Bluetooth not turning on

This is my first post here so apologies for any errors.


I encountered an issue where I could not turn on my Bluetooth in spite of toggling it to the on position in Settings (see image below).


rfkill list all initially showed Bluetooth being Soft Blocked but unblocking that did not resolve the issue.

The output of inxi -Fxz returns

Note the distro being Nobara 36, which is a, “modified version of Fedora Linux”. I have seen this same issue posted to various forums from people using Fedora so believe it is relevant to post it here.


Missing file(s) in the /lib/firmware/intel directory.


For me, the solution came first by inputting dmesg | grep -i bluetooth into ternminal:

Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-19-0-4.sfi (-2)

(I found a Debian bug report that summarised the solution to the issue in 2020:

I downloaded the ibt-19-0-4.sfi and ibt-19-0-4.ddc files (download the ones relevant to your error) from

Next I copied those files from my downloads folder to /lib/firmware/intel with:

sudo cp /home/[name]/Downloads/[file] /lib/firmware/intel
  • [file] in my case is ibt-19-0-4.sfi and ibt-19-0-4.ddc

To verify they copied over I ran ls /lib/firmware/intel

$ ls /lib/firmware/intel
ibt-19-0-4.ddc  ibt-19-0-4.sfi  sof  sof-tplg

After rebooting it works as expected, I used bluetoothctl to manage my bluetooth connections.


Thank you for sharing this workaround. Please file a bug report on it so the issue may be fixed in the future.

Well, it might not be a problem in Fedora, just in Nobara. In my Fedora 37, I have lots of /usr/lib/firmware/intel/ibt* files present.

@butlerwil You can boot a Fedora 37 Workstation Live image and test if you can reproduce the bug or not. If you can, please file a bug into , if you can’t, then it’s a Nobara-specific problem.

A bug report has been filed and resolved. The missing firmware packages are shipped with fedora and compressed.

If anybody encounters this issue sudo dnf install linux-firmware should solve the issue.


Please always provide links to bug reports.
