Method QBluetoothSocket::connectToService(QBluetoothAddress, QBluetoothUuid) seems not to work for Win 10

When trying to connect to a bluetooth service on Windows 10 by using the method

QBluetoothSocket::connectToService(QBluetoothAddress, QBluetoothUuid)

QBluetoothSocket doesn't connect and gives me an "Unknown Error". When I use instead the method

QBluetoothSocket::connectToService(const QBluetoothServiceInfo)

everything is working fine.

I could reproduce this behaviour by using the Bluetooth Chat Example: Just replace in the method ChatClient::startClient() the line

socket->connectToService(remoteService);

with something like

socket->connectToService(remoteService.device().address(), QBluetoothUuid::SerialPort);

The first statement is working, the second not. (Please note that I'm using QBluetoothUuid::SerialPort as a UUID in the second statement because I was testing to connect to a proprietrary Bluetooth device, but the issue should also occur with the original code.)
