Bluetooth Example Code for Cocoa (Objective-C)
I recently went through my backups to look at this code and have posted it in case anyone wants to look at it.

Please note that if you plan on working with Bluetooth for iOS devices then you want to use the Game Kit Peer-to-Peer Connectivity API and not this code.
Let Apple know you need these by filing a bug report (enhancement request) at https://bugreport.apple.com.
