A story about changing the master name of BlueZ

I want to change the name of Bluetooth on Linux

I built my first home-built PC with Corona, what do you guys do with your host name? If it is made by a manufacturer, it has a fixed name, if it is Windows, it is random alphanumeric characters by default, if it is Fedora, openSUSE, it is localhost, or if it is Ubuntu system, it is decided by yourself at the time of installation etc .. It's a hassle to run multiple laptops, desktops and Linux and get a name, so I wanted to change it, so I got stuck.

This environment

--Homebrew PC

• openSUSE Tumbleweed
• GNOME desktop

It seems that it is separated from the host name ..

I changed the host name with the YaST tool and confirmed the change on the terminal, but it did not change even when I looked into the Bluetooth setting screen, so it did not seem to change it together. So when I tried to open hciconfig, it was gone.

hcitool and hciconfig are not included in BlueZ

Then what is the alternative?

If it is deprecated, I do not feel like using it, so there will be a change in BlueZ itself, if you look at help

    [bluetooth]# help

By discovering those things, I immediately

[bluetooth]# system-alias hogehoge

The identification name has also changed properly.
