I am no expert but there doesn't seem to be any experts helping out. So I may have this all wrong but here is what I have figured out so far:

1. QT has a module in progress for bluetooth connections but it is not complete and is not part of the stuff that is supposed to be delivered by years end.

2. You can establish an RFComm channel and connection through DBUS interactions But I have not been able to locate any C++ examples that make sense to me.

The way I am solving the problem for my own personal use is to use the Queen Beecon widget to create a desktop shortcut for the command line "rfcomm bind" command. It is not a good solution to deploy to other people but if you have one or two devices you want to play with like me, it will let you develop the rest of your application while you wait for other solutions.
