The purpose of this project was to configure a smart phone to a given Wi-Fi network using NFC and QR Code. In this thesis, the methodology of both technologies, NFC and QR Codes, is discussed.
Near Field Communication (NFC) is a recent technology with many applications. Most of recently released smart phones have a built in NFC reader/writer chip, allowing them to write and read an NFC tag. In this project Adafruit’s PN532 NFC/RFID controller breakout board and Mbed LPC1768 microcontroller were used to communicate with an NFC-capable smart phone in Peer-to-Peer mode.
QR Codes are 2-dimentional barcodes developed for holding more information than basic barcodes. In this thesis Wi-Fi network information is encoded to QR Code and displayed on an E-paper display. A library developed by Fukuchi Kentaro was used for encoding the Wi-Fi data. Later the displayed QR Code was scanned with a Samsung Galaxy s4 phone to establish a Wi-Fi connection.
For testing both the NFC PN532 board and QR Code a specific application was needed to be installed on the phone. Barcode Scanner from ZXing Team was used for the QR Code and AppNearMe application was used for the PN532 Breakout Board. Easy and fast Wi-Fi network configuration was achieved through QR Codes.
