I would prefer to have this as out of tree project, so we could add CI
pipeline to it for improved QA.

It would be nice to get rid of all those magic numbers as well, there is a lot
of them.

Ideally the command bytes offsets should be defined (via some enum?) as well,
so it's easier to review the code otherwise one would need to keep in head,
that byte 11 is CRC etc.

ULOG_DBG ?

ULOG_ERR ?
