I just started working with the Starter Kit intending to use Bluetooth. I went through all the steps you described and wound up here looking for guidance a few days ago.
I did some poking around in the TI Linux microSD card with BB distro, because the BT demo on that card does pair and connect to the data source I will be using. It's always great to have a working example to start from.
So I looked through the /usr/bin and /usr/lib dirs on that card. There are Qt libraries, but none of the expected Qt-Mobility libraries (like libQtConnectivityE.so).
I copied /usr/bin/bt-* to my own target fs test ran several of them. Eventually it became clear that the BT was not through Qt Mobility. I've already forgotten how, but chasing threads I wound up here:

These instructions are written for any platform, but the detailed examples assume you are building for the AM335x target. From a quick read, I think this is how it was done for the starter kit BT demo.
