Amrita Deb, Swarnabha Sinha · IOSR Journal of Computer Engineering · 2014
The project discussed here is an Android messenger application which connects using Bluetooth.The main concepts discussed here are : i) Bluetooth connection between two or more android smart phones, whereby users can chat with each other ii) Bluetooth connection between a server and an android smart phone ,whereby the user can update and synchronise his/her chat records with the server from time to time.iii) Data structures used in storing and updating the data (messages) against respective usernames.iv) State machines and finite expressions used to achieve robustness, thereby delivering error free messages.This whole project has been designed using python programming language.This app doesn't require an internet connection rather uses the in-built Bluetooth facility in a phone.Hence it comes in handy for charge-free short distance communication between individuals within a certain range (30 or 150 ft, depending on the hardware).
