In the ZigBee network, three network roles are defined, namely Coordinator (Network Coordinator Node), Router (Network Router Node), and End Device (Network Endpoint Node).

The RRadioland ZigBee module currently includes 2530A1, 2530A2, 2530PA1, 2530PA2 and related mating boards. It is based on TI's CC2530F256 chip and runs ZigBee module of ZigBee2007/PRO protocol. It has all the features of ZigBee protocol, which is different from other types. The ZigBee module (may not run the Full ZigBee2007 protocol, because the ZigBee2007 protocol requires 256K of FLASH space to run).

ZigBee is a low-rate, short-range technology. This feature determines that ZigBee is not suitable for fast transmission and long-distance transmission.

This phenomenon does exist: when a Zigbee network is successfully built, Coordinator creates the network.

(Any single-chip microcomputer, as long as it has a serial port (or IO port analog serial port), can be used together with the ZIGBEE transparent transmission module.
