As some of you may know, I've written an app called OBDroid for OBD2 datalogging over bluetooth. At the moment it is limited to code scanning/clearing and gauge display, however I am activly looking into logging capabilities for it. There are already provisions for logging built in and working on my test-version, but the issue I'm running into has to do with logging formats. So what would people prefer in the way of how data was logged? There doesn't seem to be a real standard for logged OBD2 data so I'm open to suggestions. I have a desktop OBD2 scanning application which I can add log-reading capabilities to as to allow OBDroid users to view their logs, but I still need a format! An application written by a friend of mine (OBD GPS Logger for Linux and OSX) has a logging format which I could use, that uses SQLite databases and allows you to convert from the database to CSV. This format however also allows for GPS data, and easily can be modified to allow for accelerometer data as well, if there is interest in GPS and Accelerometer datalogging along with obd2. Any thoughts/opinions?
