Zigbee Cluster Library

The Zigbee Cluster Library (ZCL) is a set of common clusters and cross-cluster commands used in
application profiles.
The Zigbee Cluster Library groups the clusters in functional domains, such as General, Measurement
and sensing, and Lighting. Clusters from these functional domains are used in the Zigbee Public
Profiles to produce device descriptions, such as an on/off switch, a thermostat, or a dimmable light.
Each Public Profile may also define its own specialized clusters, such as the Smart Energy Price
Cluster.
The Zigbee Cluster Library is released under its own specification, separate from the Zigbee
specification. Go to

Zigbee Device Object (ZDO)

The Zigbee Device Object (ZDO) is an application object responsible for initializing the Application
Support Sublayer (APS), Network Layer (NWK), and Security Service Provider (SSP). It runs on the
reserved endpoint 0 in every Zigbee device.
ZDO is typically required when developing a Zigbee product that interoperates in a public profile such
as Home Automation or Smart Energy, or when communicating with Zigbee devices from other
vendors. The ZDO can also be used to perform several management functions such as frequency
agility, discovering routes and neighbors, and managing device connectivity.
The application profile defined for ZDO is the Zigbee Device Profile (ZDP), which has an application
profile identifier of 0x0000. ZDP is a management and discovery service layer supported on all Zigbee
devices. Like all other profiles, it defines a set of services that perform a variety of advanced network
management and device and service discovery options.
