I have one coordinator, 1 router and 2 end devices, E1 and E2. I want to configure mesh network. router is the parent node of my both end devices. I want to send data from coordinator --> end device E1 via router. So should I send data to router and it will also send to child end device or I send data to end device directly and router will take care of it. I am working in API mode using java. I am newbie and little bit confused.
To your end device of course, as long as your end device in the coordinator range it gona receive its packets, other wise the router gona receive and reroutes the packets for desired node.
