Error when scanning bluetooth device

  • Hi,
    I want to use Bluetooth in Qt. I have seen example given by Qt which scan bluetooth device ("lowenergyscanner").
    But I have an error when I start scanning :

    "Writing or reading from the device resulted in an error."

    This corresponds to QBluetoothDeviceDiscoveryAgent::InputOutputError but I don't find more information regarding this error.

    I'm under Windows 10 and Qt 5.4.2 (MinGW)

    I'm also test with Qt5.5.1, and I get :

    An unknown error has occurred

    On windows (panel control), I can scan and see my bluetooth device.

    Please take the time to search the forum a bit. I've already answered that question several times.

    As @mrjj wrote, the package is currently not providing support on Windows. However you can clone the module from and checkout the wip/win branch to test it on Windows.

  • Thank you for your answer.
