Hi Rodrigo,

I am not sure to understand your comment.

·         Ack-Always mode: ACK is send after each fragmented packet

·         Ack-On-Error: ACK is send after each fragmentation session to indicate to the sender that reconstruction is ok (C=1) or not (C=0) or may reply an ACK with missing tiles at the end of a windows as per draft-ietf-lpwan-ipv6-static-context-hc-21 §8.4.3.2.  Receiver behaviour

So, could you please clarify ?


Best regards
Olivier
