No BLE devices discovered on windows 10.

Starting the example http://doc.qt.io/qt-5/qtbluetooth-lowenergyscanner-example.html while broadcasting with a BLE iphone app results in no devices listed.

When writing a custom app that tries to scan with:

discoveryAgent = new QBluetoothDeviceDiscoveryAgent();
discoveryAgent->setLowEnergyDiscoveryTimeout(0);
discoveryAgent->setInquiryType(QBluetoothDeviceDiscoveryAgent::GeneralUnlimitedInquiry);
connect(discoveryAgent, SIGNAL(deviceDiscovered(const QBluetoothDeviceInfo&)),
this, SLOT(addDevice(const QBluetoothDeviceInfo&)));
connect(discoveryAgent, SIGNAL(error(QBluetoothDeviceDiscoveryAgent::Error)),
this, SLOT(deviceScanError(QBluetoothDeviceDiscoveryAgent::Error)));
connect(discoveryAgent, SIGNAL(finished()), this, SLOT(deviceScanFinished()));
discoveryAgent->start(QBluetoothDeviceDiscoveryAgent::LowEnergyMethod);

still the ble device advertisements are not picked up.

If i use BluetoothLEAdvertisementWatcher in Visual Studio 2015 then advertisements are picked up, so it seems its not the problem with the BLE radio.
