I changed wireless card in my Asus EB1505 to Atheros AR5B225 to use Bt. After some time trying to make it work I didn't made it. =(
I installed bunch of packages recommended for ath3k, installed a Bt-antenna to 'alt' pigtail of the card, set BIOS to be compatible with UEFI and other devices of such kind.
I lack of understanding of Bt-stack. =( What are other reasonable ways to enable Bt in my Ubuntu?

I know this might be a little late but to get reliable results from my bluetooth using that chipset I had to blacklist ath3k using echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf then I edited rc.local gksudo gedit /etc/rc.local and added modprobe ath3k above the last line that needs to be exit 0 then save, exit and reboot
You do need firmware so sudo apt-get install linux-firmware
There is a timing issue with ath3k and the xhci drivers that usually stop ath3k from loading firmware but by delaying ath3k from loading this way gets the job done
