When my application runs, I can scan and see the CC2540 dev kit, but I can't connect to it. In fact, looking at a packet dump, it appears that Core Bluetooth never even attempts to connect:

Has anyone else run into problems connecting to devices (in or out of the simulator)? Any suggestions? I've posted my code below. Even a simple example is a bit long.
