Max,

At my level of understanding of CoAP, which is very low, this seems
to make sense. I do have a couple of questions, which probably betray
my ignorance:

1. Is CoAP/DTLS protected against corrupt packets? (Assuming we are
talking about UDP/IPv6 there will at least be the UDP checksum.)

2. In the fragmentation scenario, what happens when a fragment is
corrupted or lost?

Regards
   Brian
