How to change Bluetooth broadcast device name?

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.

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.

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 ?)

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

Adapter → Parameters

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.

You can change the name of a bluetooth remote device on your PC :

1. check the MAC adress of the device in the bluetooth settings. It looks:

   XX:XX:XX:XX:XX:XX
   

2. open the Terminal and type:

   sudo gedit /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/config/info
   

3. if it asks for the password, type it (you won't see it)

4. the gedit will open up with that file.

5. modify (only) the value corresponding to 'Name'

   Name=modified_name_as_you_like_it
   

The change will not be instantaneous !

6. Restart the service (or the PC), using the command:

   sudo service bluetooth restart
   

The default Bluetooth package (bluez) comes with a command-line utility bluetoothctl that can set/reset the broadcast name (the "controller alias").

To change the broadcast name to new-name:

bluetoothctl system-alias new-name

To remove the alias, setting the broadcast name back to your computer's name:

bluetoothctl reset-alias

This will modify the appropriate settings in /var/lib/bluetooth automatically. MakeUseOf has a nice introduction on what you can do with bluetoothctl.

On Ubuntu 20.04 you can do this from the settings.

Settings > About > Device Name

Reboot your computer for the changes to take effect.

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

In Ubuntu 20.10 look at

sudo grep Alias /var/lib/bluetooth/*/settings

edit the value Alias with

sudo gedit /var/lib/bluetooth/*/settings

For example call it [email protected]

Then call

sudo hciconfig hci0 name '[email protected]'`

No need for reboot or bluetooth restart.

Alternatively you can do this from the settings:

Settings -> Info -> Gerätename

I guess in english it is:

Settings -> About -> Device Name
