I'm not familiar with CollectionC but some of my program used AMSnoop which will receive packets even if it does not belong to its own group. I had to place a filter in this routine to drop the packet. Maybe you have a similar case.

But when I build another CollectionC network in the same room, or another root, nodes of the first network start to send packets to this newest root, despite networks and roots have different Group-IDs. How can i solve this? Any idea or help would be appreciated. Best Regards.
