工具使用：
bluetoothd完成蓝牙hci层的统一管理服务端
bluetoothctl 蓝牙服务控制，通过dbus与bluetoothd通信
obexd蓝牙文件传输协议接收服务端，通过dbus与bluetoothd通信
hciconfig，hcitool 蓝牙hci层控制工具
obex_test蓝牙文件传输客户端，支持点对点蓝牙的文件发送与接收
sdptool 蓝牙从设备profile服务扫描工具
# 建立串口和蓝牙hci协议层的数据连接通道，usb方式不用
hciattach /dev/ttyAMA0 bcm43xx 921600 noflow -
hciconfig hci0 up
hcitool scan
hciconfig hci0 sspmode disable #关闭简易配对模式,有这个模式的被配对方就不用点击确认
# 查找目标mac蓝牙服务，文件传输服务为"OBEX Object Push" (0x1105)，找出服务所在信道
sdptool brower F4:63:1F:D8:E0:89
# 蓝牙应用层使用工具
bluetoothctl
power on -- 启动蓝牙模块
agent on -- 蓝牙模块agent 打开
scan on -- 扫描周边设备，得到手机MAC：DC:09:4C:62:B3:CA
trust DC:09:4C:62:B3:CA -- trust该手机
pairable on -- 配对使能
discoverable on -- 开放检测
show -- 查看蓝牙配置信息
echo "power on" | bluetoothctl
echo "agent on" | bluetoothctl
echo "pairable on" | bluetoothctl
echo "discoverable on" | bluetoothctl
echo "show" | bluetoothctl
# obex_test发送文件
obex_test -b F4:63:1F:D8:E0:89 5
# obexd开启obex服务，接收文件
export DBUS_SESSION_BUS_ADDRESS="unix:path=/var/run/dbus/system_bus_socket"
