Hi PaulS
Yes I'm using Xbee in AP2 mode.
I'm having no problems sending bytes from end node to coordinator.
Problems starts when I want receive bytes from 3 different endnodes, data crashes. I don't know what field in coordinator to put the address for end node into.
The book is based on series2/zigbee, haven't found what I'm looking for there. If its there please point me in the right directions.
