文摘

Visible light communication (VLC), which uses visible light to achieve wireless communication just as its name implies, transmits information mainly through the high-speed light flashing of LED or fluorescent lamp. And it has many advantages, such as high security, high energy efficiency, and long life expectancy. In recent years, the application of smart devices based on the Android system is becoming more and more abundant. If the VLC is combined with smart devices based on Android system, we will have a wide range of application scenarios in the future. In this paper, by using LED lamps as the transmission side, two methods of different Android mechanisms to make the flicker in different data rate are presented. By optimizing the code framework, using new function in the hardware driver layer, the operating efficiency can be increased greatly, and the maximum data rate of 5000 bps on the Android development board is achieved. In the meantime, due to the LED’s features and experiments’ result, we give two flowcharts of application scenarios: the mobile payment and ships communication.
