OS 10.2.0.1047 music skips over bluetooth

Hi, with my Z10 STL100-3, the music skips every 3-4 seconds over bluetooth. It sounds like a skipping cd back in the days :)
If I listen with a wired headset, everything's fine.

I tried a bluetooth headset sony MW600 and my Sony car radio and both are doing the same thing.
I also tried to delete the bluetooth profile in both the phone and listening device.

It was doing this with latest OS 10.1 from Rogers and it's also doing the same thing over 10.2.0.1047

Any suggestions ?

Thank you
