Why is the BluetoothDiscoveryModel loading the CPU at 100%?

Question

Qt

i.e. the program hangs stupidly.
Code example:
QML:

import QtQuick 2.0
import QtBluetooth 5.3

Item {
    BluetoothDiscoveryModel {
        running: true
    }
}

and the QBluetoothDeviceDiscoveryAgent object in C++ works fine.
it looks like a bug in the library, but I'm wondering: is it just me?
(there is such code, for example, in QML Blueotooth Scanner Example )

Answer 1

loads the processor at 100% and freezes not the same thing.
if the first - then utcheka where t or a curved cycle.
