QBluetoothLocalDevice::pairingStatus always returns status unpaired

The pairingStatus method of QBluetoothLocalDevice always returns unpaired, while 'Bluetooth & devices' shows the devices as paired.

And in reality The devices are paired for a fact.

Attached Qt's lowenergey example with added two lines in device.cpp shows the issue.

QBluetoothLocalDevice bld;
    QBluetoothLocalDevice::Pairing status = bld.pairingStatus(controller->remoteAddress());
     qDebug()<<status;
