I'm running Ubuntu 16.04 on Lenovo ThinkPad T470s and quite simply, bluetooth appears to not exist, even though it is clearly in the computer according to all specifications available.

It appears that I'm missing a kernel driver. Sounds easy enough: except I cannot find any information on where to find this driver or even identify which one it is. I've searched online for the specification and all I find is "integrated bluetooth" or something to that effect. The most specific I've found so far is "Intel Unknown" from an Ubuntu page. I have been unable to use this information to find any kind of Linux bluetooth driver, whether from Intel or anywhere else.

Neither lspci nor lsusb show anything useful but here is the output anyway:

So, quite frankly, I'm stuck, and I haven't been able to find anything useful online. Any tips on how to identify my bluetooth chip and/or find Linux (Ubuntu 16.04) drivers for it?

  • Not working bluetooth is mentioned as a known problem for the t470s in the german thinkpad forum; thinkpad-forum.de/threads/205438-T470s-linux/page3 They are talking about a firmware problem, Bus 001 Device 004: ID 8087:0a2b Intel Corp should be your wifi/bluetooh

This should solve your problem:

sudo apt-get install linux-generic-hwe-16.04-edge xserver-xorg-input-libinput-hwe-16.04
wget https://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161.1_all.deb
sudo dpkg -i linux-firmware_1.161.1_all.deb

Do this, and reboot.

Source? Here, people facing the same issue with the Intel 8265 Bluetooth on Ubuntu 16.04 LTS and other notebook models like Lenovo Y520 and Dell Precision 5520m.

This command line means that you will need HWE version of libinput+kernel, and a version higher than 1.161.1 of the linux-firmware package.

Got the exact bluetooth model number by browsing theSCCM Package for Windows of Lenovo t470s.

As reported by other users, this solution works with Thinkpad variants t470 and t470s

  • Thank you so much. :) I actually didn't need to install the packages in the first command, only the wget-ed one. I also downloaded it using HTTPS. Thanks again!

  • Glad it worker :) . Maybe you are already using the hwe kernel(4.8)...

  • Well, I'm using this, don't know it i's a HWE kernel: Linux tutu 4.8.0-52-generic #55~16.04.1-Ubuntu SMP Fri Apr 28 14:36:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    If you are using Ubuntu 16.04 and kernel version 4.8(instead of 4.4), you are using HWE. It is a measure that Canonical took, to give fresh kernels to it's LTS brand, specially to increase drivers on those distributions, without breaking(and without having to deal with other mirrors to install newer versions of kernel non-LTS on LTS) - wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#hwe-16.04-edge

  • That's very interesting. Thanks for the info. :) - By the way, I took the liberty to update your response so that the link is HTTPS.
