QBluetoothLocalDevice cannot find Bluetooth local device

  • Hi!
    QBluetoothLocalDevice::isValid() always returns false on computer with Windows 7 x64 and Broadcom BCM2070 Bluetooth 2.1+EDR USB Device. But Windows finds Bluetooth devices and can communicate with them.

    Qt Bluetooth examples also don`t work. I am using Qt 5.2 with MSVC 2010 x86.

    @ QBluetoothLocalDevice localDevice;
    QString localDeviceName;

    // Check if Bluetooth is available on this device
    if (localDevice.isValid()) {
        // Turn Bluetooth on
        // Read local device name
        localDeviceName =;
        qDebug()  << localDeviceName;
        // Make it visible to others
    else {
        qDebug()  << "Bluetooth is not available on this device";

    As per "this": bluetooth is supported only for Linux/Bluez 4.x and BlackBerry.
