加载蓝牙驱动模块：insmod ~/test/modules/aic_btusb.ko

添加messagebus用户和组：

（系统用户，且不可登录。-S表示编号从100开始）

addgroup -S messagebus

adduser -G messagebus -SDH messagebus

启动dbus-daemon进程：

rm /opt/bluez/var/run/dbus/pid

/opt/bluez/bin/dbus-daemon --system

复制配置文件：cp ~/bluetooth/dbus-1/system.d/bluetooth.conf /opt/bluez/share/dbus-1/system.d/

（不复制的话无法启动bluetoothd后台进程，会报D-Bus setup failed: Connection ":1.0" is not allowed to own the service "org.bluez" due to security policies in the configuration file的错误）

启动bluetoothd后台进程：LD_LIBRARY_PATH=/opt/bluez/lib /opt/bluez/libexec/bluetooth/bluetoothd &

打开蓝牙：LD_LIBRARY_PATH=/opt/bluez/lib /opt/bluez/bin/bluetoothctl power on

扫描蓝牙设备：LD_LIBRARY_PATH=/opt/bluez/lib /opt/bluez/bin/bluetoothctl scan on
