Style short distance wireless communication has two kinds: infrared IrDA (InfraRed Data Association) and radio frequency technology (Radio Frequency). Because the infrared directional strong, short distance, and can not have shelter, so it is difficult to popularize application. RF technology because of advantages of low power consumption and no direction, and by the favored. This paper introduces the current situation and development trend of wireless communication technology, and the historical background of the 2.4GHz band are discussed. Then, the hardware design and software design of the system are introduced in detail, finally, the code is given. Welding PCB plate, and the system performance test.
