linux下使用藍牙設備 bluetooth hciconfig hcitool

1 載入藍牙模塊

需要載入的模塊有bluetooth、 hci_uart、 l2cap、 rfcomm、 sco、 bnep,位於/lib/modules/`uname-r`/kernel/net/bluetooth 和/lib/modules/`uname -r`/kernel/driver/bluetooth注:可以使用 bt_ins.sh 與 bt_rm.sh 兩個腳本,進行藍牙模塊的添加與刪除#!/bin/bash#name: bt_in.sh#author:young#date: 2007-01-16#decription: insmod for bt modulesinsmod /lib/modules/`uname -r`/kernel/net/bluetooth/bluetooth.koinsmod /lib/modules/`uname -r`/kernel/net/bluetooth/l2cap.koinsmod /lib/modules/`uname -r`/kernel/net/bluetooth/sco.koinsmod /lib/modules/`uname -r`/kernel/net/bluetooth/bnep/bnep.koinsmod /lib/modules/`uname -r`/kernel/net/bluetooth/rfcomm/rfcomm.koinsmod /lib/modules/`uname -r`/kernel/drivers/bluetooth/hci_uart.kolsmod | grep bluetooth#!/bin/bash#name: bt_rm.sh#author:young#date: 2007-01-16#description: rmmod bt modules from kernelrmmod hci_uartrmmod bneprmmod scormmod rfcommrmmod l2caprmmod bluetoothlsmod

2 重啟Bluetooth系統服務

# /etc/init.d/bluetooth restartRestarting Bluetooth services: [ OK ]

3 邦定tty設備

# hciattach -n /dev/ttyUSB0 ericsson 57600 & 注: 成功後就不要再次邦定tty設備了 命令hciconfig提供有關本地設備的詳細信息。如果不帶任何參數執行 hciconfig，則輸出將顯示設備名 (hciX) 等設備信息、物理設備地址(12位數字，形式為00:12:34:56:78)和有關已傳送數據量的信息。hciconfig hci0 name顯示當您的計算機接收來自遠程設備的請求時它返回的名稱。除查詢本地設備的設置外，hciconfig還可用於修改這些設置。例如，hciconfig hci0 name TEST 將名稱設置為TEST。# hciconfig –ahci0: 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) 說明：如果沒有看到這樣的信息，那麼確認一下hcid是否正在運行，並在文件/var/log/messages中是否有錯誤信息。適配器的BD Address是藍牙識別符的唯一標識，其原理與乙太網的MAC地址類似。

4 激活藍牙模塊

# hciconfig hci0 up

5 查看藍牙模塊信息(是否正確被識別,是否工作正常)

# hcitool devDevices: hci0 00:1B:35:00:12:34

6 查詢周圍藍牙設備

# hcitool scanScanning ... 00:E0:91:74:2E:64 KE85000:08:AC:03:58:A6 DTK001 00:19:2D:61:12:5E N73-MMI找的藍牙設備硬體地址與設備名

7 建立虛擬串口設備

# mknod /dev/rfcomm0 c 216 1# chmod 666 /dev/rfcomm0需要設置minicomSerial Device : /dev/rfcomm0

8 修改rfcomm.conf,添加如下內容

# vi /etc/bluetooth/rfcomm.conf rfcomm0{ bind no; device -00:1B:35:00:12:34; channel 1; comment "HCI003"}說明: bind no 是設置是否自動綁定設備; device -是設置綁定設備的地址; channel 是設置設備的通道; comment 是對設備的描述。注意:這個device的地址是本地藍牙設備的地址。

9 添加sdp協議通道

# 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說明:後面的參數不一定全部支持,簡單起見默認將服務全部打開。

10 使用虛擬串口與外界藍牙設備綁定

格式:# rfcomm bind /dev/rfcomm0 藍牙設備地址通道# rfcomm bind /dev/rfcomm0 00:08:AC:03:58:A6 -1藍牙設備地址: 遠端藍牙設備地址(DTK001)如果需要解除綁定# rfcomm unbind /dev/rfcomm0 BD_ADDR channel
