What you'll learn

• Set up and configure AWS IoT Core for secure device-to-cloud communication
• Connect STM32 microcontrollers to the internet using ESP32 Wi-Fi module with AT commands
• Publish sensor data and subscribe to commands over MQTT
• Implement secure Over-the-Air (OTA) firmware updates using AWS IoT Jobs and Amazon S3
• Integrate IoT devices with real-world business logic (e.g., payment gateway events)
• Build end-to-end IoT applications with real hardware and cloud workflows

Description

Are you ready to take your STM32 and IoT skills to the next level by building real cloud connected devices on AWS?

This is a brand new course that is practice first, project driven, and step by step. You will not just learn concepts. You will build along and see your STM32 devices come alive with real AWS IoT Core integration..

In this hands on, project driven course, you will learn how to connect your STM32 microcontrollers to the AWS IoT Cloud and build real world IoT applications that are secure, reliable, and scalable.

Connect STM32 to AWS IoT Core using ESP32 Wi Fi bridge, publish and control devices with MQTT, deliver secure OTA firmware updates, and integrate Razorpay payment events in hands on projects

This is not a theory heavy course. It is all about building step by step, where you will write code, configure cloud services, and see your embedded device interact with AWS in real time.

By the end, you will have the skills to implement IoT systems that go beyond simple sensor readings, integrating with advanced features such as firmware updates over the air and even cloud driven business logic with payment gateways.

What you will learn?

How to set up AWS IoT Core for secure device-to-cloud communication

Connecting STM32 with ESP32 as a Wi-Fi bridge using AT commands

Publishing sensor data and receiving commands over MQTT

Implementing secure Over-the-Air firmware updates using AWS IoT Jobs

Managing cloud-to-device messaging and real-time responses

Integrating IoT with real-world business systems (Razorpay Payment Gateway)

Building end-to-end IoT workflows from device → cloud → device

Hardware Requirements

Note: If you already have a microcontroller development board, we recommend continuing with it. This course is designed with such thoroughness that the concepts and steps can be applied to most development boards though some minor adjustments may be needed. But, if you prefer to use the exact same board as the instructor for a smoother experience, you can check out the recommended hardware

Any STM32 Nucleo board with Fastbit IOT connect shield (Recommended)

or

Any STM32 development board + ESP32 module for Wi-Fi

Projects you build

IoT Foundation Project – Connect STM32 to AWS, publish sensor data, and subscribe to commands using MQTT

OTA Firmware Updates – Deliver new firmware securely from AWS S3 and update in the devices automatically.

IoT + Payment Gateway – React to real-time Razorpay payment confirmations on your STM32 device with instant feedback on OLED display.
