Hi there,
Sorry for the late response. You were right, I didn't shut down properly my Bluetooth daemon. The scanning works even I don't set the policy related to device's Manager. Thanks for the tip about how to enable the verbose debugging. This will ease my work a lot :-). Probably it is not a good idea to make a downgrade of a BlueZ from 5.X to 4.X. There are a lot of things which can go wrong. For further tests I will create a separate environment. Best wishes, Claudiu _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
