Description

UPDATE JUNE 2022:

ESPIDF BLE Code Compatibility Version Update

Hello learners!

Welcome to MAKERDEMY's “Introduction to BLE” course.

This is a beginner level course that will teach all there is to know about BLE and BLE Mesh. We will be using the most popular IoT board called the ESP32 to explore the BLE features, implementations and projects. This course is one stop destination for beginners to understand BLE in-depth and implement projects.

This course will strengthen your knowledge on the fundamental concepts pertaining to BLE and BLE Mesh and will give you hands-on experience in implementing end-to-end projects with the ESP32. You will be very confident with the BLE concepts, architecture, features, how to implement them and the security process. You will become confident to integrate BLE and MESH features into your own projects using ESP IDF and Visual Studio Code. Finally, you will implement a full fledged BLE Mesh enabled Capstone project that combines the learnings and features learned throughout the course

If you complete all sections in the course, and the course assignments, you will confidently be able to develop and work on implementing your own BLE solutions.

Throughout the course, we have provided a curated collection of original resources. These resources include links to documents for in-depth learning, links, videos, and more. At MAKERDEMY, we have a dedicated instructor team who will promptly answer any of your course-related queries.

So, what are you waiting for?! Come, join me in this course. I’m looking forward to being your instructor and to give you an introduction into the world of Bluetooth Low Energy.

Who this course is for:

Any developer or engineer who wants to get hands-on experience with Bluetooth Low Energy and BLE mesh and implement Projects based on them
Any developer or engineer, who wants to upgrade their existing project with BLE Integration
Anyone who is curious about BLE and want to learn about all its features and concepts in depth and also implement projects along the way
