Bluetooth is enabled and installed but no devices are shown

[chrome gulch]

I installed linux mint recently and everything else works perfectly fine but I can't get my headphones connected because nothing ever shows up on the bluetooth menu. If anyone could help that would be amazing

[swift briar]

Sorry for the stupid question but you pressed "Search" button on the left top corner, right? I almost forgot doing it myself last time lol

[chrome gulch]

yes, still nothing :/

I tried turning on "temporarily visible" in the menu because I read it might help on the forums but also nothing

[half barn]

this also happens to me. I suspect it might be an issue of kernel being too old. will test in a while.

[half barn]

@chrome gulch upon upgrading to 6.10, it magically works

you might be able to get the module on 6.8, don't know how to tho

my dongle is some cheap Baseus btw

[chrome gulch]

yeah I'm on kernel 6.8 and it's built into my motherboard

[half barn]

and am pretty sure for me, it's unsupported on earlier kernels

[half barn]

might not be the solution for you, but worth a try

[chrome gulch]

are you saying to downgrade my kernel?

[half barn]

upgrade.

1. make a timeshift snapshot
   2. apt install wget wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh chmod +x ubuntu-mainline-kernel.sh sudo mv ubuntu-mainline-kernel.sh /usr/local/bin/
2. wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/UbuntuMainlineKernel.desktop
   mv UbuntuMainlineKernel.desktop ~/.config/autostart/
3. ubuntu-mainline-kernel.sh -i

Type: hciconfig -a
To check your Bluetooth device is work or not.

tell me the results, show me some screenshots

Do that in terminal

hciconfig -a

i might help you later

Sometimes the hci0 is down

[chrome gulch]

~$ hciconfig -a hci0: Type: Primary Bus: USB BD Address: 1C:CE:51:87:13:E9 ACL MTU: 1021:8 SCO MTU: 255:12 DOWN RX bytes:736 acl:0 sco:0 events:49 errors:0 TX bytes:485 acl:0 sco:0 commands:49 errors:0 Features: 0xff 0xff 0xff 0xfe 0xdb 0xfd 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: PERIPHERAL ACCEPT

[lyric girder]

I see, hci0 is down.

So wait for sec

I will gave you an command to turn on

@chrome gulch in terminal try type: sudo hciconfig -a hci0 up

Then turn on your headphones Bluetooth and connect it using blueman-manager

[chrome gulch]

still nothing I'm afraid

it says UP RUNNING PSCAN ISCAN so I'm not sure what the problem is

[lyric girder]

Now is "up" it mean. Did you ever try to connect your headphones

[chrome gulch]

Yes

[lyric girder]

It work?

It Can be found in blueman-manager?

[lyric girder]

Simply answer is your hci0 aka Bluetooth hardware was down.

That's the problem

No your hardware is fine. Nothing faults

Hci0 just down it mean you need to turn on

Now is "up"

[chrome gulch]

When I ran hciconfig -a it said UP RUNNING so I assume it isn't down but when I hit search in the Bluetooth menu while my headphones were pairing nothing shows

[lyric girder]

Try test playing audio

[chrome gulch]

It does not show up so I can't connect it to play audio

[lyric girder]

Alright I think your headphones Bluetooth having problem.

Ever you try to the headphones connect using other devices like phone?

[chrome gulch]

They work fine with every other device I try

Yes

[lyric girder]

So I confirm it the hci0 is cannot receive or too slow receive for frequency from your Bluetooth headphones.

Do you have Bluetooth dongle?

Umm this Bluetooth dongle it work receiving frequency from headphones Bluetooth or other devices.

If the hci0 doesn't detecting your Bluetooth headphone. buy Bluetooth dongle as replacement

[half barn]

@chrome gulch what exact is your Bluetooth model?

[chrome gulch]

Sorry, how would I find this?

[half barn]

lsusb

[chrome gulch]

Bus 001 Device 007: ID 13d3:3600 IMC Networks Bluetooth Radio

[half barn]

What's your motherboard model? sudo lshw -C baseboard

[chrome gulch]

ASUS Z790-V Prime

[half barn]

apparently, for this exact model, blueman should work.

1. create a timeshift snapshot
2. install blueman from the software manager or cli
3. sudo systemctl enable --now bluetooth
4. see if it works in blueman app

btw, before this, maybe open driver manager and see if it says anything @chrome gulch

[chrome gulch]

still nothing

no drivers show up either

[half barn]

can you give me a screenshot from the blueman app?

[half barn]

it says searching and seems to be sending/receiving stuff. enable Bluetooth on your phone or your Bluetooth device and try it

[half barn]

here, it didn't do anything

[chrome gulch]

do you mean try to connect my headphones to my phone because that has always worked

[half barn]

No

it seems like it's trying to detect something. but it isn't seeing anything. are you sure your devices are on? and enable Bluetooth on your phone so that it may detect your phone, it it does then you're good

[chrome gulch]

still nothing

[spark mirage]

click view devices without a names

[rocky glen]

Perhaps a silly question, but: Did you check in Driver Manager if there is something listed?

[chrome gulch]

still not seeing anything :/

[chrome gulch]

yes, nothing there related to bluetooth or wireless connectivity

[rocky glen]

Is anything in there? If so, what?

[chrome gulch]

just gpu drivers

[rocky glen]

Should not affect it, you are right.

Can you get us the output of inxi -Nxxxz to list your network devices?

[half barn]

show screenshot

[chrome gulch]

[half barn]

oof

[rocky glen]

So now we need to figure out why the device running on the rtw89_8851be driver is not seeing your peripherals.

Damn. This brings up a repo by Larry Finger: https://github.com/lwfinger/rtw89
THAT Larry Finger: https://arstechnica.com/gadgets/2024/06/larry-finger-linux-wireless-hero-was-a-persistent-patient-coder-and-mentor/
He was a gentleman and a scholar.

[spark mirage]

real heroes among us

[rocky glen]

So short answer: Your Wi-Fi device is spanking new, and the drivers for it are not really mature yet. And with Larry not around any more to expedite the process, you are stuck hunting down somebody's homebrew driver to get it to work.

There is still a chance that you did not switch it to the correct mode to detect the devices, but my guess is incomplete driver.

[spark mirage]

could you check out what do you have in bios options? what about secureboot?

[rocky glen]

Good point, that can also block non-free drivers. But I am not sure if there are non-free elements in play here.

[chrome gulch]

I should have secure boot disabled, and fast startup turned off. Is there anything else I should check?

[spark mirage]

check out connectivity , i mean bluetooth etc

is there any options related to that ?

[chrome gulch]

All I'm seeing is a simple "enabled or disable" toggle

[half barn]

can you perhaps try the s76 kernel? might not do anything but worth a shot I guess

[chrome gulch]

is there anything else I can do?

[half barn]

not that I can think of. and you arent losing anything

[chrome gulch]

I mean I'd like to connect controllers to my computer, also the only other headphones I have are cheap earbuds where only one ear works :/

[spark mirage]

i think curunir were right, your only option is usb bluetooth dongle

at least for now

[half barn]

I meant as in you can try the edge kernel, because you aren't losing anything and it's just 3 commands. but ye as said above, may be easier to get a dongle
