Streaming and CAN

[Cayce Williams]

Hello OpenXC forum.

I was wondering if someone could tell me If I found a bug in the firmware.

I wrote a standalone application for OpenXC on the computer.

When I do this:

connect()
startStream()

Everything works as intended.

However if I perform this operation:

connect()
wait(500)
startStream()

The OpenXC sends a few messages and then stops. 

If I attempt to disconnect from the device it remains in a connected state and I have to reset it manually.

I am using Java & Bluecove for Bluetooth. I use some of the same boilerplate from android for translating the stream into JSON.

Has anyone come across this or might know what the issue is?

Second:

As the OpenXC advertises it is available for any car past 1996. 

However I believe that is only if you know the CAN BUS information.

Such as 

HS/LS

Message IDs

Bit position

etc...

Is there any standard way to obtain this information besides using a can bus listener and filtering out repeated IDS in a spread sheet?

Or do we just have to be lucky enough to wait for the automotive company's to release this information?

How is it that a company like CalAMP has a swiss army knife of OBD's and can work in any car with one firmware provided?

Thanks in advance

Is there anyone who can throw me a bone on this one?
