I want to add a new Bluetooth device. But it seems like Bluetooth is disabled and nothing helps add a new device.

My system: ThinkPad T470s; Ubuntu 16.04 LTS; encrypted Hard drive (I tried it before with a non encrypted HDD and it would work fine). After I setup the system I also updated it and then restart. Now I wanted to connect a bluetooth keyboard.

Results of rfkill list:

2: tpacpi_bluetooth_sw: Bluetooth
    Soft blocked: no
    Hard blocked: no
18: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

So, I assume a Bluetooth adapter exists.

When I go to the bluetooth hardware in the system settings:

... and try to turn bluetooth on, then you can see (at the top right corner) the Bluetooth icon disappears (for some reasons):

I tried to reinstall bluez and also install blueman.

When I open the Bluetooth manager, you can see that none of the icons are clickable.

I also did this:

sudo gedit /etc/rc.local

and added the following line before exit 0

rfkill unblock bluetooth

...and then restart. Then I repeated the steps mentioned above. Same result: Cannot add new devices.

    Please edit your question and add output of lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue terminal command.

  • Due to your hint I could solve it. Thanks @Pilot6 See answer. Jun 2 '17 at 14:26

It seems like ibt-12-16.sfi was missing. I downloaded it from this site and copied it to /lib/firmware/intel

  • I see ibt-12-16.sfi in the mentioned directory location, but my visibility is still disabled any ideas? Jul 4 '20 at 8:11
