Abstract

Bluetooth Low Energy (BLE) technology, operating within the widely used 2.4 GHz ISM band, stands as a cornerstone in modern wireless communication frameworks alongside its classic Bluetooth counterpart. This paper explore the foundational aspects of BLE, excluding niche components, to explore its core functionalities and pivotal role in diverse connectivity needs. BLE's specialization in catering to low-power devices ensures optimal energy utilization, making it indispensable in IoT applications where energy efficiency is paramount. Its versatility finds applications across consumer electronics, industrial automation, and healthcare, ensuring reliability and efficiency in safety-critical systems and enhancing user convenience through remote control capabilities. However, the wireless nature of BLE interfaces exposes them to cybersecurity threats, necessitating robust security measures for mitigating risks such as sniffing, DoS attacks, and message injection. Continuous research and development efforts are essential to stay ahead of emerging threats and safeguard BLE-enabled systems and data.
