Archlinux下配置蓝牙

安装 bluez-utils工具包，以确保一下命令可用：
hciconfig;hcitool;sdptool;obex_test

安装蓝牙工具包：
#pacman -S bluez-utils

然后使用一下命令查看蓝牙设备：
#hciconfig -a
hci0: Type: USB
BD Address: 00:23:4D:F6:7A:04 ACL MTU: 1021:8 SCO MTU: 64:1
  UP RUNNING
    RX bytes:9292 acl:168 sco:0 events:220 errors:0
    TX bytes:3331 acl:134 sco:0 commands:65 errors:0
    Features: 0xff 0xff 0x8f 0xfe 0x9b 0xff 0x79 0x83
    Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
    Link policy:
    Link mode: SLAVE ACCEPT
    Name: 'ThinkPad Bluetooth 2.1 with Enhanced Data Rate'
    Class: 0x000000
    Service Classes: Unspecified
    Device Class: Miscellaneous,
    HCI Ver: 2.1 (0x4) HCI Rev: 0x518f LMP Ver: 2.1 (0x4) LMP Subver: 0x424c
    Manufacturer: Broadcom Corporation (15)
如果蓝牙设备的状态为down，需要将该设备启动；
#hciconfig hci0 up
查看附近的蓝牙设备：
#hcitool  scan
Scanning ...
    00:1F:5D:87:0C:40    Ruby
根据一下命令查看一下OBEX Object Push服务是否存在：
#sdptool search OPUSH
Inquiring ...
Searching for OPUSH on 00:1F:5D:87:0C:40 ...
Service Name: OBEX Object Push
Service RecHandle: 0x10098
Service Class ID List:
  "OBEX Object Push" (0x1105)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 9
  "OBEX" (0x0008)
Language Base Attr List:
  code_ISO639: 0x656e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "OBEX Object Push" (0x1105)
    Version: 0x0100
根据以上显示的Channel号9，输入一下命令：
#obex_test -b 00:1F:5D:87:0C:40 9
Using Bluetooth RFCOMM transport
OBEX Interactive test client/server.
> c
Connect OK!
Version: 0x10. Flags: 0x00
> p a
PUT file (local, remote)> a a
name=a, size=18
Going to send 18 bytes
PUT successful!
这样在Archlinux下配置bluetooth就初步成功了！！！

可参考一下脚本：bt
#!/bin/bash
# Version:0.1
# --------------------------------
# root user to run this script
# --------------------------------
if [ $UID -ne 0 ];then
    echo "Must be root to run! "
    exit 9
fi
# --------------------------------
# get bluetooth name & status
# --------------------------------
BTName=$(hciconfig|sed -n '1p' |awk -F':' '{print$1}')
BTStatus=$(hciconfig |sed -n '3p'|tr [a-z] [A-Z])

# --------------------------------
# start up the bluetooth
# --------------------------------
if [ "$BTStatus" == "DOWN" ];then
    #echo "++++"
      hciconfig $BTName up >/dev/null
      if [ $? -ne 0 ];then
            echo "Start bluetooth failed!"
            exit 9
      fi
fi
# --------------------------------
# get other bluetooth by scanning
# --------------------------------
ScanBT=$(hcitool scan|grep -v "Scanning"|awk '{print$1}')
ChannelNumber=$(sdptool browse $ScanBT|awk 'BEGIN{FS=":"}{
if($0~/Service Name: OBEX Object Push/){
    getline;
    while($0!~/Channel:/){
        getline;}
        {print$2}
}
}'
)
#echo "Channel Number : $ChannelNumber"
# --------------------------------
# transformer the file on obex protocol
# --------------------------------
obex_test -b $ScanBT $ChannelNumber

另总结的配额linux bluetooth步骤：
# 1: hciconfig wlan0 up
# 2: hcitool scan
# 3: sdptool browse DEV
# 4: rfcomm bind /dev/rfcomm0 DEV 9
# 5: ussp-push /dev/rfcomm0 local_file remote_file
