Bluetooth not working on laptop

Midline · February 10, 2022, 10:02pm

I bought a laptop on which the vendor (Slimbook) installed Elementary OS 6.1. They have a forum where we can ask questions but it is in Spanish. I don’t know Spanish.

My Bluetooth does not work for some reason. Even when I switch it on, the icon shows that it is switched off. I attempted to switch it on from the system settings also but that does not work either. It is unable to discover any bluetooth devices. I recently bought a bluetooth amplifier that my Mac picks up but my Slimbook does not.

If someone can help me troubleshoot this, I would appreciate it very much. The bluetooth icon always looks like in the image below even when turned on.

My laptop configuration is as below:

Perhaps @vasileios wouldn’t mind taking a look when time permits.

Thank you!

Hey @Midline!
Thank you for posting the output of Inxi! Though it doesn’t show your BlueTooth, which has me believe it hasn’t detected it at all. Can you send me a screenshot of the output of:

lspci

This will create a list of all the hardware components it picks up.

Also, just to be safe, can you also send me a screenshot of the following command:

lsusb

This will look for all USB related components.

Thank you!

Hi @vasileios
Thanks for responding. Sorry for the late response. Things got crazy busy at work.

Hey @Midline!
Thank you for posting the above info!
The first command only shows the generic version of the bluetooth device. The LSPCI gave the exact model, which happens to be an integrated WiFi and Bluetooth on the same chip (Intel Corporation Wi-Fi 6 AX200) which you can see here:

https://ark.intel.com/content/www/us/en/ark/products/189347/intel-wifi-6-ax200-gig.html

This specific chip had issues on older Kernels, like 5.4. However, you are running 5.11, so the firmware issue shouldn’t be affecting you. Just to be on the safe side, what does the following output give you?

journalctl -b | grep iwlwifi

From people who had a similar issue, the only thing that worked was to manually “reset” the device. For the record, I am not familiar if this is something you can do in the BIOS of your system. Perhaps a power cycle with the Bluetooth and WiFi disabled, followed by another power cycle with both of them enabled.

One guy removed the module and then reconnected it. After that, both Bluetooth and WiFi worked normally. However, I don’t know how this module is connected to your mainboard. If it is something you can detect (WiFi modules are usually attached and cable-connected to the mainboard), then you can disconnect it, power your system on, then power off and reconnect it.

However, before you do that, check the journalctl above. Hopefully, it’s a firmware issue.

Midline · February 17, 2022, 1:58pm

Hi @vasileios

My WiFi works so I’m hoping that this is a firmware issue. Unplugging stuff on the mainboard is not something I look forward to.

Is there a way for me to upload a text file? I have the long form output of hwinfo. This output contains a copious amount of information with several references to bluetooth.

Hey @Midline!
I just enabled the txt extension upload for the forums. As long as the files are not huge, they can be uploaded now.
As I see from the output of journalctl, the firmware loads and activates normally, which makes me think that this is a hardware reset issue. Before you go into the mainboard (trust me, I feel your pain, and I always end up with more screws available when I put everything back together!), how about you completely disable the module inside the BIOS and perform a full power cycle before re-enabling it?

Midline · February 17, 2022, 10:04pm

Thanks @vasileios

How do I disable the module inside the BIOS?

I have attached the long form output of hwinfo for your review.

hwinfo.txt (618.1 KB)

vasileios · February 17, 2022, 10:51pm

Hey @Midline!
I looked at the file you sent me and it appears that the firmware is indeed loaded:

<6>[ 5.477669] Bluetooth: hci0: Waiting for firmware download to complete
<6>[ 5.478659] Bluetooth: hci0: Firmware loaded in 1340895 usecs

<4>[ 5.666377] Bluetooth: hci0: MSFT filter_enable is already on

Per the BIOS, it should be located under “On Board WiFi” or “BlueTooth”. Both of them are under the same chip. If you can provide a screenshot or two of the respective tab on your BIOS, I believe we can spot them.

Midline · February 18, 2022, 10:03pm

@vasileios here are images of my BIOS screens.

vasileios · February 19, 2022, 6:31am

Hey @Midline!
It would appear that your laptop does not have such option to disable the WiFi.

If you look at a guy who had the exact same issue:
https://forums.linuxmint.com/viewtopic.php?t=340234
At the last post, he found out that he had to basically disconnect and reconnect his module.

However, out of curiosity, before you attempt anything on the hardware, let’s see if a bigger kernel may help. Open up a terminal and execute:

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

Then run Mainline and select the latest kernel. Once it installs, reboot and - if the menu appears - boot into the latest (should be the 5.15 currently). Check to see if that helps.

Another option would be to install the Graphic User Interface for Blueman (Bluetooth Manager) and see if that can help you our of the pickle.

sudo apt install blueman

Once it installs, open it up (as Blueman Bluetooth Manager) and alternate its options as I have in the screenshot:

Check between NetworkManager and Blueman.

I hope… something above helps!

Midline · February 25, 2022, 6:33pm

Thanks @vasileios

I will try this over the weekend. I’m also experiencing another issue wherein my keyboard and mouse get deactivated after a suspend. I’ve tried everything recommended on various Linux forums but nothing has worked so far. Perhaps a kernel update might help. I will also try and install Zorin on an external NVMe drive and see if that solves these issues.

Very sorry for the late response. Was down with the flu and then had tons of stuff to catch up to when I got back to work mid-week.

vasileios · February 26, 2022, 8:46pm

Hey @Midline!
I wish you great health and to feel better, soon!
Also, don’t worry about delayed responses. My schedule has been so hectic of late, that I completely understand.

The truth is, that some laptops do have this issue with the suspend function. It’s a power distribution issue, which may be connected to the switching on of the graphics card/chip. The delay that takes place there bypasses the timeout of the keyboard re-activation, which renders that input source inoperable. We hope this will be resolved as the kernels get updated. Speaking of which, the new LTS versions are coming up in a month and a half (with Kernel 5.15), so… we’re getting there!
