[riot-devel] Communication among running RIOT board (native) and unix application

[Nazmul Alam]

Hello,
I am new to RIOT and trying to run it in native system. I would like to
know if it is possible to add another tap interface to the bridge to
monitor two native application's packet transaction and their contents?

I want to communicate with an ipv4 based socket application with one of the
running RIOT image. Will it be possible if I add an address to each of the
images? or do I need another image as the border router to facilitate the
connection between them?

Thanks in advance.

with best regards,

OpenThread doesn't use IPv6 neighbour discovery, they use a forked MLE
protocol which is maybe ~80% of that what IETF MLE is. They use MLE for
neighbour discovery, means filling neighbour entries with that. Also I
saw that they broadcast a stateful compression CID over MLE. The rest I
currently try to detect by using the force, ehm source.

Also you cannot be sure that OpenThread really follow any IETF standard
and do they own forks. Please see my question [0].

So OpenThread 6LoWPAN is _maybe_ not IETF 6LoWPAN.

The problem with TCP jokes is that people keep retelling them slower until you

Re: [riot-devel] BorderRouter: Global IPV6 address lost in ncache after UDP message sent

[Baptiste Clenet]

Thanks Martine,
The issue you mentioned seems to be different.

Did you see the neighbor discovery implementation of OpenThread? How
your new implementation will be able to dicuss with OpenThread
implementation?

Cheers,
