Need assistance with Bluetooth problems

Pre-Release Discussion
1

My Bluetooth works but stops working after restart. My laptop is newer Asus ProArt P16. The background is that this issue has been addressed with the latest kernels. Which I am using with Ubuntu 25.04 kernel 6.14. So the Bluetooth has been working when there are updates but after any bluetooth updates it stops after a restart. Then I can’t turn it it back on. It may be related to the following issue. These laptops are very similar. https://bbs.archlinux.org/viewtopic.php?id=298853

Please let me know if anyone can help. Thank You

I am wondering if it is related to the above issue of the link I provided on the Arch forum. About starting after networking.

I am going to hazard a guess - Mediatek device?

I do find that for wireless

Foxconn device - I wasn’t expecting that, but nevermind
Although same device driver btusb

I have experienced similar problems i.e. Bluetooth fails after restart, but mine is a slightly different device
Here’s mine (mediatek 7921 wifi and bluetooth combined)

Now, I don’t know how to fix the problem but I do know that, for my device, Ubuntu 24.04 with kernel 6.8.0-52 works flawlessly - both first boot and restart.

Often, when using a 6.11 kernel, I have had to resort to this trick to re-activate Bluetooth:-

  • Close applications and power off
  • Remove the power cable (desktop) (laptop - remove battery?)
  • Press and hold the power button for more than 30 seconds
  • Re-attach power cable (or battery)
  • Boot the PC

Here’s a couple of links where I have tried to investigate and fix a similar difficulty.
So far, unsuccessfully

I’ll keep an eye on this thread to see what transpires.

Moving to pre-release. We provide no official support for pre-release versions.
