Bluetooth Discovery Issues | Arch Linux Community | Page 1

Hello! My Bluetooth setup appears to be correct but I cant get it to discover any devices at all, whether through blueman, bluetuith, or the terminal itself with bluetoothctrl. I am fairly new to Linux, but I followed the wiki and multiple Reddit and YouTube post for the past couple days and I feel like I have wasted so much time on something so simple. for context I am trying to Bluetooth audio devices. Thank you to anyone in advance for trying to help!

Hardware: I have WiFi and Bluetooth built in to my computer. but I am using Ethernet. I have not setup WiFi.
Software: for what it is worth I am using Hyprland, that shouldn't have anything to do with it, but just in the past few days of being a Linux user it has affected more then I would think.

Here is what I have done:
Installed: Bluez, Bluez-utils, Bluez-deprecated-tools, Bluetuith, Bluedevil, and previously blueman.

Commands I have executed and their respective outputs:

I: bluetoothctl power on
O: hci0 new_settings: powered bondable ssp br/edr le secure-conn cis-central cis-peripheral iso-broadcaster sync-receiver
I: bluetoothctl
O: Agent registered
[CHG] Controller MAC ADDRESS Pairable: yes
I: agent on
O: Agent is already registered
I: scan on
O: SetDiscoveryFilter success
Discovery Started
[CHG] Controller MAC ADDRESS Discovering: yes

Then I believe it should show devices, but it shows none, I have tested it with multiple devices, and I see them on my phone.

Other things I have tried are:

systemctl status bluetooth.service
Which shows me that it is enabled, the preset is disabled, and that it is active (running).
typing devices after discovering, which shows nothing.
sudo btmgm le on which didn't seem to work.
sudo rfkill which doesn't change anything, and it wasn't locked in the first place.
sudo systemctl restart bluetooth I tried a couple times, but didn't seem to make an impact.

Thank you again in advance.

when running sudo dmesg , do you see text like the following?

[    2.812670] Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi

Sorry for the delayed response I was betting on discord notifications.
No I do not see it in there. although the logs are really long so maybe I overlooked it.

No, I went through it a couple times and I don't see it.

Without more information, seems like the driver isn't loading. Do you know the vendor for the bluetooth device?

wheat sable Jan 9, 2025, 1:31 AM

#

The motherboard is AMD.

lean raptor Jan 9, 2025, 1:32 AM

#

can you paste the output of lspci

wheat sable Jan 9, 2025, 1:32 AM

#

That command was not found for me.

#

Sorry. I was putting an I.

do you have a package manager for AUR?

wheat sable Jan 9, 2025, 1:55 AM

#

Yes, although I am unfamilliar with the name. I got it on accident. it is yay. I know how to use it though. I have frequently.

lean raptor Jan 9, 2025, 1:55 AM

#

I think this package may install the missing drivers for your bluetooth https://aur.archlinux.org/packages/realtek-firmware

wheat sable Jan 9, 2025, 1:56 AM

#

would the command be yay -S realtek-firmware ?

lean raptor Jan 9, 2025, 1:56 AM

#

yes

wheat sable Jan 9, 2025, 2:00 AM

#

It doesn't appear to have fixed the issue. while downloading the package, I go multiple errors about firmware, could that be related or no?

Thank you for helping by the way.

lean raptor Jan 9, 2025, 2:01 AM

#

There is a notice somewhere, I don't have the link on hand, about the warnings. Some of those are safe to ignore. The rest are missing drivers

wheat sable Jan 9, 2025, 2:01 AM

#

Alright. is there anything else that could be causing it? or anything else I could try?

lean raptor Jan 9, 2025, 2:03 AM

#

You can try loading the driver, modprobe rtk_btusb or try restarting so that the driver loads during startup

wheat sable Jan 9, 2025, 2:04 AM

#

Maybe you are on to something, it resulted in this:

modprobe: FATAL: Module rtk_btusb not found in directory /lib/modules/6.12.8-arch1-1

lean raptor Jan 9, 2025, 2:06 AM

Lets see if we can find the specific model for your bluetooth, try sudo dmesg | grep -i 'rtl'

Thank You, I actually just seen that too.

Okay, I might just be dumb. I got the manual out and the motherboard is ASUS PRIME Z790-V AX if that helps.

mysticalone received a thank you cookie!

lean raptor Jan 9, 2025, 2:17 AM

#

Yeah, let me see what I can find

#

It's definitely a Realtek bluetooth device. Can't find specifics. Do you know if the wifi works?

wheat sable Jan 9, 2025, 2:23 AM

#

I have yet to even try the wifi, I probably should. Although I know nothing about it. Can I easily switch back to ethernet?

lean raptor Jan 9, 2025, 2:24 AM

#

I'm not certain. I'm using gnome control panel, and I'm able to turn on/off the wifi from t here

#

it doesn't affect my current connection when I turn it on

wheat sable Jan 9, 2025, 2:25 AM

#

I just found this website while figuring out how to work wifi. Could the wifi and bluetooth use the same drivers?

#

https://wireless.docs.kernel.org/en/latest/en/users/drivers.html

lean raptor Jan 9, 2025, 2:26 AM

#

Sorry, I don't know enough to say for certain.

wheat sable Jan 9, 2025, 2:27 AM

#

I mean I probably need them anyway for wifi. Do you know which one I need by chance?

#

I just Ctrl + f for "real"

lean raptor Jan 9, 2025, 2:27 AM

#

I didn't see the model in the lspci output

wheat sable Jan 9, 2025, 2:28 AM

#

would it be PCI?

when I look it up it looks like a lot of people have issues with it and linux

#

having the exact problem I am.

lean raptor Jan 9, 2025, 2:38 AM

#

Installing linux-lts might get the bluetooth working as a last resort, I believe it installs a different kernel. It may conflict with how you have installed Arch. I know it's possible to have multiple kernels installed and referenced in the bootloader but I don't have experience with that setup. Maybe someone else could assist with that if you decide to try linux-lts. Again, not a sure bet it would get the bluetooth working.

wheat sable Jan 9, 2025, 2:39 AM

#

Alright, I am fairly new to linux, would all of my stuff still be here? or would I need to transfer it?

#

If I switched kernels*
