[Optware] 安裝藍牙(BlueZ 2.25)與手機連結
事先說明:
1. 因藍牙棒的種類(晶片)版本不同, 以下安裝藍牙棒的步驟, 或許不能成功. 請詳查錯誤訊息.
2. 因無線頻率都是2.4GHz, 所以暫時關閉WL-500gx無線功能(DD-WRT有選項可與藍牙共存).
3. 若只想玩弄手機, 可到手機官網找AT command, 經由USB直接操控亦可.
4. BlueZ套件另有相關命令, 請自行查閱測試.
5. 有關藍牙的基本概念等, 建議使用Google學術搜尋, 查閱相關論文. 尤其是論文內對藍牙的簡介, 如此才能理解命令執行後, 輸出訊息的涵義.
機型: 華碩 WL-500gx
韌體: CDMA@wifi 1.71
藍牙棒: CG-USB02-01
手機: Sony Ericsson K600i
1. 未載入kernel module前, 插入藍牙棒, 檢查錯誤訊息(dmesg或/tmp/syslog.log)
usb.c: USB device 2 (vend/prod 0x1131/0x1001) is not claimed by any active driver.
2. kernel module來源與安裝
Oleg: 參考站長寫的這篇文章.
CDMA@wifi: 與下載韌體相同的網址.
DD-WRT: 安裝OpenWrt套件: kmod-bluetooth, kmod-bluetooth-hciusb
3. 載入kernel module
$ modprobe -sv bluez
$ modprobe -sv hci_usb
$ modprobe -sv l2cap
$ modprobe -sv rfcomm
$ modprobe -sv bnep
$ modprobe -sv sco
若無modprobe命令, 以insmod取代.
$ insmod -v bluez | logger -s
...
檢查kernel module載入訊息
BlueZ Core ver 2.4 Copyright (C) 2000,2001 Qualcomm Inc
Written 2000,2001 by Maxim Krasnyansky
...
4. 重新插入藍牙棒, 查看kernel能否驅動.
5. 安裝BlueZ套件
因Optware BlueZ 3.36使用上出現Segmentation fault, 原因尚未詳察, 所以安裝BlueZ 2.25
$ ipkg-opt install bluez2-utils
暫不使用啟動檔, 更名之.
$ mv /opt/etc/init.d/S75bluez-utils /opt/etc/init.d/s75bluez-utils
6. 修改HCI daemon設定檔, 暫時關閉認證, 加密. 設定說明請man.
$ vi /opt/etc/bluetooth/hcid.conf
options {
預設值, 不變
}
device {
...
#auth enable;
#encrypt enable;
}
7. 修改配對密碼, 原來的BlueZ暫時改為1234
$ vi /opt/etc/bluetooth/pin
1234
8. 啟動HCI daemon
$ hcid -f /opt/etc/bluetooth/hcid.conf
9. 檢查藍牙棒是否啟動.
$ hciconfig -a

$ hcitool scan

11. 手機也掃描WL-500gx, 並輸入配對密碼1234
12. 測試連線, Ctrl+c中斷.

14. 安裝OBEX套件, 以OBEX(OBject EXchange)傳送檔案測試
$ ipkg-opt install openobex
$ ipkg-opt -nodeps install obexftp
$ ipkg-opt install libusb
15. 建立測試文件檔(這部分就不說明了), 傳送到手機
$ obexftp -b 00:16:xx:xx:xx:xx -p test.txt
Browsing 00:16:xx:xx:xx:xx ...
Connecting...done
Sending "test.txt"... done
Disconnecting...done
傳送後, 檢查手機應該就有test.txt文件了.
後續步驟: 設定啟動檔, 修改藍牙相關設定檔等.
DD-WRT: 若JFFS2夠大, 可將kernel model放入flash memory內.
Oleg與CDMA@wifi: 因受限flash.tar.gz只能64K, kernel module要放在USB flash.
後續玩法:
藍牙耳機聽網路音樂, MP3, 網路電話.
Gnokii傳簡訊(目前Optware的Gnokii 0.6.14只支援Nokia舊機型)
3G手機上網
其他天馬行空, 任您想像.
這篇寫的亂了些, 一方面天氣冷
, 腦袋結冰, 一方面是之前的測試紀錄文件, 是由不同的測試環境(操作系統)來理解藍牙的運作(咦, 地震...). 若您想進一步運用藍牙, 建議您在其他Linux操作系統(例如: Mandriva)先測試, 再回頭找Optware相關套件實作. 這樣比較容易成功.

Re: [Optware] 安裝藍牙(BlueZ 2.25)與手機連結
我測試過二支藍牙棒, Integrated System Solution Corp. KY-BT100(CG-USB02-01)(v1.2), Broadcom BCM92045DG Non-UHE(v2.0). 在Optware BlueZ v2.25下還好, 但在Mandriva 2009.0就不是很穩. 照理說, Mandriva的相容性應大於Optware的.
另外, 若藍牙棒插在外接式USB Hub, 而不是WL-500gx的屁屁, 也會出現一些狀況.
