As many others, I am having difficulty getting my bluetooth to work in Ubuntu 16.04 on my Dell XPS13.

What I've tried so far:

  1. Set Autoenable=true (https://askubuntu.com/a/808114/645176)
  2. Install some firmware (https://askubuntu.com/a/613622/645176)
  3. Install Bluez and try to use that manager

After these steps somehow I figured to not make the bluetooth device even start now...

Info on my device:

Rfkill list

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Dmesg grep blue

Any tips? Cheers.

I was troubleshooting this for a while on my Dell XPS 13 with Ubuntu 16.04, and will tell you the shortened version of some answers in these steps that worked for me. Bluetooth Broadcom 43142 isn't working

List your usb devices

lsusb 

shows this on my laptop for Bluetooth

Bus 002 Device 002: ID 0a5c:216f Broadcom Corp. BCM20702A0 Bluetooth

Go to the following Github page and download the already converted driver that matches your ID: https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm (mine was BCM20702A1-0a5c-216f.hcd) Click on the file name, then click the Download button.

Copy your file to /lib/firmware/brcm, for example:

sudo cp BCM20702A1-0a5c-216f.hcd /lib/firmware/brcm

Reboot.

That is the simplest method for what it took to get my bluetooth working correctly on Dell XPS 13, headsets and other devices all were able to connect after that.

  • Don't know why this doesn't have more upvotes. This is 100% the correct way of doing it and it is fast too. Last time I had to do this, it took me hours. This took two minutes. – Astrid Aug 1 '17 at 11:30
  • Thank you so much! You saved my day. This answer should be accepted as a solution. – Sergii P Nov 26 '17 at 11:29
  • This saved my day! Oh wait, it's midnight already.. – Christoph Bühler Feb 21 '18 at 22:58
  • Yeeeeees! However I couldn't find the driver for XPS13 2015 on mentioned github repository. Found it here though! github.com/hg8/bluetooth-firmware-XPS13-9343 – blint Mar 4 '18 at 18:51

Great advice! Thank you. Let me just provide a detail tweak that others may also find useful. In my case I was having problems (stutter) in playing sound through a bluetooth JBL Go from my XPS 13 9350 on Ubuntu 16.04.

After the operations indicated by phandolin the problem remained. The lsusb command provided this information:

Bus 001 Device 002: ID 0a5c:6412 Broadcom Corp.

However the command

dmesg | grep Blue

showed an error

[ 2.741102] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6412.hcd not found

I noticed that the name of the downloaded file needed to be changed. Therefore (in my case) I just renamed the downloaded file from

BCM4350C5-0a5c-6412.hcd

to

BCM-0a5c-6412.hcd

reboot et voilá! No more error in dmesg. Just to be sure I removed the paired device, paired it again and it's working ever since.

  • I had been trying to get BT working for so long, this finally worked. Thank you!!! – Fiver Feb 11 '18 at 18:15
