In recent Qt versions there's support for BLE on Windows, so remove the check that disables it. In Qt 5.14.2 and earlier there's a bug which causes problem if you do certain things in the context that the signals are emitted. This is only on Windows, and might be fixed in later versions, but use Qt:QueuedConnection for now to avoid this. Some more details of this can be found in Qt bugzilla: https://bugreports.qt.io/browse/QTBUG-78488
