The coordinator is the organizer of network management. In many commonly used modes, any ZigBee can only be connected to one coordinator, and it should first select its own channel and ID, and gradually downwards, the coordinator and router communicate with each other , And these terminals should be in the same area; then the router will be responsible for more scenic spots and the network equipment responsible for connecting multiple areas, but in many cases will be responsible for external network communication, the coordinator can be used as the beginning of the entire network, so it Has the greatest control of the entire network, and is also the guardian of the entire network. It can maintain the binding of the indirect address form, but it can design the security center and even perform different behaviors. After the Zigbee network is formed, the coordinator does not necessarily need it. The coordinator can also be the main node, but it should be noted that a network can only have one coordinator to manage other nodes in the network.
