DATA TRANSMISSION METHOD INDICATING DATA PENDING IN ZIGBEE NETWORK

摘要

A data transmission method indicating data pending in a ZigBee network is provided, wherein the data transmission method is used to shorten a delay time for data transmission by setting a certain bit to indicate data pending in the ZigBee network to a ZigBee device, the certain bit indicating data pending to an acknowledge frame for acknowledging a data frame from the ZigBee device. The data transmission method according to the present invention includes broadcasting beacons so as to allow the ZigBee coordinator to maintain the connection of the ZigBee network; downloading a data frame from an assigned ZigBee device transmitting the data frame by receiving the beacons; and transmitting an acknowledge frame including a data pending bit indicating data pending to the assigned ZigBee device.
