1 加载蓝牙模块 需要加载的模块有bluetooth、 hci_uart、 l2cap、 rfcomm、 sco、 bnep,位于/lib/modules/`uname-r`/kernel/net/bluetooth 和/lib/modules/`uname -r`/kernel/driver/bluetooth 注:可以使用 bt_ins.sh 与 bt_rm.sh 两个脚本,进行蓝牙模块的添加与删除 #!/bin/bash #name: bt_in.sh #author:young #date: 2007-01-16 #decription: insmod for bt modules insmod /lib/modules/`uname -r`/kernel/net/bluetooth/bluetooth.ko insmod /lib/modules/`uname -r`/kernel/net/bluetooth/l2cap.ko insmod /lib/modules/`uname -r`/kernel/net/bluetooth/sco.ko insmod /lib/modules/`uname -r`/kernel/net/bluetooth/bnep/bnep.ko insmod /lib/modules/`uname -r`/kernel/net/bluetooth/rfcomm/rfcomm.ko insmod /lib/modules/`uname -r`/kernel/drivers/bluetooth/hci_uart.ko lsmod | grep bluetooth #!/bin/bash #name: bt_rm.sh #author:young #date: 2007-01-16 #description: rmmod bt modules from kernel rmmod hci_uart rmmod bnep rmmod sco rmmod rfcomm rmmod l2cap rmmod bluetooth lsmod 2 重启Bluetooth系统服务 # /etc/init.d/bluetooth restart Restarting Bluetooth services: [ OK ] 3 邦定tty设备 # hciattach -n /dev/ttyUSB0 ericsson 57600 & 注: 成功后就不要再次邦定tty设备了 命令hciconfig提供有关本地设备的详细信息。如果不带任何参数执行 hciconfig，则输出将显示设备名 (hciX) 等设备信息、物理设备地址(12位数字，形式为00:12:34:56:78)和有关已传送数据量的信息。hciconfig hci0 name显示当您的计算机接收来自远程设备的请求时它返回的名称。除查询本地设备的设置外，hciconfig还可用于修改这些设置。例如，hciconfig hci0 name TEST 将名称设置为TEST。 # hciconfig –a hci0: Type: UART BD Address: 00:08:AC:03:68:77 ACL MTU: 192:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:925 acl:6 sco:0 events:35 errors:0 TX bytes:488 acl:5 sco:0 commands:22 errors:0 Features: 0xff 0xff 0x8f 0xfe 0x9b 0xf9 0x00 0x80 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'PC159-0' Class: 0x120104 Service Classes: Networking, Object Transfer Device Class: Computer, Desktop workstation HCI Ver: n/a (0x3) HCI Rev: 0xa5c LMP Ver: n/a (0x3) LMP Subver: 0xa5c Manufacturer: Cambridge Silicon Radio (10) 说明：如果没有看到这样的信息，那么确认一下hcid是否正在运行，并在文件/var/log/messages中是否有错误信息。适配器的BD Address是蓝牙识别符的唯一标识，其原理与以太网的MAC地址类似。 4 激活蓝牙模块 # hciconfig hci0 up 5 查看蓝牙模块信息(是否正确被识别,是否工作正常) # hcitool dev Devices: hci0 00:1B:35:00:12:34 6 查询周围蓝牙设备 # hcitool scan Scanning ... 00:E0:91:74:2E:64 KE850 00:08:AC:03:58:A6 DTK001 00:19:2D:61:12:5E N73-MMI 找的蓝牙设备硬件地址与设备名 7 建立虚拟串口设备 # mknod /dev/rfcomm0 c 216 1 # chmod 666 /dev/rfcomm0 需要设置minicom Serial Device : /dev/rfcomm0 8 修改rfcomm.conf,添加如下内容 # vi /etc/bluetooth/rfcomm.conf rfcomm0{ bind no;
