Bug Description
SRU Justification:
[Impact]
Bluetooth for Intel Wireless-AC 9560 variant 9df0:0034 still fails to
pair BT LE HID devices on recent (>= 4.19) kernel.
[Fix]
Bluetooth firmware REL0450 or newer is required to fix this issue.
[Test Case]
Install new firmware blob to /lib/firmware/
completely and wait for a couple minutes to trigger firmware reloading
at the next boot. Then perform Bluetooth LE HID devices pairing to
verify if the proposed fw fixes this issue.
[Regression Risk]
Low. This affects only sub models of Intel JeffersonPeak Bluetooth chip
series using these firmware blobs.
========== Original Bug Description ==========
This is similar to https:/
I have an ASUS ZenBook 14 - UX433FA - which based on this - https:/
With kernels older than 4.20 I can successfully pair my bluetooth mouse (Logitech MX Master) - but with newer kernels I get "Bluetooth: hci0: request failed to create LE connection: status 0x0c" messages.
I'm running Linux Mint 19.1
I tried installing linux-firmware 1.173.8, and it didn't seem to help - I also downloaded 1.173.9 proposed from here: https:/
Both after a cold reboot and a warm reboot I see
[ 14.724438] Bluetooth: hci0: Firmware revision 0.1 build 201 week 49 2017
in my dmesg output.
Bluetooth works just fine with earlier kernels (however other aspects of the laptop like suspend don't work as well, which is why I'm trying the newer kernel.

Thanks @vicamo - I followed the process you described and attached the output.

Hi @wjbaird, thank you for the logs. From your lspci output, we should be able to confirm it's a "Intel(R) Dual Band Wireless AC 9560"[1], and we should have the support in linux-oem-osp1 kernel since bug 1833065. For -generic kernel flavors, the backport-
For bluetooth, unfortunately we still have no luck to retrieve the firmware name from dmesg. I met this before. All I know is that it takes a complete power off, wait for a period, power on and you may find the line that gives firmware name in this first boot. With the blob firmware name, we may begin to find out which revision of that given blob works for you. If the latest one from linux-firmware git repository[3] still doesn't work well, then we'll probably need to file a bug to Intel instead.

Thanks @vicamo. I powered off and let it sit for about 45s before the log I sent you... I'll try again and leave it off for a longer period and see if I see the line...
| Warren Baird (wjbaird) wrote : | #7 |
I tried it for about 3 minutes this time, and I think I see the line you are looking for:

I'll attache the entire log...
| Warren Baird (wjbaird) wrote : | #8 |
| Warren Baird (wjbaird) wrote : | #9 |
Oh - and now it looks like bluetooth is working! Is it possible that turning it off for 45s just wasn't enough? I thought that should be plenty...?
| You-Sheng Yang (vicamo) wrote : | #10 |
Ha, thank you. That's what I'm looking for.
So now we have the firmware name, and the next step would be to find out which version will work for you. And so far we have:
* Bionic: REL0440
* Cosmic: REL0329
* Disco: REL0420
* korg/master: REL0472
Since you mentioned neither linux-firmware version 1.173.8 nor 1.173.9 would work for you, which was last updated to REL0440 at bug 1829737 for the same symptom on also 9560/9462 devices, maybe that's one 9560 variant that we don't have. Then I would like ask you for a favor, to confirm which version(s) works for you:
and/or,
And please also give me the md5sum of /lib/firmware/
From your comment #9 I suppose at least REL0472 should work, but I also need to know if REL0450 is sufficient enough. Thank you.
| Warren Baird (wjbaird) wrote : | #11 |
The md5sum of what is current installed and working is:
5740378bfc04810
Which is the same md5sum as the rel0472 version you link to above, so yes, that does seem to be working.
I've downloaded the rel0450 version now, I'll install it, and leave my computer off for at least 5 minutes this time, and see what happens...
| Warren Baird (wjbaird) wrote : | #12 |
OK - after installing the rel0450 version, shutting down for 5 minutes and rebooting, Bluetooth is still working for me. Here's the new md5sum
b24eceb411cf636
I'll upload the latest output of dmesg | egrep -i "blue|firm", in case that helps.
is there a downside to leaving the firmware content that I got off the git site in my /lib/firmware folder for now, or should I reset it?
Thanks for your help!!!
| Warren Baird (wjbaird) wrote : | #13 |
| You-Sheng Yang (vicamo) wrote : | #14 |
Thank you, Warren. So I think I can begin to send a patch to the series don't have REL0450 ibt-17-16-1.sfi, so that owners of the same devices don't have to manually download again.
For polluted /lib/firmware, I think I would restore what it was and copy only ibt-17-16-1.sfi to keep Bluetooth working. Because I myself run apt updates everyday, and I don't want to break any installation script as possible. Besides, yes, keep things simple would also be nice.

Hi, @wjbarid,
In order to determine the right hardware spec on your device, please attach `sudo lspci -vvnnk` output. It will contains subsystem ID that can be used to find the right iwlwifi model.
For bluetooth firmware blob name, you should try:
1. clone https:/
$ sudo mv /lib/firmware/intel /lib/firmware/
$ sudo cp -a _git_cloned_
2. power off your machine completely and turn it on again *after* 30 seconds or so.
3. capture the dmesg output for Bluetooth|hci:
$ dmesg | egrep -i 'blue|hci'
You should find something like:
Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
