When hooking up the HC-O5 bluetooth module we found one of the connections in the pinout was labeled "state". We are wondering if anyone knows where this connects to the Arduino.

We won't need that connect for using the HC-05 -- only the four pins that have metal posts on them. But, if you want to know more, have a look at http://www.martyncurrey.com/hc-05-fs-040-state-pin/
