QML Bluetoothscanner Example ServiceProtocol returns -842150451

Background:

I compared the Bluetoothscanner (Widgets) and QML Bluetoothscanner Example from the Welcome Page and found a difference regarding serviceprotocol.

Problem:

The QML example returns for serviceProtocol -842115041 as shown in the image (MAC Address was removed in the image for Security).

If I add in the Widgets example the line 109  and add breakpoint as shown in the image , then for the serviceprocol RfcommProtocol(2) is returned. 

Expected Result:

The Bluetooh Qml Type should return the enum values as mentioned. I expect same behavior between CPP and QML Type. 

Hint:

I'm a beginner for QtBluetooth, means my understanding could be wrong, if yes then reject the ticket.
