Please elaborate. Are you saying late 2015 6s and MBP bluetooth profile implementations are incompatible?!
Here's IOS 9.x / iPhone4 & above compatibility table: https://support.apple.com/en-us/HT204387
My 5s had no issue pairing and it has identical bluetooth services as the 6s - below.
Strangely enough the MBP does manage to enumerate those 2 devices.
