安装蓝牙驱动程序：

sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco \
bluez-compat bluez-cups bluez-dbg bluez-gstreamer bluez-hcidump \
bluez-pcmcia-support bluez-tools bluez-utils python-bluez \
bluewhoindicator-bluetooth libbluetooth-dev  libgnome-bluetooth11 libbluetooth3

编辑rc.local文件 -

sudo nano /etc/rc.local

添加以下行 -

rfkill unblock bluetooth

重新启动系统并再次检查。
