As far as I know that in digimesh the xbees decide the path and usually it is the shortest possible path. Now if suppose, I want to design a path, how should I approach? I mean, if I want to design a path that is with less traffic rather than lesser distant - will I be able to do that? If yes, then how?
No you do not have that ability. but if you did, I suspect it would be done with the API interface and Source routing.
