emitted on the console:
      qt.bluetooth.bluez: void QBluetoothSocketPrivate::_q_readNotify() 12 error: -1 "Software causes connection abort"

      But no-where in the application am I calling a disconnect. The device is receiving and transmitting data when this happens (heart rate demo: receiving only, my custom application: receiving and transmitting), the time before it happening varies.
