Bluetooth did not work

[3omdaughh]

I had used Bluetooth several times before, but suddenly, when I wanted to use it, I found that Bluetooth did not work. I tried it with my headset, and it did not connect. I also tried it with my phone, and it did not connect. Can anybody help me?

[HowTo] Request support

Difficulty: ★☆☆☆☆ Strong of its many members, the Manjaro support forum can provide you help whenever you have an issue with your Manjaro installation. But in order to work efficiently, we shall also ask you to follow three major points. Provide context Simply signaling an issue is rarely enough to understand how it occurred. It is thus important to provide details on how it happened: Detail prior actions leading to the issue. List solutions and guides you already tried, with links when…

• If you give us information about your system, we can see what we’re talking about and make better suggestions.
• You can do this by using inxi in a terminal or in console.

sudo inxi --admin --verbosity=7 --filter --no-host --width

• Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
• Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.

3. Copy the output from inxi (including the command) and paste it into your post.

• To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.

[HowTo] Post command output and file content as formatted text

Difficulty: ★☆☆☆☆ Formatting differences Discourse – this forum’s engine – uses Markdown to format its posts, and removes “unnecessary” whitespace. Terminal commands often produce output formatted so that they are better readable by the user, taking advantage of the monospaced font used. Programming code often rely on indentation to make it more readable. Using preformatting in Markdown Markdown includes a pattern to provide preformatting when necessary. You only need to put the part to f…

Kernel: 6.5.11-1-MANJARO

Kernel 6.5 is EOL. You should replace it with another kernel and also you need to update your system.

Have you checked already all settings in the graphical system setting manager of KDE for Bluetooth settings?

[3omdaughh]

@Wollie

Kernel 6.5 is EOL

Yeah I was thinking about change it to Kernel 5.15.

@Wollie

Have you checked already all settings in the graphical system setting manager of KDE for Bluetooth settings?

No I didn’t checked anything, I am new linux user, so there is alot of things I didn’t know BTH

[Mirdarthos]

Since you’re a new Linux user, please work through this:

[Consideration] Is Manjaro the right distribution for you?

Manjaro is NOT suitable for absolute beginners No, it’s not. And we — as the helpful community members of this forum — regularly have to explain this to the newcomers. Or at least, if we get the chance, because it is not exactly unheard of that a vocal newbie throws it out there themselves in a fit of frustration — if not arrogance or entitlement, because there’s a lot of that going round as well. So why is Manjaro not a distribution for absolute beginners? 1. Manjaro is a rolling-release d…

5.15 might be good, 6.1 also, since they are both LTS, and 6.1 will be maintained for 10 years!

And with Manjaro you should not “consider” updating older software, as it seems you have. You should update whenever an update becomes available…

[3omdaughh]

now I just updated my system. So, how to change kernel I’m already installed 5.15 LTS, how to change to it

The wiki should have been your first stop:
