Is there a setup instruction that explains how to setup using XCTU a simple Zigbee network (one AT coordinator and one AT router).The XCTU program is more GUI friendly but no matter what I do, I could not get on XSTICK configured as AT coordinator to communicate another XSTICK configured as AT router. I tried making the DH/DL but still the data from coordinator not showing up on router as serial console is monitored. The is no document on setting a simple network of two device so beginner can learn.
Have you tried the product manual or http://knowledge.digi.com/articles/Knowledge_Base_Article/Range-Testing-with-a-ZigBee-Mesh-Network ?
Try restoring everything to defaults then issue a local network reset on the Coordinator and then Router (ATNR0)
