Using XBee 900 modules configured for sleepy meshing, we're preparing for installation with basic requirement is that we have at least two hops in a grid of separated sensors. It appears that we're not getting the desired two hops. The configuration involves a node which is sufficiently far from the coordinator to be out of range. If a node is placed roughly midway between the node and the coordinator, things work as expected But if two routers are in range of the node, then messages get through with difficulty, if at all. So routing is possible through any of the two routers, but not at the same time. One idea is that a three-hop route is created, which is failing to work.
Should odd behaviour like this happen with xbee networks?
