Just wanted to add my $.02 to this thread for those of you who had the --------- as your Bluetooth version.  You "have to" download the Bluetoooth  file "separately" in the Bluetooth settings where it says update firmware.  It did not work for me the first time as there was no option to upgrade my Bluetooth in the settings and I almost gave up.  But I decided to try one more time, and holy crap it worked!!  My Bluetooth is finally working again after over a year without it......
