Hello,
My bluetooth seems to be running fine but the strange thing is that when i try to scan to connect to other bluetooth devices it seems like it is taking forever to scan and also it is not discoverable by other devices.
Can anyone help me on this?
Thank you in advance.
Here are some of the commands that I used when following the troubleshoot:

This is where i feel like there’s something wrong with my bluetooth and it’s cfg file. Correct me if i’m wrong and sorry i’m kinda new into linux. Thank You.

So I installed 5.4 LTS but when reboot the system, it doesn’t display any bootloader instead it boots directly(into 5.8). Does this mean that I have to install a bootloader or is there a different way to enable it?
thank you for your reply. Infact, i didn’t even search before replying it here so i found a post similar to your reply and I will reboot now and check if it works.
I downgraded to kernel 5.4 but still the same result
Here are few of the bluetooth commads that i tried with(even GUI):
bluetoothctl
Agent registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# discoverable on
Changing discoverable on succeeded
[CHG] Controller 18:4F:32:F9:91:5A Discoverable: yes
[bluetooth]# pairable on
Changing pairable on succeeded
[bluetooth]# scan on

Yeah: it’s a hardware failure or a kernel issue…
Do you have a dual boot system and if yes: does it work under the other OS?
If not: try the 5.9RC6 kernel (last ditch effort)
If that doesn’t solve the issue: replace the hardware…
if it really is a hardware failure, don’t forget to press the Solution button on the last response so that the next person that has the same problem as you will know what to do too!
Thank you for your suggestion but i tried live booting ubuntu but bluetooth seems to give the same problem (which is it keeps scanning forever). Just like @Fabby said it could be a hardware problem. For now I will just mark @Fabby’s answer as solution and will make sure to give an update on this post. Thank you @kagetora13 for your response
so i found a post similar to your reply and I will reboot now and check if it works.
