I have a bodymedia that I have paired to the S3. It says paired, the app is reading the device just fine. But the phone is asking me every 5 seconds (no exaggeration) for a pin, whether I enter it or not, it says paired and the app still works. I have turned bluetooth on and off repeatedly. Still does this. Any suggestions? And in case this helps, I am not running any task killer apps. I mostly have stock apps on the phone. Just kindle, 2Do, chrome, soundhound, keyringand pepperplate are installed....nothing that would conflict with this app. And the phone still asks me for the pin if the app is off.
