[Solved] Bluetooth down and hciconfig hci0 up timeout

Hello,

I don't normally use bluetooth on my computer, but decided to give it a try today to get it working with my bluetooth headphones. It worked like a charm, but after I rebooted my computer I haven't been able to access my bluetooth card at all.

In particular, on boot I get this error. (The last two messages pop up at my login shell)

$ dmesg | grep Blue

[    7.844683] Bluetooth: hci0 command 0x0c03 tx timeout
[   15.838488] Bluetooth: hci0 sending initial HCI reset command failed (-110)

I've tried googling the error codes and haven't come up with anything that works. Most suggestions are to make sure the device is up. Mine says it is down, but any commands sent to bring it up timeout.

$ hciconfig -a hci0

        TX bytes:12 acl:0 sco:0 commands:4 errors:0

And when I try to bring it up:

# hciconfig hci0 up

Re: [Solved] Bluetooth down and hciconfig hci0 up timeout

The thing that gets me is that it was WORKING perfectly for a good few hours -- and now it's completely unresponsive. I'd be really happy if it would just show me some signs of life!

I also thought I'd show a couple more bits of output:

# bluetoothctl -a

[bluetooth]# show
No default controller available

and

$ hcitool dev

Re: [Solved] Bluetooth down and hciconfig hci0 up timeout

A few restarts later it started working again.

I think I need to have it completely shut off for a while instead of just doing a straight reboot.

If I shutdown my computer without first typing "power off" in bluetoothctl, I get locked out again unless I shut off and then turn on my computer again.

I'm still not 100% on whether this is the actual problem, and it seems finnicky, but I can get it to work now, which is all I was hoping for.

Re: [Solved] Bluetooth down and hciconfig hci0 up timeout

This sounds like a similar issue to my issue on Pop OS. It sometimes works, sometimes doesn't. I think it might be a hardware issue on my system, because the same thing is happening with the WiFi, and it seems to be problematic when I'm moving my laptop a-lot. Does the same thing happen with the WiFi? Are there periods of time that it works well/doesn't work at all? You could try debugging it by booting with a live Linux USB to see if it works/doesn't work there, but only assuming it used to work in the live USB/CD.

Here's some command outputs:

[bluetooth]# show
