HI,

 I think Bluez is a official Blue tooth stack from kernel.org, If it is the
case then it should work without any issues, just now I checked for Bluez ,
it is official which mean default all kernels downloaded from
kernel.orgwill come with bluez , so why there is a chaos in
compatibility when it
comes to android porting?
