Share a Camera Preview Using NFC and Bluetooth
The idea of this project is to allow two or more individuals to quickly join a peer-to-peer network using NFC and Bluetooth. NFC is a good choice because it reduces the number of steps users must complete to create a network. We’ll take advantage of the user-friendly NFC method to pair devices and rely on the NFC-initiated higher-bandwidth Bluetooth network to handle the heavy lifting.
Our sketch will use a recursive program to send an increasingly accurate live camera image from one Android device to another.
