Hi
I tried your fix Dan and it seems not to work. I am running on popOs
19.04 (Dell latitude E6530 i7)
kernel vers: Linux 5.0.0-25-generic x86_64
$ sudo apt-cache policy bluez
bluez:
Installed: 5.50-0ubuntu2+bug1759836v20190827b1~disco
from top:
488 root 20 0 66264 51564 3208 R 100.0 0.4 18:10.64 systemd-udevd
I previously disabled the bluetooth in the bios.
This is my .rules file (after the update):
# do not edit this file, it will be overwritten on update
