Abstract
The paper generally seeks to demonstrate an in depth understanding of computer communication using Bluetooth. The working principle of this technology has to be fully understood and thus the software required to save the phone book to the computer needs to be developed and implemented and thus demonstrated on how it works. The paper clearly illustrates how reliable the Bluetooth phone book manager is in terms of creating a backup of one’s contacts. The software program is developed and then analysed in depth to understand the workability of the phone book manager which runs on any computer and is compatible with any phone. The hardware used is USB Bluetooth dongle, a cell phone and a computer.
