I am trying to implement two way communication between two Series 2 ZB modules, one set as Coordinator API and the other set as Endpoint API using the next get XCTU.
When I send unicasts from the endpoint with the destination address set to the coordinator address (0x00000000) they arrive fine. Same if I set it to the MAC of the coordinator.
If I send unicasts from the Coordinator with the destination address set to the MAC of the endpoint they don't arrive. Nothing is shown in the console for the endpoint. If I do the same with a broadcast destination address (0x00 00 00 00 00 00 FF FF) it arrives at the endpoint fine.
I'm not sure what config options would be relevant so say what you need to know and I'll provide. Thanks in advance for help.
