Coordinator's data transmission method, device's data reception method, coordinator using the coordinator's data transmission method, and device using the device's data reception method in Zigbee system

摘要

A coordinator's data transmission method, a device's data reception method, a coordinator using the coordinator's data transmission method and a device using the device's data reception method are provided. In a Zigbee system including at least one device and a coordinator for coordinating the device, in a case where a frame pending bit in a beacon frame is determined to be a value representing a direct transmission method, a beacon frame containing an address of a device to receive data and a data transmission time is generated and data is transmitted from the coordinator at the data transmission time. Data transmission time and power consumption can be reduced.
