Cannot connect Bluetooth earphones

General system Newbie

I can’t get my laptop to connect to my Baseus E16 wireless earphones. It successfully paired, then connected, but it disconnects shortly after. I tried connecting with bluetoothctl but it also failed, here is the result:

[sat@baja-coil ~]$ sudo bluetoothctl

The device connected after:

but disconnected after:

I’ve looked everywhere for a solution but none seems to work. Help would be appreciated, thank you in advance…

I would remove it from the list and rescan and re-add. Pay attention as sometimes you will get a notification asking if you if it should allow the bluetooth connection click the confirm or accept button. Make sure you trust the device.

also would be helpful if you gave us a bit of information like what DE?

Is it a dual-boot system?

I had the same problem today - haven’t used my heaset for quite some time…

Turned out it worked fine after downgrading bluez to 5.82-1

sudo pacman -U https://archive.archlinux.org/packages/b/bluez/bluez-5.82-1-x86_64.pkg.tar.zst

(see https://wiki.archlinux.org/title/Downgrading_packages#Arch_Linux_Archive)

Added bluez to the ignorepkg list in pacman.conf so it won’t upgrade to 5.83-1.
(see https://wiki.archlinux.org/title/Pacman#Skip_package_from_being_upgraded)

edit: we are not alone…

I’m using Niri WM wayland. I also tried it with KDE and the result is the same
