Thanks a lot for your feedback about this problem with Qt and Bluetooth.
Do you know any device which shows this behavior and isn't very large 
and expensive? Then we could test it ourselves.

It would be great if you could create a bug report on bugreports.qt.io 
and attach a hci snoop there. Feel free to assign it to me.
