I did not use bluetooth on a
Linux system before, but I would like to use it right now. I tried to use it and it didn't work at all. Here are some information:
dmesg | grep -i bluetooth

I have tried editing the .config file as suggested by user Goro below. I have also uninstalled Blueberry and installed Blueman in hopes that it might work. I have googled extensively and found that a lot of users face similar issues that correct themselves after a reboot. This hasn't happened in my case. My kernel is updated to the latest one offered under Software Manager.
EDIT: I think bluetooth has been discontinued for kernel 4.15 and newer. I read it someplace. Anyway, it still doesn't work and I'm giving up now.
