Bluetooth module not working after reinstall

I reinstalled Manjaro with the latest version yesterday with kde 6. Since then I’m not able to turn on my bluetooth to connect to anything. I use an Asus laptop, it used to work fine with older versions of Manjaro, the latest reinstall sparked this issue for me and a couple of friends.

sudo dmesg | grep -i bluetooth

Hi @plshelpme123, and welcome!

In order for us, or anyone for that matter, to be able to provide assistance, more information is necessary. To that end, please see:

Please also note and heed: Forum Rules - Manjaro

Hope you manage!

:bangbang: Tip: :bangbang:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby improving legibility and making it much easier for those trying to be of assistance.

:bangbang::bangbang: Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Please edit your post accordingly.

I found a temporary solution to this issue.
Downgrading the kernel seems to help for now. The linux69 kernel was somehow creating an issue and downgrading the kernel to linux68 helped.
I read on some arch forums that it could be fixed by creating a symlink for the file

BT_RAM_CODE_MT7961_1a_2_hdr.bin

linked to the older file

BT_RAM_CODE_MT7961_1_2_hdr.bin

This seems to have worked for others without downgrading their kernel but didnt for me. So i hope it helps anyone who is facing a similar issue.
