Bluetooth adapter not found since mistake

realjack · 2021-04-08 19:17:28

Hi everyone, this is my first post here,

I recently bought an Dell XPS 15 9500 with i7-10750H.
Install went very fine, all working out-of-the-box as expected, until I tried to connect bluetooth to a lousy audio receptor. It didnt connect so I supposed I missed a package.

I installed with yay 2 bad packages from AUR:

btusb-qca-0x3004
bcm20703a1-firmware

But my Bluetooth device is supposed to be on my AX1650 wifi chipset. I don't know why I installed that it's stupid. Since then, my adapter isn't even found.

I went on the wiki, install bluez and bluez-utils.
I did sudo modprobe btusb, restart systemd then bluetoothctl power on, didn't detect anything. No reboot.

rfkill list all

doesnt detect my bluetooth either.

I dont know what to do, I dont want to reinstall.

I'll post every terminal entry I did that I think are relevant.

It is weird on all forum boards I went, my laptop's supposed to have either AX1650 or AX500, depending i7 or i9 and mine is i7.

systemctl seems to be fine and up to get bluetooth

I also checked ip link at some point dont know if that's relevant to the issue:

I did modprobe btusb and modprobe bluetooth.

Here is lsmod output :

Of course following the wiki I checked for bluetoothctl :

bluetoothctl

[bluetooth]# show
No default controller available

rfkill doesnt even list my bluetooth device :

rfkill list all
0: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: no

I dont know if that is the origin of the issue but I thought maybe I forgot some packages from yay and from pacman :

yay -Qs bluez

You can start by removing unneeded packages, if not already done.

See Pacman Wiki. Yay functions same way.

I notify that this is not a commercial for using yay or other similar aur installer.

I did remove both bcm-firmware and btusb qca, but I still can't get my bluetooth device detected.

 sudo -i
[root@jack ~]# modprobe btusb
[root@jack ~]# systemctl restart bluetooth.service
[root@jack ~]# bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
quitetooth]# 
[root@jack ~]# rfkill list all
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
[root@jack ~]#

I absolutely have no idea what to do...

Perhaps this article helps. It's windows related, but tips like removing battery for a while sure apply for Linux too.
Also verify that bluetooth is enabled in BIOS settings.

rfkill list should return something.

More details at Arch Wiki Bluetooth page.

Indeed I think something is wrong wrong with usb hub because the wifi card isn't designated completly :

lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 8087:0026 Intel Corp. 
Bus 001 Device 003: ID 0bda:5510 Realtek Semiconductor Corp. Integrated_Webcam_HD
Bus 001 Device 002: ID 27c6:533c Shenzhen Goodix Technology Co.,Ltd. FingerPrint
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I checked the bios and the bluetooth is enabled. I tried disabling it, then it is dead on systemctl and I am able to enable it and start it. But still nothing in rfkill list.
I enabled it again.
I tried reinstall of linux-firmware but it still won't do it.

The article also talks about updating Bios, do you think it would be relevant ?

I can't access the battery without opening the bottom frame, I'd rather avoid that for now.

There was mentioned that if Wifi is not needed, it might be automatically disabled (power save) including bluetooth too.

I don't know it this is the situation here, but if you think it is and/or want to try, then you can try disable Wifi power management.
See this Arch Wiki page for help.
The page tells how enable the thing, but it should be easy to modify it for the opposite operation.

You might be interested of this possibly related topic too.

I found my problem, I was missing the bluez-firmware package...
I actually don't know why nor how it happened, I looked up in pacman.log but didn't find any clue.

Anyway, it is working after a reboot so problem solved.

Thank you for your help and time @euromatlox
