      Description

      I'm currently testing the new Bluetooth implemention for Windows 10 desktop applications by using your Bluetooth Low Energy Example.

      Bluetooth device discovery on Windows doesn't really perform a device discovery, but lists all (manually) paired devices instead (see QTBUG-58660). Now it can happen that some of the just "discovered" devices have been paired some time ago and are currently not available (device turned off, out of reach or something similiar). When trying to connect to such a device, the application crashes, see attached screenshot.

      Please note that a fix for QTBUG-58660 would minimize the impact of the issue descibed above too, and I would appreciate a fix for QTBUG-58660 very much.

      Edit: Happens also for UWP-Apps.

      Edit: Happens also for Qt 5.9.2.
