RTL8822BE bluetooth not working

I have a Lenovo E495 with RTL8822BE wifi/ac adapter.

The bluetooth randomly disappeared for me.

I have installed rtw88 AUR package, that is supposed to fix realtek drivers. Using LTS 5.4 kernel.

Bluetoothctl lists no available devices

Where should i look at next?

inxi -n
Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169 
           IF: enp2s0 state: down mac: 00:2b:67:8a:fd:7a 
           IF-ID-1: wlp4s0 state: up mac: 80:30:49:79:50:c5

It seems to be that inxi -n shows that the rtl8822be can’t be found

EDIT3:
Found that it is running but has somekind of a problem with an address already being in use.

As you gave all info except your kernel version: there seems to be a bug in Realtek’s driver in recent kernel versions.

  • Please downgrade / upgrade to 5.4 LTS
  • Install this driver

That being said, this might cause your WiFi to disconnect randomly and the only solution to that is to turn off Bluetooth

:sob:

P.S. You can also swap out the Realtek hardware to another brand, but then you’ll have to install the new brand’s UEFI drivers too and that’s an even bigger nightmare…

Already tried those, nothing changed for me.

The weird thing is - my wifi is working flawlessly, but linux can’t see the wifi/bt card rtl8822be using inxi -n. So it is really weird. Can I use Intel hardware(Intel makes the wifi/ac hardware aswell as far as i know) with my ryzen 5 3500u?

EDIT:
@Fabby I might go and buy intels wifi/ac module (ax200 seems to be nice), do you have any specific posts somewhere to link why the UEFI driver updates for a new brand is a nightmare or guides how to do it?

No, I’m only on page 49 of 2706 because I was in the same situation as you and wanted to replace the brand, but am using a dongle for the moment until I get to the relevant page.
