[vivek]

My laptop HP Probook 450 g0 has a bluetooth device. But my Ubuntu 20.04 can't find this device.

I tried
dmesg | grep -i blue -> No output

I know my laptop has bluetooth device for sure.

You can try rtbth-dkms from https://launchpad.net/~blaze/+archive/ubuntu/rtbth-dkms
I don't think the RT3290 ever had bluetooth support in the kernel

Thanks, it solved my problem.

I installed this package by,

sudo add-apt-repository ppa:blaze/rtbth-dkms
sudo apt-get update
sudo apt-get install rtbth-dkms

And then,

sudo modprobe rtbth

It worked.
