Bluetooth refuses to work properly

avgdd · December 18, 2021, 1:25pm

Hi, since I installed EndeavourOS I have never been able to fully use my bluetooth devices (keyboard, galaxy buds+) I usually manage to pair and connect the keyboard, but every other day the connection is lost and I have to use a usb cable and restart the bluetooth service manually. When trying to connect the buds+ it is even worse, since the whole bluetooth service hangs up and I need to reboot the computer, restart the bluetooth service and pair all devices again. I am using GNOME as my DE, and the bluetooth settings menu usually shows devices that are not even available anymore as if they were connected/discoverable (Say, a tv).

Am I missing something? Why is bluetooth so flawed on this OS? I am running Ubuntu on my work machine an I have had 0 issues working with bluetooth there. Is there any guide on how to properly diagnose and fix my issues?

rfkill unblock all

It could be also an issue with dualbooting, where it stores keypair in device and if you connect on p.e. windows or other installed Linux it has the wrong key stored what makes it unable to connect…

THANK YOU!!

joekamprad · March 8, 2022, 10:03pm

Welcome

Skynet · March 13, 2022, 7:44am

i have similar issue too. The bluetooth service seems to be running just fine but it doesn’t connect to the bluetooth device (earphone in my case)

first I ran the blutoothctl command
which returned the following prompt

Agent registered
[CHG] Controller 48:E7:DA:55:F3:30 Pairable: yes

then I ran the ** scan on ** command

Failed to start discovery: org.bluez.Error.NotReady

then I ran the following

sudo rfkill block bluetooth
sudo rfkill unblock bluetooth
sudo rfkill restart bluetooth

but to no avail. It seems like Bluetooth is work but not detecting the hardware.
Further more I cannot see the bluetooth option ins setting menu either

ricklinux · March 13, 2022, 8:48am

In order to help anyone with bluetooth is needed a lot of information to go through all the steps. Sometimes you have to remove everything and start from the beginning.

joekamprad · March 13, 2022, 12:58pm

sudo dmesg | grep firmware
could show some firmeware issue with the specific device.
But

org.bluez.Error.NotReady

indicates in most cases a not fully initialized device happens after freshly setup BT without a reboot ?

avgdd · March 14, 2022, 9:23am

I used a Bluetooth dongle and disabled the included the connection of my motherboard and got the same exact results. I boot to the latest ISO live environment but I couldn’t not find any GUI to play around with Bluetooth so I tried the same using a different distro.

Zorin OS did have bluetooth settings on the live environment and I was able to test that, in fact, my bluetooth was working just fine. For the moment I will be switching distros since I don’t have the time or expertise to be diagnosing the Bluetooth and GPU issues I was having.

I really enjoy EndeavourOS and I hope to be able to come back in the future

joekamprad · March 14, 2022, 11:25am

BT is not enabled per default … not on the liveI-SO and not on installed system.

But last posts was answering @Skynet also…

fbodymechanic · March 14, 2022, 11:37am

Everyone has their reasons for why they choose to use the distro they do. No worries and good luck with Zorin.

Skynet · March 14, 2022, 11:43am

I found my sweetspot in Endeavour after hopping atleast 30 distros. My latest was Arco which was great but I found it have too many packages most of which I had not clue so for my use case it was bloat.

Bravo ! thanks for response. It came out well. I did get through and got it connected. thanks again

Skynet · March 14, 2022, 12:21pm

Thanks rick. Sharing that linked saved me. after reading it , I ran the install again and got the Bluetooth connected this time. I guess I was expecting some sort of a gui tool, but this was much better and cleaner and loved it !

Great community ! Let me know if I can be of help in anyway

joekamprad · March 14, 2022, 12:25pm

pair and connect are needed also
and they are GUI tools also like blueberry for gtk or blueman and bluedevil for qt environments:

But it is a known workaround to initialize an BT audio device that was snot working using GUI with bluetoothctl as root or using sudo.
After going this cli cycle ---> scan on ---> pair --> trust --> connect
you should be able to use GUI app fitting your environment.

Skynet · March 14, 2022, 12:42pm

I think i did pair and trust
i wanna try blueman and bluedevil next

I presume the same steps apply for pairing another bluetooth device. hope there would be no conflict

@joekamprad @ricklinux
Hi Folks, I had a followup question. This may sound dumb but just stay with me. I got my Bluetooth connected after following the above instruction, however it seems to be dropping every time I reboot the system.

I had to the run the following commands (yes I read the manual) to get it up and running and connected every time.

bluetoothctl, power on, devices, connect, pair, trust

Screenshot_20220314_202044

Do I need to run these command every time ? Is this suppose to be a one time activity ? Right now it is showing my volume connections tab but when i reboot it goes away

Screenshot_20220314_203147

headset (OPPO enco M31)

Further it doesn’t show in my systems menu either ( which I presume could be because I am installing bluetooth via command line and not using the aforementioned gui tools aka blueman and bluedevil

idk…Please help.

joekamprad · March 14, 2022, 3:58pm

is BT service enabled?
systemctl status bluetooth

Skynet · March 15, 2022, 10:59am

Yes everything seems to be fine.

joekamprad · March 15, 2022, 11:07am

i think if you do not want to use GUI app you will need to save profile manually?

Skynet · March 15, 2022, 11:33am

Yes you are right. I think that was the case. I installed bluedevil and now it is it connecting. The profile was not getting saved, thus I had to run the process again every time after reboot

if one were to save the profile where would that be ? /etc/bluetooth.config ??
