3.2.6 ZigBee Device type

There are three types of logical devices in the ZigBee network: Coordinator, Router, End-Device (Non-dormant
terminal) and Sleep- End-Device (Dormant terminal). ZigBee network consists of a Coordinator, multiple Routers, and
multiple End Devices (its terminal nodes can be divided into dormant and non-dormant terminals).
3.2.6.1 Non-dormant terminal
The main task of a terminal device is to send and receive messages. No other nodes are allowed
to connect to the terminal device. Non-dormant terminal is always in operating mode and can receive
and send data at any time.
3.2.6.2 Dormant terminal
When wireless data needs to be sent or command operations needs to be performed, wake-up frame needs to be sent
through the serial port first, and the length needs to be 25 bytes or more ("FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF "25-byte" FF "wake-up), the wake-up time lasts 1000ms, during which serial port data
(configuration commands, payload) can be processed, and when a frame of serial port data is successfully received, the
timeout counter will be refreshed, and the wake-up duration will be 1000ms later, otherwise the device will enter sleep
again;
When data needs to be received, it is received through periodic wake-up. The longer the wake-up period is set, the
more the reception is delayed. The wake-up period must be set to less than 30 seconds.
