UBUNTU下面有個gnome藍牙桌面管理器，使用起來很簡單，但是搞不清除這個工具的工作細節，看看下面的方法，用的是bluez提供的工具，寫成的腳本，我好好研究研究，以備做嵌入式之用。
1 加載藍牙模塊
需要加載的模塊有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

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

#description: rmmod bt modules from kernel
rmmod hci_uart
rmmod bnep
rmmod sco
rmmod rfcomm
rmmod l2cap
rmmod bluetooth
lsmod
2 重啓Bluetooth
系統
服務
# /etc/init.d/bluetooth restart
Restarting 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，形式爲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 將名稱設置爲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)
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，其原理與以太網的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 dev
Devices:
hci0 00:1B:35:00:12:34
6 查詢周圍藍牙設備
# 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
找的藍牙設備硬件地址與設備名
7 建立虛擬串口設備
# mknod /dev/rfcomm0
c 216 1
# chmod 666 /dev/rfcomm0
需要設置minicom
Serial 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
11 連接設備
# hcitool cc 00:08:AC:03:58:A6

hciattach - attach serial devices via UART HCI to BlueZ stack
---------------------------------------------------
hciattach [-n] [-p] [-t timeout] tty type|id speed flow bdaddr
-n
Don''t detach from controlling terminal.
tty
This specifies the serial device to attach. A leading /dev can be omitted. Examples: /dev/ttyS1 ttyS2
type|id
The type or id of the Bluetooth device that is to be attached,i.e.
vendor or other device specific identifier. Currently supported types
are
type description
any Unspecified HCI_UART interface, no vendor specific options
ericsson Ericsson based modules
digi Digianswer based cards
xircom Xircom PCMCIA cards:Credit Card Adapter and Real Port Adapter
csr CSR Casira serial adapter or BrainBoxes serial dongle(BL642)
bboxes BrainBoxes PCMCIA card (BL620)
swave Silicon Wave kits
bcsp Serial adapters using CSR chips with BCSP serial protocol
Supported IDs are (manufacturer id, product id)
0x0105, 0x080a
Xircom PCMCIA cards:Credit Card Adapter and Real Port Adapter
0x0160, 0x0002
BrainBoxes PCMCIA card (BL620)
speed
The speed specifies the UART speed to use. Baudrates higher than
115.200bps require vendor specific initializations that are not
implemented for all types of devices. In general the following speeds
are supported:
9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600
Supported vendor devices are automatically initialised to their respective best settings.
