    Default Bluetooth LE Monitor


    I am a newbie, trying to get data via BLE dongle in Qt. However, cannot even find the dongle device.
    If possible, could anyone tell me where I can find a Qt example like BLE device monitor, or teach me which class should I use to open a BLE dongle on PC?

    Thank you!

    I could not even find my host BLE device.
    Could anyone help me?

    Here is my code:

    QString localDeviceName;
    QBluetoothAddress dongleAddress;
    QBluetoothHostInfo dongleHostInfo;

    // Check if Bluetooth is available on this device
    QList<QBluetoothHostInfo> dongleHostInfoList = QBluetoothLocalDevice::allDevices();

    if (dongleHostInfoList.count() > 1){
    QStringList dongleNameStringList;
    for (int n=0; n<dongleHostInfoList.count(); n++){
    dongleNameStringList <<;
    // .description();//.deviceName();
    QString dongleNameString = QInputDialog::getItem(0, QString("Sen Dongle Select"), QString("Please select your BLE Dongle."), dongleNameStringList, 0, false);
    dongleAddress = (dongleNameString)).address();
    } else if(dongleHostInfoList.count() == 1){
    dongleAddress =;
    }else {
    qDebug() << QString ("No Device Detected");

    localDevice = new QBluetoothLocalDevice(dongleAddress);
