Does anyone know of a simple script to get the signal strength of the bluetooth connection on OS X? I've been putting together pieces of this app functionality, but I'm stuck at a scriptable / command line bluetooth program. Right now I'm using a bunch of launch daemons to disable the requirement for a password when I'm on a particular wifi network, but bluetooth would be handy.
