Bluetooth Technology And Applications

Abstract

This thesis concerns about Bluetooth technology; the history, the name, logo and how it all started. This thesis also contains the working principle of Bluetooth and its specifications. There are also different versions of Bluetooth which will be explained in detail in chapter three of this thesis. There are different applications of Bluetooth and just like other wireless technologies, the security issues all of which will be covered in chapter four and five re-spectively.

The main objective of this project was to create a heart rate sensor which can be connected to a smart phone. This was carried out using nRF51 mbed, a compiler (mbed.org was used in this case), nRF connect software and a Samsung s9+ was used as the smart phone. The code to enable the heart rate sensor of the mbed and to make the mbed discoverable via Bluetooth was to be written, complied and with the drag and drop functionality of the mbed, dragged in to the mbed disc which was connected to a laptop. The nRF connect software helped to display the simulated heart rate reading.

This project will help point out the benefits of Bluetooth for educational purposes as well as personal and Business purposes
