Abstract
Recently, IoT devices are widely used in smart factories and the like. These IoT devices require
a network and typically use Wi-Fi. However, devices with Wi-Fi must be certified, and certification costs are high. So businesses are replacing authentication via USB, with the exception of Wi-Fi. However, using this method causes difficulties in setting up Wi-Fi. To solve this problem, we implemented a method of delivering configuration information using a low-cost microphone and speaker. In mobile application, input serial number of IoT device, select configuration information, convert it into binary data, and transmit it by frequency shift keying (FSK) method. At the receiving end, Arduino accepts and interprets the frequency through the microphone, demodulates it into binary data, converts it into serial number and configuration information, and
checks it through the LCD.
