Hello,
I would like to know what is the best approach for protocol decoder. Is it better to use BinPAC or BinPAC++ ?
When does BinPAC++ will be supported for production?
Thanks
Emmanuel.

I would say it depends on your use case. If it's indeed "production",
then BinPAC. BinPAC++ is still in prototype state. If you're just
experimenting with some protocol though, it can make sense to give it
a try.

Unclear, there's signficant work left. It's at the state where the
research work has concluded and produced a solid prototype, but taking
it to production will require additional resources that we don't have
right now unfortunately.
