but I get what you're saying.
Curtis supports some J1939 messages via canbus and PID's. It's really not the adapter as much as the software that is running on your device (desktop, laptop, etc). The one's I've looked at seem to pass everything through to the canbus, it doesn't filter messages. That gets done in the software, which at this point, isn't written for the Curtis.
I'd love to work with people on this, I've got some ideas.
So does J1939 cover the actual messages themselves, or just the message format?
OK, found this on wikipedia "A PGN identifies a message's function and associated data. J1939 attempts
to define standard PGNs to encompass a wide range of automotive, agricultural, marine and off-road vehicle purposes. A range of PGNs (00FF0016 through 00FFFF16, inclusive) is reserved for proprietary
Use of bold is mine to highlight what I said above. Also apparently J1939 did not original include CAN, but does now.
CANBus is like a telephone. You can use a phone to make a connection to someone in France, but unless you can speak French or they can speak English you're not going to be able to communicate.
