[SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

Hi, I am running Arch linux on my Thinkpad x1 carbon 7th Gen and I have followed all the arch-wiki commands to install bluetooth, but when I run a list command on bluetoothctl I get a "no controllers found" error, I have noticed my bluetooth module is softlocked and I cannot seem to figure out why. sudo rfkill unblock all does not seem to work. I am not blacklisting the bluetooth module either. Here are some command outpoints.

It is not a hardware issue as I have dual booted windows on this laptop and bluetooth works on my windows machine.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

* Compare to my modules, you are missing rfcomm. Is the module blocked from loading? What happens when you load it?
* Any errors in the log following the command? How about $? ?
* What happen when you execute: echo 1 | doas tee   /sys/devices/platform/thinkpad_acpi/bluetooth_enable

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

It does not seem to exist 

➜  ~ find /lib/modules/$(uname -r) -type f -name rfcom*
zsh: no matches found: rfcom*

loading it doesnt seem to make it show up either

➜  ~ sudo modprobe rfcomm
➜  ~ find /lib/modules/$(uname -r) -type f -name rfcom*
zsh: no matches found: rfcom*
➜  ~ find /lib/modules/$(uname -r) -type f -name rfcomm
➜  ~

loading it returns a 0 exit code

 ➜  ~ sudo modprobe rfcomm
➜  ~ echo $?
0 
➜  ~ echo 1 | doas tee /sys/devices/platform/thinkpad_acpi/bluetooth_enable
zsh: command not found: doas

I did give me a default controller after turning rfcomm on.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

Seems that after loading rfcomm the controller is recognized by bluetoothctl. Check if somehow it is blocked from loading.
* Following loading the module, does bluetooth still soft block? What happens when you try to unblock it?
* Replace doas with sudo and try to unblock it using the kernel interface again.

Other than that:
* After loading it, search for it in lsmod.
* In your find, search with double quotation marks arround the expression ("*rfcomm*")

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

What happens when unblock using kernel module?

echo 0 | sudo tee /sys/class/rfkill/rfkill0/soft

It is possible to completely disable rfkill so it can't block.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

still doesnt work and it seems modprob rfcomm was a fluke. Running that common doesn't seem to fix the no default controller available issue anymore.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

1. What do you mean by not working? Did it change the param value but still no controller listed? Please include the results of each proposed test.
2. Did you try to completely disable rfkill (by blacklisting, adding to kernel param: rfkill.default_state=1 and rebooting)? What is the output of:

bluetoothctl list

3. Please include full log following:

sudo journalctl -b | curl -F 'file=@-' 0x0.st
sudo dmesg | curl -F 'file=@-' 0x0.st

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

yeah after running that command the bluetoothctl can't find a default controller.

I added rfkill to the blocklist and added rfkill.default_state=1 to the kernel params but bluetooth still does not start on boot and no default controller is still found when running bluetoothctl.

bluetoothctl list does not return anything either

➜  ~ sudo journalctl -b | curl -F 'file=@-' 0x0.st

➜  ~ sudo dmesg | curl -F 'file=@-' 0x0.st

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

hci0 device is missing from dmesg so no BT controller.

* No microcode is loaded upon boot. Try loading it and see if hci0 device appear in dmesg (and in: btmgmt info).
* Please include: "lsub | grep -i bluetooth". Perhaps there's something specific with the BT device.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

what commands do i use exactly to follow your first bullet point? I also checked to see if intel-ucode is installed and it already is

also

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

* Simple search would show you the command is: lsusb.
* The microcode should be loaded during boot like this.
When it does, it will appear in the kernel command line. The provided dmesg is missing the microcode:

Command line: BOOT_IMAGE=/boot/vmlinuz-linux-lts root=/dev/mapper/volgroup-lv_root rw loglevel=3 quiet rfkill.default_state=1

Do you load it differently?

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

looking at my grub file it should load in

this is in my grub config

        
        echo    'Loading Linux linux-lts ...'
        linux   /boot/vmlinuz-linux-lts root=/dev/mapper/volgroup-lv_root rw  loglevel=3 quiet rfkill.default_state=1

some recent files i found, can not seem to enable either of them. I can also confirm this is not a hardware issue as I have windows dual booted on this laptop and bluetooth works on windows without an issue.

Re: [SOLVED] x1 carbon gen 7 cannot seem to get my bluetooth to work

Don't do that, your previous bump was fine because it added new information the last one is not: https://wiki.archlinux.org/title/Genera … es#Bumping

Check your UEFI menu whether something is blocked there, if you happen to have a dualboot and access to Lenovos Vanguard software make sure BT isn't disabled there/that flight mode is not activated in vanguard or similar, speaking of dualboot, double check and ensure fast boot is disabled, various BT Wifi issues are the first victim of that: https://wiki.archlinux.org/title/Dual_b … ibernation

As for these files, try writing the relevant token to them e.g. 

echo enable | sudo tee /proc/acpi/ibm/bluetooth
echo 1 | sudo tee /sys/devices/platform/thinkpad_acpi/bluetooth_enable

hey, I have already tested everything you mentioned. The files go back to their default values after running those commands listed, checked and UEFI is not blocking bluetooth. I will check the fast boot option though. I will say I have no issues with WiFi and as mentioned bluetooth works fine on the windows installation.

double checked UEFI settings, bluetooth is enabled and tried disabling fast boot but still having the same issues.

Bluetooth gets initlaized but when I do a systemctl status on bluetooth it is listed as inactive and I have to start the service manually with everyreboot even though the service is enabled.
