Intel AX200 Bluetooth - Failed to send firmware signature

[MrGlasspoole]

I can't make Bluetooth working.

Maybe it's because of "Failed to send firmware signature"

WLAN is working. But i find it hard to figure out what firmware is needed.
This site does says nothing about Bluetooth:
https://www.intel.com/content/www/us/en ... rking.html

With a lot of Googlefu it seems like

Code: Select all

iwlwifi-cc-a0-46.ucode
ibt-20-1-3.sfi
ibt-20-1-3.ddc

are the right ones?
But i ask myself how do you know that?

This site has nothing about AX200:
https://packages.debian.org/bullseye/al ... re-iwlwifi

Since that AX200 has a cable to USB, shouldn't i see something Bluetooth here:

Do i need all that "failed with error -2" stuff?
Because for testing i did install "firmware-iwlwifi" and the outcome is the same.

[stevepusser]

Did you install the newer firmware from backports?

If that's a no-go, you could try this port of the Ubuntu firmware package: https://build.opensuse.org/package/show ... x-firmware

or try the MX Linux 19.2 AHS edition, which has that firmware preinstalled, from a Live USB or DVD, to see if it's working there first.

[MrGlasspoole]

That firmware-iwlwifi is from backports

I changed sources.list from:

But seems like there is nothing new about firmware:

EDIT
OK that linux-firmware from openSUSE is a package for everything - right?
Then i wonder why all tutorials are talking about single files where its hard to find out what is what

So i did remove that non-free from my sources.list. and:

Code: Select all

$ sudo apt clean
$ sudo apt update
$ sudo apt full-upgrade

$ echo 'deb http://download.opensuse.org/repositories/home:/stevenpusser:/new-hardware-support-buster/Debian_10/ /' | sudo tee /etc/apt/sources.list.d/home:stevenpusser:new-hardware-support-buster.list
$ curl -fsSL https://download.opensuse.org/repositories/home:stevenpusser:new-hardware-support-buster/Debian_10/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home:stevenpusser:new-hardware-support-buster.gpg > /dev/null
$ sudo apt update
$ sudo apt install linux-firmware

Now i have:

Code: Select all

$ hcitool dev
Devices:
        hci0    14:F6:D8:6B:10:EC

$ sudo rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

If i do "devices" in bluetoothctl should i see something? Or does it only list connected devices? Because nothing shows up if i do that.

Code: Select all

$ bluetoothctl
[bluetooth]# agent on
Agent is already registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# scan on
Discovery started
[CHG] Controller 14:F6:D8:6B:10:EC Discovering: yes
[bluetooth]# devices
[bluetooth]#

So would normally that be enough?

Code: Select all

iwlwifi-cc-a0-46.ucode
ibt-20-1-3.sfi
ibt-20-1-3.ddc

Or does it need everything? because there is still some "failed with error -2":

Code: Select all

Yeah, Debian firmware hasn't been updated for a year now, so it's falling behind. That forced me to port over the linux-firmware package for the AHS (Advanced Hardware Support) version of MX Linux...we couldn't ship it and then expect users to manually get and install the firmware from the kernel git tree, could we?

If you want to manually install it from git, that's your other option. That's appeared in many other recent threads here--just search for firmware.

Just edited my last posting and there are questions left
