I just can't figure a way to change my Bluetooth device name.

Is there any command?

You can't change bluetooth device name from control panel in ubuntu yet. Here is the bug report, which provides this workaround:

If you want to change the bluetooth device name permanently, you have to create a file called /etc/machine-info which should have the following content:

PRETTY_HOSTNAME=device-name

After this, restart the Bluetooth service:

sudo service bluetooth restart

Or reboot.

No need to restart. service bluetooth restart does the trick. – arunasr Oct 21 '14 at 15:23
    
Still working on 15.04, thanks! – phaberest Aug 17 '15 at 10:34

It seems the option was removed from the Bluetooth control panel, but you should still be able to change the name via the command line:

sudo hciconfig hci0 name 'Device Name'

Once you run the command, you should be able to verify the change by bringing up the Bluetooth control panel again and checking the device name.

This should be the accepted answer. – Naftuli Tzvi Kay Mar 27 '14 at 18:07

It works, but the name is reset after reboot. I use Ubuntu 14.04. Can it be set permanently? – BornToCode Sep 4 '14 at 2:49

As @BornToCode points out, the change doesn't persist. Restarting the service with service bluetooth restart will show that the name change is reverted. – Paul Lammertsma Jan 22 '15 at 0:40

What I did (on 12.04):

  1. device name is stored in /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/config
  2. delete it
  3. restart (~# service bluetooth restart)
  4. device name is rewritten in config (according to /etc/bluetooth/main.conf ?)

If you don't like the bluetooth version of the device name, i.e. hostname-0, you can replace the line "Name = %h – %d" to simply "Name = %h" in step 4 above, which will get rid of the numbering suffix, as I just did in 13.04. – Sadi Jul 10 '13 at 17:31
    
this works on 15.04 – Mark Jun 17 '15 at 14:27

I am using Blueman Bluetooth Manager. There is an option to change a computer's BT name in:

Adapter → Parameters

Thank you very much! This is more like the Ubuntu-way ( more user-friendly ;-) than other answers, and the latest version 1.23 has this feature via menu Adapter → Preferences → Friendly Name. Further info: github.com/blueman-project/blueman – Sadi Sep 21 '14 at 8:02

To change the bluetooth host name permanently, on Ubuntu 14.04 or later:

Open a terminal with CTRL-ALT-T

  1. Edit /etc/bluetooth/main.conf replacing "%h" with the computer name you want. "%h" always seems to represent "ubuntu" on my systems for some reason.

    gksudo gedit /etc/bluetooth/main.conf

    For example change Name = %h-%d to Name = gruber-%d `

  2. Remove /var/lib/bluetooth/xx:xx:xx:xx:xx:xx/config to make your system forget the old name. The xx:xx:xx:xx:xx:xx has a hexadecimal value unique to your bluetooth hardware.

    sudo rm /var/lib/bluetooth/xx:xx:xx:xx:xx:xx/config

  3. Restart the bluetooth service

    sudo service bluetooth restart

    (Under 15.04 or later:)

    sudo systemctl restart bluetooth.service

You can check the new name by opening the Bluetooth settings. The last two steps are from Marx's answer.

This is my preferred answer, but rather than delete the config file I would rather edit it, as in dreis nineoneone's answer. Incidentally, the service command still works in 15.04. – AFH Dec 6 '15 at 16:01

You can change the Bluetooth of your PC just by:

  1. opening the Terminal an type:

    sudo gedit /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/config
    
  2. if it asks for the password, type it (you won't see it)

  3. the gedit will open up with that file.
  4. on the line that begins with "name" replace the name itself. It will not be instantaneous! You'll have to restart the service (or the PC). Do it by typing:

    sudo service bluetooth restart
    

It worked for me.

Thank you Eric for the rearrangement. – dreis nineoneone Nov 30 '15 at 14:31

If your adapter has an alias, also edit /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/settings, and change that. – Mr. B Jun 20 at 22:30
sudo apt-get update; sudo apt-get install -y nano
sudo nano /var/lib/bluetooth/*/config
sudo service bluetooth restart

Update the value for “name”. In my case, it was: Ubuntu-0

This answer provides the same solution as many others, but with much less detail. – Zacharee1 Mar 17 at 18:12
