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

Solution 1:

For anyone wondering what the source of the files is in Jeremy31's answer, here's an alternative method.

Download the Windows driver from Microsoft to /tmp.

http://catalog.update.microsoft.com/v7/site/ScopedViewRedirect.aspx?updateid=87a7756f-1451-45da-ba8a-55f8aa29dfee

Unpack it using cabextract:

cabextract 20662520_6c535fbfa9dca0d07ab069e8918896086e2af0a7.cab

Download and build hex2hcd:

git clone https://github.com/jessesung/hex2hcd.git
pushd hex2hcd
make
popd

Make the .hcd.

./hex2hcd/hex2hcd BCM20702A1_001.002.014.1443.1572.hex BCM20702A0-0a5c-216f.hcd

Move it to your firmware folder:

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

And reload the module:

sudo modprobe -r btusb
sudo modprobe btusb

Solution 2:

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

Solution 3:

If you are using XPS 13 9350 (2016 edition), the previous answers won't work, because you need the newest driver.

The following should make your bluetooth work properly (tested on Debian Stretch with kernel 4.6.0-1-amd64):

$ wget http://downloads.dell.com/FOLDER03272920M/1/9350_Network_Driver_XMJK7_WN32_12.0.1.720_A00.EXE
$ 7z x 9350_Network_Driver_XMJK7_WN32_12.0.1.720_A00.EXE
$ cp Win32/BCM4350C5_003.006.007.0095.1703.hex ./
$ hex2hcd BCM4350C5_003.006.007.0095.1703.hex
$ sudo mv BCM4350C5_003.006.007.0095.1703.hcd /lib/firmware/brcm/BCM-0a5c-6412.hcd

Then restart your computer and enjoy!
