Intel Bluetooth stopped working on Fedora 41 on my Thinkpad X1 Carbon Gen13 – No Default Controller Available

00:14.3 Network controller [0280]: Intel Corporation BE201 320MHz [8086:a840] (rev 10)

(No output)

Issue Description

• bluetoothctl shows: “No default controller available”
• hciconfig hci0 up fails: “Can’t init device hci0: No such file or directory”
• Bluetooth service is running (systemctl status bluetooth), but the hardware is not detected properly
• rfkill list shows that Bluetooth is not soft- or hard-blocked
• Kernel module bluetooth is loaded (lsmod | grep bluetooth)
• Intel firmware fails to load (dmesg output below)
• Firmware package was reinstalled, but the issue persists

Checking Bluetooth Service

systemctl status bluetooth

Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: enabled)

Checking for Bluetooth Devices

Checking Kernel Modules
lsmod | grep bluetooth

Checking Available Firmware
ls -lah /lib/firmware/intel/ | grep ibt
-rw-r–r–. 1 root root 53K Mar 17 20:03 ibt-0190-0291-iml.sfi
-rw-r–r–. 1 root root 847K Mar 17 20:03 ibt-0190-0291.sfi
-rw-r–r–. 1 root root 703K Mar 17 19:57 ibt-0190-0291-pci.sfi.bak

It seems ibt-0190-0291-pci.sfi is missing or outdated.

What I Tried

1. Reinstalling firmware
   sudo dnf reinstall linux-firmware

→ No effect

2. Restarting Bluetooth service
   sudo systemctl restart bluetooth

3.Unloading and reloading modules
sudo modprobe -r btintel_pcie btintel bluetooth
sudo modprobe btintel_pcie

→ Fails: “Module bluetooth is in use”

Checking running processes using Bluetooth
sudo lsof | grep bluetooth

→ Various processes (wireplumber, gnome-shell) are using libbluetooth

Checking Kernel Boot Logs
journalctl -xe | grep -i bluetooth

Bluetooth: hci0: command 0xfc05 tx timeout
Bluetooth: hci0: Reading Intel version command failed (-110)
Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-0190-0291-pci.sfi (-2)
Bluetooth: hci0: MSFT extension not registered

Additional Information

• I tried downgrading the kernel (dnf list --showduplicates kernel), but 6.10 is unavailable.
• The issue persists on multiple kernels (6.13.6, 6.13.7, 6.11.4).
• Bluetooth was working fine before.

Questions

• How can I manually update/download the missing firmware (ibt-0190-0291-pci.sfi)?
• Could this be a Fedora 41 bug or a regression in the latest Intel firmware?
• Is there a way to force a downgrade to an older firmware version?

Any help would be greatly appreciated!

Running journalctl --no-hostname --follow in a terminal window and then sudo dnf reinstall linux-firmware in another window may help understand why you don’t have the current firmware.

Edit: frimware → firmware

I have a very similar issue, my Bluetooth worked in the past (up until about 3/4 days ago) but was sometimes a bit spotty (requiring a restart or two to work). Now it doesn’t work at all. KDE reports “no adapters available”, but lsusb clearly reports the bluetooth adapter as available.

I have the same issue.

Found a person on reddit confirming that going back to an older version of linux-firmware works. But I can’t quite figure out how they did it: Link

[ergocogito (John Kiwami)]

I manged to successfully downgrade to linux-firmware-20241017-2.fc41 from linux-firmware-20250311-1.fc41 using dnf downgrade linux-firmware.

Unfortunately this doesn’t seem to have solved the problem, symptoms are the same and dmesg still reports

[    4.106979] Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-0190-0041-iml.sfi (-2)
[    4.107500] Bluetooth: hci0: Failed to read MSFT supported features (-56)

Very strange, I don’t know enough about any of this to draw any conclusions though.

Found a maybe-relevant bugzilla report: 2352736 – Bluetooth: hc10: command 0xfc05 tx timeout

I also have the same issue with HP Omnibook Flip. I tried the steps provided on the last comment here, but still no luck: FEDORA-2025-7f56eb37a0 — security update for linux-firmware — Fedora Updates System

Also copied the firmware manually to /lib/firmware/intel/ , but got the same result.

Apparently, it will be fixed on a newer version of linux-firmware, which if it goes as the previous versions, should be release around the 2nd week of April.

Same issue on an Asus Zenbook S14 but the fix mentioned here worked for me (also posted by @angourakis above).
