与我的另一篇"Android手机上的OBD II汽车诊断扫描器（ELM327)"(http://bbs.wenxuecity.com/auto/353603.html)一样，文章是自己摸索的结果，更多的问题要读者自己解决。
这篇说的是用PC连接ELM327 蓝牙接口的OBDII，用的是ELM327附带光盘，ELM327是EBAY上买的V1.5版。
先读了一下光盘说明，建议用scantool_net113win，把它装了运行(见图左)，发现它不支持蓝牙。看光盘上有个BlueSoleil，里面有setup.exe，把它装了。要注意的是它安装时似乎把原来的蓝牙驱动都卸了。
运行BlueSoleil|Tools|Find Device, 选search by name，敲入OBDII，按search（图右下），就可以找到一个名为OBDII的设备。BlueSoleil的窗口原来有个红太阳,现在就会加上一颗名为OBDII的行星(见图)。鼠标右键该星，选pair，再选connect(或Tools|Configurations|Quick Connect)，PC就会连接上你已经插在汽车上的ELM327。在这个过程中窗口下的状态行有相应信息显示，而且由行星到太阳增加了一条细的发射线（图右）。
运行ScanTool.net 1.13(见图左)，先在option下配置串口为COM6,9600 Baud。再用sensor data或read code，就可看见OBDII读回的数据。如果不行，在BlueSoleil|Tools|My bluetooth device设置串口同上。不过下次看它又变成USB了，但是不影响连接使用.

补充：我的OBDII是V1.5现在是2.1。在DELL 4200 win7-32上开始连不上，用驱动精灵更新bluetooth驱动，添加bluetooth设备，输入匹配码1234后可连上。Scanmaster扫描可找到，但Test或Connect失败数次，最后连上了。在手机Torque lite不能缺少的两个前级宽带O2现在有了。蓝牙驱动是Broadcom的，Scanmaster声明蓝牙只支持Microsoft/BlueSoleil等无Broadcom。

补充：在Windows上用Droid4X运行Torque，Bluetooth没连上，似乎还是Braodcom驱动问题。网得：

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 .
