If you shutdown Windows (not reboot or hibernate) then cold boot to Ubuntu, do you see the Bluetooth device OK?

no Bluetooth does not see ubuntu and it bluetooth does not work in ubuntu.

What is the output of:

sudo rfkill list

0: acer-wireless: Wireless LAN
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

OK and the output of:

bluetoothctl

Waiting to connect to bluetoothd...

and nothing happens anymore

https://youtu.be/1j0KlU4JPOM

Does that help. There are commands at the 1:50 mark.

sudo apt-get install linux-firmware

0 packages updated, 0 new packages installed, 0 packages marked for removal, and 0 packages not updated.

after commands

sudo modprobe -r btusb
sudo modprobe -r ath3k
sudo modprobe ath3k
sudo modprobe btusb

nothing happened

bluetoothctl writes the same

in the settings in the bluetooth item it says - no bluetooth adapters found

You may want to make sure you have the latest BIOS

I have the latest BIOS installed and just to clarify and remind you... in Windows 7 everything works fine, so the problem is clearly in Ubuntu

I would try this:

Terminal: sudo rfkill unblock Bluetooth
systemctl restart bluetooth
If nothing else works try restarting the computer.

sudo rfkill unblock Bluetooth
rfkill: invalid identifier: Bluetooth

systemctl restart bluetooth
asked for a password and that's it

Now I'll try to reboot

the situation has not changed at all! no bluetooth adapter found

I ran out of ideas.

the situation has not changed at all! no bluetooth adapter found

As far s I know Qualcomm Atheros AR9485 Wireless Network Adapter is only a WLAN adapter nd does not have bluetooth functions.
If you boot Windows and look it the device manager, is there a Bluetooth device listed, and if yes, what is its make and model?

Additionally, what output do you get for the command (in Ubuntu)

sudo dmesg | grep -i blue;

sudo dmesg | grep -i blue;
produces nothing.

Google tells me that Qualcomm Atheros AR9485 has bluetooth version 4.0. To answer your question with pictures proving this, I need a usb life with windows 7, now I don't have it. But if you don't believe me then write and I'll do it

Please forgive me! indeed there is no bluetooth on Qualcomm Atheros AR9485. I put it on a windows 7 laptop and found this. Looks like I forgot to change them.

But the problem remained unfortunately, now on a laptop with ubuntu there is a Ralink RT3290, there is 100% bluetooth and for reasons unknown to me it does not work in ubuntu.

and after installing RT3290, another problem appeared. the laptop has special keys for Wi-Fi and Bluetooth, they have a light indication of the operation of the modules. When the AR9485 was standing, only the Wi-Fi indicator worked, on ubuntu it just lights up, and when using windows it pulsates depending on the load. Now when the RT3290 is standing, the indication does not work at all.

I want to apologize again! please forgive Manfred Hampl and actionparsnip! the fact is that I have two laptops and four communication modules, two new and two old. And I have been observing the problem with non-working bluetooth on ubuntu for a very long time. two or three years, just now I just decided to take it seriously. here is confused. Sorry.

For the RT3290 Bluetooth you will need rtbth-dkms from blaze PPA as it was never included in the kernel
In terminal

sudo add-apt-repository ppa:blaze/rtbth-dkms
sudo apt update
sudo apt install rtbth-dkms

Then you can reboot, if Bluetooth doesn't work, check in terminal

mokutil --sb

If that show Secure Boot enabled, then it will have to be disabled in BIOS

If it still fails, in terminal

sudo modprobe rtbth

Only some of the AR9485 wifi cards had BT and they will have 2 MAC addresses on the card, the model number of my card that had BT was also labelled AR5B225

I'm sorry, I don't know how to start the assembly, I hope I did it right. I’m completely zero in Linux, it’s just that the laptop only pulls Linux due to a motherboard glitch

You may have to contact the maintainer of the PPA. What I did worked in Ubuntu 22.04 using the 5.15 kernel

To be honest, after today's marathon, I'm already starting to doubt Ubuntu very much. One does not work, then another. Trying to fix so a bunch of errors climbs. On windows xp, the laptop had to be put in a cold place to install windows, and so it turned off due to overheating. But then you can use it normally. On windows 7, the installation goes fine, but when watching online video for more than 2-3 hours, it turns off due to overheating. And after the experience acquired today, I think I can try windows 11 or 10 on it. There, the drivers are installed normally and the indication works properly, and there are no such problems with eternal errors and a lack of understanding why it does not work. Sorry, boiled up.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.
