That will work to manually select the external adapter, but it requires a system password so it's probably not a good way for an application to switch automatically between devices. I'd like to do it from my Objective-C code. Ideally, I'd like to access the external adapter outside of the API so the internal bluetooth can remain active. All I really care about is opening a connection and getting the RSSI value.

How does one disable an internal bluetooth adapter and select an external one instead?  I have a bluetooth dongle that I want to use. When I plug it in, OS-X sometimes switches to it, but sometimes doesn't.  I'd also like to be able to switch between the internal and external adapter or multiple external adapters.  (I want to be able to use multiple adapters so I can use multiple directional bluetooth adapters.)  Primarily I'm interested in getting RSSI signal levels for proximity detection.

Ideally it would be nice if the OS-X bluetooth API supported multiple Bluetooth adapters simultaneously, but according to what I've read in the archives it doesn't.  (Seems like a poor API design decision to me.)
