Ubuntu – Bluetooth not connecting to devices even though it recognizes them

bluetooth

I'm runing 15.04 on a dell xps 13
bluetooth recognises devices when i try to add them but won't let me connect to them
Here is the results from my terminal.

~ $ uname -a; lspci -nnk | grep -iA2 net; lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; lsmod | grep bluetooth

wget "https://dl.dropboxusercontent.com/s/r2pb41rhx65t9zi/BCM20702A0-0a5c-216f.hcd"
sudo cp BCM20702A0-0a5c-216f.hcd /lib/firmware/brcm/
sudo modprobe -r btusb
sudo modprobe btusb

For source of the hcd file see @Ian's answer

See if it works

For Ubuntu 15.10+ and 14.04 with kernels 4.2+ the second command should be

sudo cp BCM20702A0-0a5c-216f.hcd /lib/firmware/brcm/BCM.hcd
