Thanks a lot for your inputs. It really helped.
I would like to know if other features like Handsfree, Phone book and Media streaming including control
are supported in Qt Bluetooth.

Thanks and Regards,
Ramakanth

Thank you for the data. The issue is that Qt 5.3.x does not support Bluez 5 yet. You have to use Qt 5.4 which added Bluez5 support.

Your Bluez output looks as expected and at least the current issue should not be one in 5.4.

I'm using Qt5.3 on 64 bit linux installed with the online installer package qt-opensource-linux-x64-1.6.0-4-online.run.

The output of querying for Bluez5 is attached.

Greetings,
Andreas
