Bluetooth not showing any device

Hardware Support
1

Specifically I'd like to connect my Apple Airpods 2nd gen to my laptop. But in the Bluetooth menu, despite being on, shows no devices (unlike my phone which shows plenty).

Please advice me on what to do, thanks.

Here's my specs:
18 Core
Lenovo IdeaPad 3 15IAU7
Intel Core i7
x86_64 CPU

Bluetooth itself is working, yes? Can You connect other Devices?

No, nothing shows as being detected. It did, however, work 3 days ago; it spontaneously stopped working for seemingly no reason.

Did you received any Updates? Maybe a Kernel Update? If yes, You can try it with switching back to an older Kernel. To do that, choose on the GRUB Menu on Startup the Option ''Advanced Options'' and there take the one with the older Kernel.

Hey Ponce, looks like were dealing with another situation, where will likely have to recommend the OP switch to, Kernel 6.14 in the GRUB advanced options ha? This new kernel 6.17 doesn't appear to be very stable, as I've seen at least 6 posts now, if not more, where problems related to 6.17.

Yeah, does seem to have some Issues with this Kernel. Hopefully future Patches will solve Stuff and don't make it more worse.

Hi, using Brave A.I. via Mojeek with Ubuntu 24.04 in search criteria as Zorin 18 is a fork of same gives:

" To connect Apple AirPods to Ubuntu 24.04, modify the Bluetooth controller mode by editing /etc/bluetooth/main.conf and changing ControllerMode to bredr or dual , then restart the Bluetooth service .

Step-by-Step Connection Guide:

  1. Edit Configuration : Open the terminal and run sudo nano /etc/bluetooth/main.conf . Locate the line #ControllerMode = dual and change it to ControllerMode = bredr (or keep it as dual if bredr fails). Save and exit (Ctrl+X, Y, Enter).
  2. Restart Service : Apply changes by running sudo /etc/init.d/bluetooth restart or sudo systemctl restart bluetooth .
  3. Pair AirPods : Place both AirPods inside the case, keep the lid open, and hold the button on the back until the status light flashes white.
  4. Connect : Enable Bluetooth in Settings and select your AirPods from the list. If the GUI fails, use bluetoothctl to scan, pair, trust, and connect the device manually.

Important Considerations:

  • Codec Compatibility : Ubuntu often defaults to the SBC codec; for better quality, ensure pipewire and libspa-0.2-bluetooth are installed via sudo apt install pipewire pipewire-audio-client-libraries libspa-0.2-bluetooth .
  • Microphone Limitations : Switching to bredr mode may allow pairing but can sometimes disable the microphone or prevent High Fidelity (A2DP) audio from working simultaneously with input.
  • Reverting Settings : Users report that after successfully pairing with bredr , they can often revert ControllerMode back to dual to restore full functionality for other Bluetooth devices.

Thanks for everyone's advice. I tried everything but no beuno - no devices show up at all no matter what.

Interestingly, when I boot into Windows (AtlasOS), the device showed up briefly then disappeared, none showing up afterwards. Could this be a hardware issue? This is a brand new laptop that has had its bluetooth work just 3 days ago.

Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE

It's Wayland
