Linux下Bluetooth的使用

1. 激活設備

首先要有一個藍牙適配器，這個不用說，一般都是USB接口類型。

lsusb               查看系統中連接的藍牙設備
hciconfig           查看設備的詳細信息
hciconfig hci0 up   將設備激活

2. 配置bluez

配置文件位於目錄/etc/bluetooth

3. bluetooth服務

/etc/rc.d/init.d/bluetooth stop
/etc/rc.d/init.d/bluetooth start

4. 掃描設備

hcitool scan

通過以上命令可以查找周圍的Bluetooth設備

5. 綁定設備

有兩種方式來綁定目的藍牙設備
@1 修改/etc/bluetooth/rfcomm.conf
@2 rfcomm bind /dev/rfcomm0 XX:XX:XX:XX:XX:XX

解除綁定方法是
# rfcomm unbind /dev/rfcomm0 BD_ADDR channel

tip: 如果沒有虛擬串口設備(rfcomm0)，則需要手動創建(rfcomm_create_dev?)

# mknod /dev/rfcomm0 c 216 1
# chmod 666 /dev/rfcomm0

6. 添加通道

sdptool add --channel=1 DID SP DUN LAN FAX OPUSH FTP HS HF SAP NAP GN PANU HID CIP CTP A2SRC A2SNK SYNCML NOKID PCSUITE SR1

後面的參數表示系統支持的全部服務

7. 連接設備

hcitool cc XX:XX:XX:XX:XX:XX

8. 發送文件

obex-send *.*
