Bluetooth suddenly stopped working

English Network/Internet
#1

Hello,
I remember using Bluetooth before on this computer, but today when I tried to connect to my phone KDE just said “No Bluetooth adapters available”. The Bluetooth logo status light on my computer has turned off (I remember it being constantly on before).

Hope some of that command output helps.

Is this after a recent update? If so, how did you update?

A bit off-topic: did you try KDEconnect? Uses you wifi network

#3

I always update using zypper dup. I don’t remember exactly when this stopped working, so I can’t say if it was right after an update. Since I am using TW, it could be the case.

I do use KDEConnect, but I was trying to do something, that KDEConnect can’t do.

#4

Mmm, installed bluez-tools but everything’s OK here. Did you also try through the KDE bluetooth service and applet?

#5

KDE settings say “No Bluetooth adapters available.”. The system tray icon says the same thing after clicking.

#6

This seems to be the same issue

Hello,

What’s the output of:

sudo systemctl status bluetooth

?

PS: Yes, I am aware of the fact, that WD Elements 1042 is a hard drive.

#9

Poke. Has anyone found out anything interesting?

#10

Does dmesg report anything re. bluetooth?


dmesg | grep -i blue
#11

I am having exactly the same problem, with exactly the same output from commands, on Leap 42.3.

#12

So, bluetooth has just started working out of nowhere. No idea how it happened.

#13

If you are using the Atheros AR3012 it seems to be a duplicate chip ID error on two different card manufacturers and which firmware is loaded. At least it was on my hardware. I’m still running the old kernel listed in the bug report below to use bluetooth.
