Design and Implementation of a Wireless Bulletin Board

ABSTRACT: Bluetooth is an important mean for wireless communication between multiple devic-es. Bluetooth is intended to support an open-ended list of wireless applications, in-cluding data, audio, graphics, and even video transmission between different devices. Therefore demand on Bluetooth will be high since most mobile devices nowadays are Bluetooth enabled. Besides Bluetooth enabled information provision system can be a solution to access information database server and can handle user’s data re-quest. This thesis is developed to enable information provision system for data trans-fer between the laptop and LED screen. The LED screen is used to show the data that the user wants to display in a fixed or motional manner. The system is designed in such a way that the KC Bluetooth mod-ule at the screen side can only receive data from one specific sender. The operation of transferring data depends on the protocol used in finding the specif-ic device and making the contact between the transmitter and the receiver. The fun-damental protocol used in this work is the Radio Frequency Communication (RFCOMM). This protocol is based on a serial communication between the two Bluetooth devices. The software part of the system is concerned with programming the Bluetooth with KC wireless in addition to another user-interface program that is designed for sending messages to be displayed on the LED screen.
