I bought an elm327 obd reader to interface my car with my arduino. I got a USB one, the only alternative I could find was Bluetooth. It seemed to have the same pinouts as the one on this site.
But after trying it I find it does not work. Then I noticed mine has a chip not on the one on that site, a FT232RL USB bridge. So that must be a problem. I was hoping it was possible to use the FT232RL datasheet
to locate what traces on my device are the serial lines so I can still use it. I assume they would be pins TXD and RXD but I've got no clue really.
I would appreciate any kind of help... Thanks
