In this video, we offer a comprehensive and factual explanation of Bluetooth Low Energy (BLE), shedding light on its core principles and diverse applications. We will differentiate BLE from classic Bluetooth, emphasizing its primary function in facilitating lowpower communication between devices. As we delve deeper, we'll explore the architecture of the BLE Stack, with a particular focus on essential components such as GATT, GAP, and ATT, while outlining the distinct roles of peripheral and central devices.
