I am able to see other devices but some of my devices are not showing up while scanning.
Regardless of the device I try to connect to, I immediately get an error "failed to connect"
Some devices seem to be working in spite of the connection failure. As an example, I was able to transfer a picture from my computer to my phone over bluetooth even though it keeps failing to connect.
I am not getting any functionality out of audio devices.
What I did to set up BT initially:
$ sudo pacman -S bluez
$ sudo pacman -S bluez-utils
$ sudo pacman -S bluedevil
$ sudo systemctl start bluetooth.serviceLast edited by Jotunn (2024-03-13 03:56:12)

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
https://wiki.archlinux.org/title/Blueto … leshooting
From the vague symptoms: do you have a parallel windows isntallation?
Online
I am not running Windows parallel. Arch is the only OS installed on the system.
The generic Bluetooth driver is the btusb kernel module
and when I check loaded modules I get this output:
$ lsmod | grep btusb
btusb 81920 0
btrtl 28672 1 btusb
btbcm 24576 1 btusb
btintel 57344 1 btusb
btmtk 12288 1 btusb
bluetooth 1110016 40 btrtl,btmtk,btintel,btbcm,bnep,btusb,rfcommwhich I think is a good thing
unless that 0 means it is off?
but if I run
$ modprobe btusb then rerun lsmod I get the same output.
Maybe I need a different BT driver?
Offline
"0" means there're no users (userspace processes or kernel modules)
Try to pair a device and post the entire bluetoothctl session, https://wiki.archlinux.org/title/Bluetooth#Pairing
Do you use a 2.4GHz wifi connection or other 2.4GHz consumers (wireless mouse etc)?

Sorry for the delay! Here is the output from trying to pair a device:
$ modprobe btusb
$ sudo systemctl start bluetooth.service

The computer is on ethernet and has no other wireless devices connected but I believe the bluetooth transponder is functioning as part of the wifi card that came attached to the motherboard. This is why I suspected it might be a driver-related issue.

[bluetooth]# I noticed that the status always reports connected for a moment before re-reporting no. IDK if that is normal or not.

I just ran everything back and it works now!
I'm not sure if a system update fixed it somewhere along the way of if the issue was with my devices all along and my PC was fine from the first.
Either way, it works now so I am marking the thread as resolved.
Thanks again for the help Seth!
