Bluetooth keeps connecting and disconnecting

Ask Fedora
1

Hi you all,
I’m facing some issues with the bluetooth from about two weeks.
Basically the Bluetooth keep disconnecting randomly for about 2 seconds and after all is restored, but this problem is very annoying, and I really don’t know how to fix it.

I’m not a super good linux user, so I need help also to dig into the problem issue.

This is my PC infos:
Operating System: Fedora Linux 43
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.10.3
Kernel Version: 7.1.13-100.fc43.x86_64 (64-bit)
Graphics Platform: X11
Processors: 16 × Intel® Core™ 7 240H
Memory: 32 GiB of RAM (30.8 GiB usable)
Graphics Processor: Intel® Graphics
Manufacturer: LENOVO
Product Name: 21TFCTO1WW
System Version: ThinkPad E16 Gen 3

[EDIT]:
I have Windows 11 in dual-boot, I use Windows rarely but this could be relevant.

If you need other information please tell me.

Many thanks to who wants to help me.
Alan

Welcome to fedora @alanmasu

Can you give more information:

Mostly Bluetooth works over the network adapter. If there is a problem interrupts can happen.
