Sigehere

Hello friends,
I am new in qt development. But any buddy know how can we use bluetooth device from qt project.
I want some following things:

Discovere other bluetooth device.
read and write data to bluetooth device.

Bluetooth is currently not possible with Qt.
(AFAIK only with Qt4 on Symbian devices)

You will need to use a 3rd party library.

Note: there is a "QtBluetooth module":https://qt.gitorious.org/qt/qtconnectivity, but it is not part of official Qt5 releases since they are not ready for productive usage.
