I found a command (hciconfig -a) but it didnt work for me. I got that info with bluetoothctl show:

There is a section that shows me ‘SupportedInstances: 0x05 (5)’ and if I understood clearly, it meant

5 (0x5)     | 3.0

but when I searched it from store, it tells me, I saw that my computer has bluetooth 4.2 so I wanted to be sure about this situation. Have I done this correctly?

That would be the way to find out, however that’s a deprecated tool no longer in bluez-utils. It doesn’t appear the D-Bus Device API completely replaces it yet.

The deprecated tools are only available via bluez-utils-compat from the AUR (Arch User Repository). It may not always work properly, install at your own risk.

I’m not sure what that means off hand, but I know it doesn’t mean BlueTooth 5. Mine reports 0x06 (6). That doesn’t match the HCI versioning.

I downloaded that and my output looks like;

Hmm, it doesn’t report HCI Version. Well, it is a deprecated tool. ¯\_(ツ)_/¯
