Design of the Wireless Data Communication System Based on nRF905

Based on the transceiver nRF905,a type of wireless data communication system is designed,which can transfer data wirelessly such as the communication among device data(data of three or more meters in family).First,the structure,working model and saving and receiving working process of nRF905 is introduced,then,the structure of a system and the design of its hardware are given;finally the design of communication protocol is described.By providing a reasonable communication protocol,the addressing problem is settled well to assure the high reliability of communication.The system has a good effect in practice.
