Hi Bern,
Brice's branch (master) hasn't been updated for some time now. I only managed to get it compiling with Maven. Now, branch dev-1_3 is the most updated code so far and it solves a bunch of issues some people complain about when testing the old code.
Regarding OBD commands that one can implement, it's as easy as to check the 'obd-api' source (branch dev-1_3) and implement as you see fit.
I'll be merging the changes into master today and update the project's page to match the current state.
Cheers,
PP
