Upon further investigation journalctl returns the following

For reference this is how i am setting it up in my configuration.nix

  hardware.enableAllFirmware = true;
  hardware.bluetooth = {
    enable = true;
    powerOnBoot = true;
    package = pkgs.bluez.overrideAttrs (finalAttrs: previousAttrs: rec {
      version = "5.78";

      src = pkgs.fetchurl {
        url = "mirror://kernel/linux/bluetooth/bluez-${version}.tar.xz";
        sha256 = "sha256-gw/tGRXF03W43g9eb0X83qDcxf9f+z0x227Q8A1zxeM=";
      };
      
      patches = [];

      buildInputs = previousAttrs.buildInputs ++ [
        pkgs.python3Packages.pygments
      ];
    });
  };

  services.blueman.enable = true;
systemd.services.bluetooth.serviceConfig.ConfigurationDirectoryMode = "755";
  services.dbus.enable = true;

  hardware.pulseaudio.enable = false;
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    audio.enable = true;
  };

i checked lsmod and dmesg and the device seems to be recognized. but bluetoothctl is not seeing it

curious why you have to set this but that seems to be what the error is complaining about?

Hi! Have you since figured this out? I’m also facing the same issue.

Also facing the same issue here, had this issue with 24.05, upgraded yesterday to 24.11, still the same issue. I stopped using NixOS as my daily OS because of this, not having bluetooth means no headset and no voice in meetings.

{pkgs, ...}: {
  hardware.enableAllFirmware = true;
  hardware.firmware = [pkgs.linux-firmware];
  hardware.bluetooth = {
    enable = true;
    disabledPlugins = [
      "ccp"
    ];
    powerOnBoot = true;
    package = pkgs.bluez5-experimental;
    settings = {
      Policy.AutoEnable = "true";
      General = {
        # Enable = "Source,Sink,Media,Socket"; # Does not work with bluez5 (Unknown key Enable for group Genera.)
        Experimental = true;
      };
    };
  };
  systemd.services.bluetooth.serviceConfig.ConfigurationDirectoryMode = "755";
  services.blueman.enable = true;
}

journalctl -a | grep bluetooth

I installed Ubuntu on a partition and bluetooth does work with my Sony headset under Ubuntu.

If your dmesg output includes something like this:

[   37.404405] Bluetooth: hci0: command 0xfc05 tx timeout

You might be able to get Bluetooth working by reloading the module:

hciconfig hci0 down
rmmod btusb
modprobe btusb
hciconfig hci0 up

This is obviously an unsatisfying solution and if I get a better one I’ll post it.

any update on this?
i am facing a similar issue
