Understanding Bluetooth Low Energy (BLE) - Theoretical Overview

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 low-power 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.

Very Nice n informative video

[@edgarwcl]

Right, honestly, I am a hardware engineer and also would like to understand the deep therories in every functional diagram a long time. This video really inspir me a lot. thank you! I also also pricking up the Nordic nRF52840 :)

[@sebastianmunoz5886]

I love when youtube give me this hiddens gems. Thanks for sharing

[@wsniot]

Thx for the nice feedback.

[@roysikandarali6167]

that helps full plus can you please make series related to gatt protocol and its implementation with custom characteristics ?

[@patil29066]

It's really helpful! Can you please make videos related to MCUBoot on nRF Board?

Which one provides better range, Bluetooth LE or Thread? Also may be long battery life? Or they are the same?

[@wsniot]

The range depends largely on the frequency used and the transceiver strength. Thus, the range of Bluetooth and Thread is quite similar. Detailed information on the range and its influencing factors are described in my book "WSN & IoT". Both BLE and Thread are designed to be able to consume little power. But it all depends very much on the individual application and the traffic generated with it. A lot of data traffic also means a significantly higher power consumption. Which is why I strongly assume that the BLE Mesh consumes more power than the Thread, since the network is flooded with messages to reach a destination.

nice video.

[@wsniot]

Thx for the positive feedback.

Only discussed the host layer ignoring the controller layer😢
