I will search deeper I see you as well on the RIOT mailinglist. Do you has these issues with RIOT? You can check it with fakelb and bsd-netcat and create/connect udp v6 socket, if it works with a linux<->linux connection, otherwise something is wrong with interoperability (which you can might debug via sniffing). I know they have recently added the rfc6282 udp nhc compression, see [0]. We have nhc_udp enabled by default, (receive handling should have a always possible strategy). Usually you can disable UDP NHC by unloading the "nhc_udp" module if you built it as module. But then you can also not receive anymore other udp nhc iphc headers. To make a fine granularity setting to the nhc strategy, we need a userspace tool and interface for that. - Alex [0] https://github.com/RIOT-OS/RIOT/pull/4189
