Bluetooth troubles

tealtydes · January 28, 2024, 4:11pm

Hardware wise I’m using an intel 13700k. Running tmpfs root & home with zfs mounted to /keep

I’ve read all of the troubleshooting information I can find & seem to be having no luck.
Every now & then on reboot I will not see No Default Controller when running any commands with bluetoothctl but this is a rarity.

Here is what I have so far. I have little understanding of bluetooth settings as I’ve always had a dongle of some sort & have just been throwing snippets at the problem to no avail in all honesty. Any advice would be great if anyone has bumped into a similar issue.

    #environment.systemPackages = with pkgs; [bluez5-experimental bluez-tools];
    services.blueman.enable = true;
    environment.systemPackages = with pkgs; [bluez bluez-tools];
    hardware.bluetooth = {
      enable = true;
      powerOnBoot = true;
      #package = pkgs.bluez5-experimental;
      package = pkgs.bluez;
      settings.Policy.AutoEnable = "true";
      settings.General = {
          Enable = "Source,Sink,Media,Socket";
          Name = "Hello";
          ControllerMode = "dual";
          FastConnectable = "true";
          Experimental = "true";
          KernelExperimental = "true";
      };
    };
    systemd.services."bluetooth".serviceConfig = {
      StateDirectory="";
      ReadWritePaths="/keep/var/lib/bluetooth/";
      ConfigurationDirectoryMode = "0755";
    };
    fileSystems."/var/lib/bluetooth" = {
      device = "/keep/var/lib/bluetooth";
      options = [ "bind" "noauto" "x-systemd.automount" ];
      noCheck = true;
    };
    systemd.tmpfiles.rules = [
      "d /var/lib/bluetooth 700 root root - -"
  ];

What does dmesg say if you rmmod/modprobe (reload) bluetooth module?

tealtydes · January 28, 2024, 4:17pm

I have since restarted the bluetooth service but on boot I see that the service is dead / inactive.

~> dmesg | grep -i bluetooth                                                         01/28/24 16:16:49 PM

I am seeing these errors when checking the status though.

Every now & then on reboot I will not see No Default Controller when running any commands with bluetoothctl but this is a rarity.

So basically your problem is that your bluetooth controller doesn’t come up at boot?

In that case, what does bluetoothctl show give you?

Also which hardware is your bluetooth controller? Are you using a dongle still or something built in your wifi card? Or whatever else?

tealtydes · January 28, 2024, 4:40pm

Yes I don’t think it’s being recognized at boot. I have an Intel Wi-Fi 6E AX200 & I’m wired in at the moment as bluetoothctl is not finding anything.

/keep/etc/nixos> bluetoothctl                                                        01/28/24 16:34:34 PM
Agent registered
[bluetooth]# show
No default controller available

after running journalctl -xe | grep bluetooth I am seeing

Jan 28 16:27:49 itx bluetoothd[65295]: src/main.c:check_options() Unknown key Enable for group General in /etc/bluetooth/main.conf

this remains the case after removing the Enable = "Source … from the config.

APCodes · January 28, 2024, 4:57pm

So it’s an Intel one, these are typically quite decent. Do you have wifi available when you don’t have bluetooth? Is the iwlwifi module loaded?

Judging from looking at Arch Linux forums, you might not be the only one having experienced something like this.

tealtydes · January 28, 2024, 5:25pm

Yep wifi’s working fine.

~> lsmod | grep iwlwifi                                                                                                                                     1 01/28/24 17:22:37 PM

I’ll try updating bios & firmware & see if that helps out any.
I’ll maybe try switching to the zen kernel if that doesn’t help things
& then come back with more info at that stage either way I guess.

tealtydes · January 28, 2024, 6:40pm

Updating the bios doesn’t seem to have helped though I have spotted this.

I have to say: I hate bluetooth configuration

A question aside… why do you need all this configuration?

      settings.Policy.AutoEnable = "true";
      settings.General = {
          Enable = "Source,Sink,Media,Socket";
          Name = "Hello";
          ControllerMode = "dual";
          FastConnectable = "true";
          Experimental = "true";
          KernelExperimental = "true";
      };

I am also wondering if there might be some issue with your general setup. This one: “Running tmpfs root & home with zfs mounted to /keep”.

In order to exclude that: Did you try running another Linux distro and attempt using your bluetooth controller?

tealtydes · February 24, 2024, 9:40pm

I threw together a bunch of hacks in desperation.

I’m pretty sure this was the ticket.
xdg.autostart.enable = true;

Current set-up for reference

{pkgs, ...}:{os=
{
   hardware.bluetooth = {
      enable = true;
      powerOnBoot = true;
      package = pkgs.bluez5-experimental;
      settings.Policy.AutoEnable = "true";
      settings.General.Enable = "Source,Sink,Media,Socket";
   };
   services.blueman.enable = true;
   environment.systemPackages = with pkgs; [
        bluez5-experimental 
        bluez-tools
        bluez-alsa
        bluetuith # can transfer files via OBEX
      ];
};}

Punchy_Cucakes · March 14, 2024, 5:51pm

If you managed to get bluetooth working, can you post your whole configuration.nix? I’m running into a similar issue where wifi is working fine (always has – pretty painless), but no combination of fixes and tricks that I’ve found elsewhere seems to do the trick for bluetooth. I’m not sure whether it’s my configuration.nix, or maybe some other hardware/firmware issue that I don’t know how to diagnose.

As an aside, do you know whether a full reboot is required to get these changes working, or if nixos-rebuild switch is enough?

rjpc · March 14, 2024, 7:40pm

what issue are you seeing? Seems like the original issue was they weren’t even seeing their bluetooth controller. For the record I use bluetooth on NixOS and it works well. What does hciconfig --all produce?

Punchy_Cucakes · March 14, 2024, 8:10pm

Yep, that’s the same issue I was having. bluetoothctl show responds “No default controller available”

When I run hciconfig --all it doesn’t print anything.

rjpc · March 14, 2024, 9:11pm

is it onboard the motherboard (check the BIOs for an option to enable the controller) is it a dongle? Perhaps you don’t have the right driver? What chipset does it use? what does dmesg say? what about the system journal?

kranium · March 15, 2024, 2:04am

I had a similar error when trying to “free” my laptop from proprietary blobs.

See if using hardware.enableAllFirmware = true; with a reboot makes a difference.

Punchy_Cucakes · March 15, 2024, 4:38pm

Using hardware.enableAllFirmware = true; plus a reboot did the trick!

I’m going to try to answer the questions rjpcasked just in case it helps someone else in the future maybe.
Not a dongle, builtin. The firmware I have that worked is intel/ibt-17-16-1.sfi which I just pulled from the dmesg output. Not sure how to get the rest tbh.

Thanks y’all!

rjpc · March 16, 2024, 4:59am

Great! Glad to hear it was simple. I’ve had hardware.enableRedistributableFirmware = true; set for years too but I’m sure that’s covered by AllFirmware

DockterTeagle · September 7, 2024, 6:54pm

I’m currently having a similar issue, that is it is related to Bluetooth. i am trying to connect an Xbox Elite Wireless controller 2, and it shows up in dmesg but it is giving no input:
here is the relevant parts of dmesg:

  183.871107] input: Microsoft X-Box One Elite 2 pad as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/input/input42

furthermore though it shows up in dmesg it doesn’t show up in bluetoothctl list, the output of which is only one line, which is (I think) the bluetooth adapter
