sudo apt-get update

sudo apt-get install bluetooth 
sudo apt-get install blueman
sudo apt-get install raspberrypi-sys-mods
sudo apt-get install --reinstall pi-bluetooth
sudo hciattach /dev/ttyAMA0 bcm43xx 921600
sudo usermod -G bluetooth -a pi #这个是登录的用户名

重启 sudo shutdown -r now

sudo systemctl start bluetooth
sudo systemctl start hciuart.service
systemctl status hciuart.service
systemctl status bluetooth.service

启动:

sudo systemctl start bluetooth
systemctl status bluetooth

sudo bluetoothctl

不行的话只能重装系统了
