Need help with bluetooth please, for a game

[macmitt2300]

I've developed a rock paper scissors app but I'm trying to incorporate bluetooth so that people can play against each other, I've looked at the bluetooth chat example but it wasn't any help and my google history now has a lot of searches about bluetooth, can someone help me out with being able to send a string back and forth and making sure both players made moves before it checks which one won or not, any help is VERY much appreciated
