I made some headway here. I uploaded some code found on an arduino basics blogspot website.
This is what i loaded onto the arduino:
/* This project combines the code from a few different sources.

I was able to get my android to recognize the bluetooth finally. Unfortunately when it asks me to pair with a code it just get the message “unable to communicate with seeedbtslave”.
I know its a code issue now but I have no idea where to go from here. Where can I get the proper code to get this to work?
