Bluetooth not working. "No default controller available"

[Laufragor]

Done, rfkill and bluetoothctl give the same outputs as before.

Okay …i did look at the manual but the only button turns WiFi on or off and blutooth chip is on the WiFi on rtl8821ce as far as i know.

@Laufragor
I would suggest you go through the wiki here and make sure we aren’t missing something. I don’t know what desktop you are using so just want to make sure you aren’t missing a package that is needed.

Done, everything seems right I’m using Cinnamon and blueman.

Btw I found a USB bluetooth adapter that works with Linux (this), I like solving problems but troubleshooting the RTL8821CE has taken so much of my time that I feel like it’s not really worth it for me to spend more time on it.

Thanks so much for the help! But this chipset seems so problematic that I’d rather solve this problem more efficiently now haha. I saw many users change their network card lmao, I’m going for this quicker and cheaper solution.

What chip does it use?

inxi -Na

[Laufragor]

inxi -Na does not show it (it works btw!), other commands I tried show the following:

$ inxi --bluetooth
