We are using Microchip's latest ZigBee development kit & are esperienceing problems. The simplest failure happens when the connection gets dropped between a single receiver / tranmitter pair. Once the connection is dropped, the connection never gets reestablished, no matter how close the receiver / transmitter pair. The lowest level of the Zigbee stack is enabled & none of the higher levels is turned on.
This appears to be a software problem in Microchip's root level ZigBee stack.
Any feedback would help.
