Hi.

It looks like there is a misalignment, at some point, why did you choose that packager?

I’m not familiar with Postilion, so I don’t know its log format, the 8408: looks like the last 3 digits of your MTI and the first of the bitmap. I don’t know if that is the MTI read by Postilion or something else, but somehow it is omitting the first byte (1), that looks like a question for the other side or Postilion. The weird thing is that it is showing the first byte in the binary data.

Apart from that, your ISO message XML does not match your code, are you sure that is the same code you used for your test?

Kind regards.
