Linux 下使用 Bluetooth USB Dongle

1 加載藍牙模組

需要加載的模組有 bluetooth, btusb, hci_uart, l2cap, rfcomm, sco, bnep, 位於 /lib/modules/`uname-r`/kernel/net/bluetooth 和 /lib/modules/`uname -r`/kernel/driver/bluetooth 裡 

$ make ARCH=arm menuconfig
[*] Networking support  --->

建議:

  1. 可以寫 bt_ins.sh 與 bt_rm.sh 兩個腳本, 進行藍牙模組的添加與刪除
  2. 模組是有相依性的, 請注意順序
    [root@fedora14 ~]# lsmod
Module                  Size  Used by
rfcomm                 54383  4
sco                    13825  2
bnep                   11942  2
l2cap                  43256  16 rfcomm,bnep
btusb                  12562  2
bluetooth              73201  9 rfcomm,sco,bnep,l2cap,btusb
rfkill                 13580  2 bluetooth
...
  3. 因 bluetooth.ko 須 rfkill.ko, 所必要時先 insmod rfkill.ko
#!/bin/bash
#name: bt_in.sh

2. Install Bluez

Bluez is the Official Linux Bluetooth protocol stack (http://www.bluez.org/) and you need to install it to do any further action with Bluetooth. This stack is available as standard Debian package with the name bluez-utils so to install it simply type: 

debarm:~# apt-get update
...
debarm:~# apt-get install bluez
...

PS. 新的 bluetooth(系統不認得的)

1. 先得取此 bluetooth 的 VID/PID 

[root@fedora14 ~]# lsusb
Bus 002 Device 004: ID 0a5c:21e8 Broadcom Corp.
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
[root@fedora14 ~]#

在此 0a5c:21e8 Broadcom Corp. 即為我們的 VID/PID(0a5c/21e8)

2. 將此VID/PID加入 btusb 內

改 kernel source, {src}/drivers/bluetooth/btusb.c 

static struct usb_device_id btusb_table[] = {
        /* Generic Bluetooth USB device */
        { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },
        .
        .
        .
        /* Broadcom BCM20720A0 */
        { USB_DEVICE(0x0489, 0xe042) },
        { USB_DEVICE(0x0a5c, 0x21e3) },
        { USB_DEVICE(0x0a5c, 0x21e6) },
        { USB_DEVICE(0x0a5c, 0x21e8) },
 
        { }     /* Terminating entry */
};

3. make modules 並複制到系統 modules 目錄內 

[root@fedora14 linux-2.6.35.6]# make modules
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CC [M]  drivers/bluetooth/btusb.o
  Building modules, stage 2.
  MODPOST 2233 modules
WARNING: modpost: Found 7 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
  CC      drivers/bluetooth/btusb.mod.o
  LD [M]  drivers/bluetooth/btusb.ko
[root@fedora14 linux-2.6.35.6]# cp drivers/bluetooth/btusb.ko /lib/modules/2.6.35.6/kernel/drivers/bluetooth/btusb.ko
cp: overwrite `/lib/modules/2.6.35.6/kernel/drivers/bluetooth/btusb.ko'? y
[root@fedora14 linux-2.6.35.6]#

4. OK~
