Abstract:

A Wireless Answering Question Implement with statistics function is designed to substitute raising hands to facilitate teaching.The Answering Question Implement is based on the chip SOC-CC2530 form TI witch support IEEE 802.15.4.The article analyses the protocol for the implement,describes the process of transmission and reception,and gives the gist of hardware and software design.Experiment shows that the implement meets the need of teaching with good stability and reliability.
