[ FIX ] Ubuntu 20.04 Bluetooth doesn't Turn On

1. 터미널에 아래 두 개의 명령어만 치면 됨.

sudo rmmod btusb

sudo modprobe btusb

2. 만약 블루투스가 on 되지 않을때

# 상태를 확인해본다.
sudo systemctl status bluetooth

나의 경우
Failed to set mode: Blocked through rfkil

메세지가 있었음.

2-1. 해결법링크(https://askubuntu.com/questions/1340713/bluetooth-service-failed-to-set-mode)

sudo systemctl stop bluetooth
sudo systemctl status bluetooth
sudo systemctl restart bluetooth
