Bluetooth - support question

Hello,
I need to connect to the device via Bluetooth and the question, is QtMobility, to be more precise QtConnectivity, able to do that? I need Bluetooth support for the Windows/Linux?MacOSX.
According to the http://doc.qt.digia.com/qtmobility-1...-compatibility (last chart) QtConnectivity don't have backend for the Windows and MacOSX.
There is also QML plugin for the QtMobility. From the read it supports only Symbian and Meego.

Has anyone was able to use QtConnectivity on the Windows/MacOSX to connect via Bluetooth?

Or maybe someone can recommend good multi-platform c/c++ library for the Bluetooth connectivity.

Regards
