[kernel] bluetooth JBL 2 speakers can not connect anymore

Hi everyone,

I am on arch (5.1.15-arch1-1-ARCH stop last kernels updates because of USB lag issues) with i3wm (4.16.1-107).

I have a JBL 2 speaker working through jack and that has been working through bluetooth for several years until last kernel updates.

Everything is working fine with kernel 4.20.13 when I downgrade.
I can connect it instantly with my android phone without any PIN, so I guess the JBL 2 speaker is fine.


typical bluetoothctl behavior:

pulseaudio-bluetooth is installed.

I tried with blueman too, impossible too with connexion not available message.
I tried with python too and can not get any info about the device when I can from others.

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

Am I in the right section or should I move it somewhere else?

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

i had the same issue the other day with my jbl go , cant remember exactly what i did but im pretty sure i used bluetoothctl and used the "power off" command, then used rfkill to unblock it again, then used bluetoothctl "power on" then "scan on" and for some reason it came back to life, id been bashing my head against a wall for ages with blueman gui and getting nowhere. i possibly also rebooted in their somewhere too, sorry i cant remember exact sequence.

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

Thanks jonno2002 for the help. I did follow your steps and still get the same error:

Failed to connect: org.bluez.Error.Failed

How do you use rfkill? I did not use it in my old process.

When I run it naively I get:

ID TYPE      DEVICE      SOFT      HARD
0 bluetooth hci0   unblocked unblocked

Seems unblocked.


Every time I do that, it connects and then disconnect..

[CHG] Device XX Connected: yes
Failed to connect: org.bluez.Error.Failed
[CHG] Device XX Connected: no

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

i had to use rfkill to unblock my device after i blocked it but yours isnt blocked so thats not it.

hmmm try trusting the device before pairing with it, see if that helps.

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

I made further checks.
I downgraded my linux kernel to 4.20.13 and the bluetooth works perfectly.

So, I guess this is a kernel problem. Does someone have a patch for the current 5.x kernels? Should I report that?

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

Try the latest stable kernel, no one cares for a bug report if you can't reproduce on kernels that are still actively supported. The 5.1 kernels around that timeframe you were on were known to have bluetooth issues, AFAIK most of those should be fixed. What actual problems do you have with the 5.2 series? You're the first person I'm seeing mentioning USB lag issues.

Re: [kernel] bluetooth JBL 2 speakers can not connect anymore

Hi V1del,
Thanks for your time.

Indeed, I did have important issues with the latest kernels. I retried the latest kernel (5.2.8) and there is the system situation:
usb keyboard and mousse freeze/hang. Meaning that if I don't input any action with them for 2 seconds, then it won't do anything for the next few actions, key presses will be lost and mousse stuck for a few seconds.
This is impracticable, user experience is too bad
Otherwise, laptop keyboard and touchpad are working perfectly. The issue is only with my usb/bluetooth external keyboard and mousse

I would like to precise that I have the same issue [1] with my current "working" kernel when I resume from suspend state. The exact same issue appears in this situation. I dug on this problem and have to admit that is the biggest problem I am facing on my XPS 15 9570 for the last 6 months. Please, help me to fix that.

Thanks.
