與我的另一篇"Android手機上的OBD II汽車診斷掃描器（ELM327)"(http://bbs.wenxuecity.com/auto/353603.html)一樣，文章是自己摸索的結果，更多的問題要讀者自己解決。
這篇說的是用PC連接ELM327 藍牙接口的OBDII，用的是ELM327附帶光盤，ELM327是EBAY上買的V1.5版。
先讀了一下光盤說明，建議用scantool_net113win，把它裝了運行(見圖左)，發現它不支持藍牙。看光盤上有個BlueSoleil，裏麵有setup.exe，把它裝了。要注意的是它安裝時似乎把原來的藍牙驅動都卸了。
運行BlueSoleil|Tools|Find Device, 選search by name，敲入OBDII，按search（圖右下），就可以找到一個名為OBDII的設備。BlueSoleil的窗口原來有個紅太陽,現在就會加上一顆名為OBDII的行星(見圖)。鼠標右鍵該星，選pair，再選connect(或Tools|Configurations|Quick Connect)，PC就會連接上你已經插在汽車上的ELM327。在這個過程中窗口下的狀態行有相應信息顯示，而且由行星到太陽增加了一條細的發射線（圖右）。
運行ScanTool.net 1.13(見圖左)，先在option下配置串口為COM6,9600 Baud。再用sensor data或read code，就可看見OBDII讀回的數據。如果不行，在BlueSoleil|Tools|My bluetooth device設置串口同上。不過下次看它又變成USB了，但是不影響連接使用.

補充：我的OBDII是V1.5現在是2.1。在DELL 4200 win7-32上開始連不上，用驅動精靈更新bluetooth驅動，添加bluetooth設備，輸入匹配碼1234後可連上。Scanmaster掃描可找到，但Test或Connect失敗數次，最後連上了。在手機Torque lite不能缺少的兩個前級寬帶O2現在有了。藍牙驅動是Broadcom的，Scanmaster聲明藍牙隻支持Microsoft/BlueSoleil等無Broadcom。

補充：在Windows上用Droid4X運行Torque，Bluetooth沒連上，似乎還是Braodcom驅動問題。網得：

Download Androidx86 from this This is an iso file, so you'd need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux instead of Other. · After creating the virtual machine, set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot. · Now you need to find out the ip of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this. ·
Now you need open a command prompt and go to your android install folder (on host). This is usually C:Program FilesAndroidandroid-sdkplatform-tools>. · Type adb connect IP_ADDRESS · There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device. · In VirtualBox screen, go to Devices>USB devices. Select your dongle. ·
Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices. · Now all that remains is to go to Eclipse, and run your program. The Android AVD manager should show the VM as a device on the list.
Alternatively Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .
