Blue tooth wont connect to ps3?

I'm not sure why but today my bluetooth won't work with my ps3 it has always worked before today is the first day. The headset turns on like normal but when I try and connect it I get a error message on my ps3 saying "a connection could not be established (8001002B)" any ideas what's wrong and how to fix it? My Internet connection if fine btw so it's not that
