Description

This hands-on training course provides an in-depth exploration of IoT technologies, focusing on microcontroller-based IoT solutions. Participants will gain practical experience with industry-standard communication protocols, security frameworks, and real-world IoT deployments.

The course covers:

Deploying and configuring a local open-source IoT platform.

Understanding and implementing IoT Edge-to-Cloud communication protocols (MQTT, MQTT-SN, CoAP).

Analyzing IoT security threats and applying protection measures across the IoT stack (devices, communication networks, cloud).

Configuring LwIP (with MQTT), FreeRTOS, and MbedTLS for STM32-based IoT applications.

Exploring the Amazon FreeRTOS architecture and its IoT libraries.

Hands-on lab exercises with STM32-based boards connected via Wi-Fi or Ethernet to a private cloud server.
