Bluetooth Communications App Using App Inventor

Abstract

App Inventor developed by MIT is a visual programming development environment. App Inventor allows the user to create apps for the mobile operating system Android. MIT App Inventor is an innovative programming and app creation that transforms the complex language of text-based coding into visual, drag-and-drop building blocks. In MIT App Inventor, we program using visual programming are called Initial Learning Environments (ILE). It was developed at Google Labs by a team led by MIT's Hal Abelson. Bluetooth is the communications technology. Bluetooth establishes a very low power, short range (up to 10 meters) communications link between two devices. Bluetooth uses the frequency band (2.4 Ghz). Bluetooth use forms of spread spectrum radio links that result in signals moving around within a wide band in ways that enable sharing of the spectrum by multiple devices. In present work, we are creating two separate apps for Bluetooth communications, one is a “server” app that runs on one device, and the other is a “client” app that runs on a second device. In present work the developed app is used for Bluetooth communications and implemented a simple method for sending text data back and forth between two Android devices over the Bluetooth wireless link
