yup hc-05 is what I used (did you see my diyec link edit in #2425?). I also made life harder on myself by changing the pin, and matching the default controller baud, instead of just plugging it in and changing the controller to 9600 for starters.
I wound up patching the controller to get the linefeeds in ansi/vt100 format, and using an android app called blueterm for initial connection. I don't quite get the master slave thing either, I guess the android or the pc is the master, i.e. it has to do with the initial pairing.
