OK, this is strange. LGT+WRX says he has both versions working on a 16-bit ecu but can't get them to work on a DBW, while jackyyuen says 0.02 works on DBW but not 0.03.
I was under the impression that SSM datalogging should work the same for 16-bit and DBW ecus but maybe that's not true. Although for jackyyuen it's working on at least one DBW.
As for 0.03 not working while 0.02 does this is strange as well. I'd say I probably broke something but LGT says he has both working at least on a 16-bit ecu.
The only thing that comes to mind at the moment is an issue with the RXTX libraries as I changed their location hoping this would eliminate the need to manually install them. Try following the instructions in the first post to manually install and see if this helps, jackyyuen.
I'm leaving for vacation in the morning so I'm sorry but I probably won't get this fixed for you guys until I get back but I'll take a look tonight and see if it's something obvious that's causing at least one of your problems.
When I get back I'll post a debugging version for you guys to run that should pretty easily let me know whats wrong.
