Linux 5.15.74-051574-generic bluetooth not showing devices

Asked by Anurag Dhiman

I have installed the ubunut version 22.04 but my bluetooth is not showing the devices. I tried to fix it with the help of askUbuntu but not found any solution. Please guide me through the solution. I will be appreciate this. I am pasting a link below if you want to see the output of: sudo dmesg | grep -i blue

OK,

what is the output of:

apt-cache policy linux-image-unsigned-5.15.74-051574-generic

You can clear up the cruft on the system with:

sudo dpkg -P `dpkg -l | grep linux-image-5.15 | grep ^rc | awk {'print $2'}`

One of the possible causes for your problem is, that you do not have the standard kernel packages installed, but a foreign version. Is there a specific reason that you have installed that kernel version?
Have you tried the standard kernel for Ubuntu jammy (Jammy comes with 5.15.0-52-generic)?

Your output does not tell make and model of your bluetooth device, probably some kind of rtl8852.
To identify it, what is the output of the commands

lsusb
lspci

This above repository didn't work.
This one did: git clone https://github.com/HRex39/rtl8852be.git

Do you have any solution for my Bluetooth?
