top Each Node has a unique IEEE and NWK (ZigBee Network Layer) address that is assigned when a node joins the network. Every subunit and thus Application Object in a node is addressed by endpoint number unique within a node. An Application Object receives commands from outside world addressed to pair: (node address, endpoint number). AO commands may be of two types: Key-Value Pair (KVP) and Generic Messages. What types of ZigBee Devices exist in a network? top According to IEEE MAC specification that introduces three device types, ZigBee specifies the following ZigBee Devices: • ZigBee Coordinator (MAC Network Coordinator). Maintains overall network knowledge; most sophisticated of the three types; most memory and computing power • ZigBee Router (MAC Full Function Device: Carries full 802.15.4 functionality and all features specified by the standard). • ZigBee End Device (MAC Reduced Function Device: Carriers limited functionality to control cost and complexity. Also, may be MAC Full F
