I've been trying to use labview with standard firmware for nxt to nxt coms but it is far too slow- I have two nxt's controlling two sets of three legs (so that is 3 master to slave mailboxes and three slave to server mailboxes). With standard firmware this coms is far to slow about 1/4 of a sec for all to catchup from slave to server. Seems that slave to master is not proactive like master to slave is and the master will check it's mail boxes when the lego firmware designers felt would be a good time and that as it turns out is very slow.

What I want to know is how robotc handles this? can a slave act as a master as well? it the timings controllable?

many thanks

Rob
