So I dug back through LOS commits for the nougat/cm-14.1 branches, and I found a couple of commits from 2/8 that have to deal with bluetooth, specifically they changed the way bluetooth firmware is shared among hlte variants. I have pulled those commits into AOKP, and the next build, which should run on 4/10, will have them. Hopefully that will get bluetooth back up and going for you guys. I would do a test build, but I haven't had the full nougat tree on my box for quite some time now. Hopefully my build server will be up and running soon, which will let me have more storage for multiple trees and branches. Again, no guarantees on continued hlte support, but I will do what I can.
Once the new build posts to the AOKP site, test it out and let me know how it goes.
