ZigBee protocol stack Chinese description (148 pages in pdf, welcome to download)[Copy link]
The ZigBee stack is built on the IEEE 802.15.4 standard, which defines the MAC and PHY layers of the protocol. ZigBee devices should include the PHY and MAC layers of IEEE802.15.4 (which defines the RF radio and communication with neighboring devices), as well as the ZigBee stack layers: the network layer (NWK), the application layer, and the security service provider layer. Figure 1-1 gives an overview of these components. 1. ZigBee stack layers Each ZigBee device is associated with a specific template, which may be a public template or a private template. These templates define the application environment of the device, the device type, and the cluster used for communication between devices. Public templates ensure interoperability of devices from different vendors in the same application domain. Devices are defined by templates and implemented in the form of application objects (see Figure 1-1). Each application object is connected to the rest of the ZigBee stack through an endpoint, and they are all addressable components in the device.
