On the Development of Bluetooth Low Energy Devices

摘要

This paper investigates the possibility to develop a Bluetooth Low Energy (BLE) device as part of Internet of Things chain. For this purpose, both the hardware and the software aspects are considered. Thus, the BLE software stack from Texas Instruments and the CC2541 platform were chosen. Considering the CC2541 Keyfob device which contains an accelerometer, new facilities are firstly introduced by modifying the existing embedded software. Then, a new hardware component is connected, and the necessary software components are included in order to use this new element. The two main applications that are employed to monitor the activity of the BLE devices are analyzed and a new one based on MATLAB is introduced to improve the facilities of the existing applications. Thus, using the ideas presented in this paper, new BLE devices can be developed.
