qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.



  • Re: Qt Bluetooth module is non-functional

    I have the issue with Bluetooth module programming.
    Application output logs "qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional."

    Trying with the example given in Qt::example===========
    QBluetoothLocalDevice localDevice;
    QString localDeviceName;

      // Check if Bluetooth is available on this device
     if (localDevice.isValid()) {
    
         qDebug()<<"Welcome to Bluetooth programming...";
    
         // Turn Bluetooth on
         localDevice.powerOn();
    
         // Read local device name
         localDeviceName = localDevice.name();
    
         qDebug()<<localDeviceName;
    
         // Make it visible to others
         localDevice.setHostMode(QBluetoothLocalDevice::HostDiscoverable);
     }
    

    ===============================================

    My Qt version : Qt 5.6.1 (MSVC 2013, 32 bit)
    OS : Windows 10
    Bluetooth module in HP Laptop (Qt program runs here) :
    Remote Device : Galaxy J2 & ASUS T00J
    QT += bluetooth (in .pro file)

    Can anyone helps me to sort the issue ?

    Thanks in advance.
