    Description

      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.
