Pretty sure blutooth is working fine on all JB kexec ROMs. I know it works fine on Avatar and CM10.1.

I am currently using the 6/15/13 nightly and bluetooth is still cutting off on me, It works for a little while then it will just drop off and I can turn it back on. It will toggle on for a split second then turn off... I'm still waiting to see if i lose GPS again like I did on the last AOKP nightly I ran... I might give CM10.1 a try again, but I will miss my swagger...
