Ubuntu Need Help - Change Bluetooth Device Name permanently - Ubuntu 15.10

[vissha]

Hi All,

I came across this old method for changing Bluetooth device name in ubuntu. It is better than creating a new file suggested in askubuntu. However, there are some issues I'm facing while trying on one of my friend's device. Could some linux users/devs help?

It says permission denied while trying to edit bluetooth config file for making permanent changes to bluetooth device name:

Note: I've modified bluetooth address to XX for anonymity in the code below.

cat /var/lib/bluetooth/XX\:XX\:XX\:XX\:XX\:XX/configcat: /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/config: Permission denied

Pls help!

This answer is based on this blog post. It worked for me. In a very Linux-y style of doing things, it's based on editing configuration files rather than using a tool.

You need to edit two files:

• In /var/lib/bluetooth/[your MAC address]/config, edit the line that starts with name.

• In /etc/bluetooth/main.conf change the line with Name = %h-%d so that it reads only Name = %h, assuming you want to use your hostname as your bluetooth name (the %d adds a different index for each local bluetooth adapter, but you probably only have one). Using something else should work, but I haven't tried that myself.

Once you're done, restart the bluetooth service:

$ sudo service bluetooth restart

Also found this... seems to be different methods for doing two very different things...

I was trying to change the default bluetooth name for my new installation of Ubuntu (it comes with ubuntu-0) pretty ugly and not at all descriptive. So I needed to change it but even though it should be just easy as click on the top bluetooth icon and configuration. But at this moment you cant so I found a solution that worked for me.

To do that you just need to create a file called machine-info into the /etc directory and set the property PRETTY_HOSTNAME.

Open the new file or edit it if it exists

sudo nano /etc/machine-info

Copy this into the file

PRETTY_HOSTNAME=MYBLUETOOTHNAME

Save it with CTRL + X and Yes.

Now just restart the bluetooth service

sudo service bluetooth restart

How to proceed with editing the /var/lib/bluetooth/[your MAC address]/config file?

In Ubuntu 15.10, when used "cat", it says permission denied. However, I've used it in many times 14.04 and it was opening.

When used "sudo nano" it was a new file and empty. Also tried "sudo gedit" and it opened as empty one.

My frnd did not want to opt for second method and I too agree. That is the reason I mentioned in my first post.
