    Description

      The "connectToDevice()" method hangs when trying to connect to a disconnected/non-reachable device on Windows:

      void MyClass::connect()
{
	QBluetoothDeviceInfo info;
	m_controller = new QLowEnergyController(info, nullptr);
	m_controller->setRemoteAddressType(QLowEnergyController::PublicAddress);
	m_controller->connectToDevice(); // this hangs
}

      The following message is printed repeatedly in the debug output:

      qt.bluetooth.winrt: Characteristic operation failed
