Objectives

Introduce the IoT ecosystem
Learn how to deploy an local open source IoT Platform
Describe the most used IoT Edge to Cloud Protocols (MQTT, MQTT-SN and CoAP)
Explore particularly heinous IoT focused attacks and security provisions at each level of stack (physical devices, communication systems and networks)

Basic knowledge of embedded processors
Basic knowledge of multi-task scheduling
Basic Concepts of Cryptography
Basic knowledge of STM32 microcontrollers
FreeRTOS (one of the following):

RT3 – FreeRTOS Real-Time Programming

Course Environment

Theoretical course

PDF course material (in English) supplemented by a printed version for face-to-face courses.
Online courses are dispensed using the Teams video-conferencing system.
The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.

Practical activities

Practical activities represent from 40% to 50% of course duration.
Code examples, exercises and solutions
For remote trainings:

One Online Linux PC per trainee for the practical activities.
The trainer has access to trainees' Online PCs for technical and pedagogical assistance.
QEMU Emulated board or physical board connected to the online PC (depending on the course).
Some Labs may be completed between sessions and are checked by the trainer on the next session.

For face-to-face trainings:

One PC (Linux ou Windows) for the practical activities with, if appropriate, a target board.
One PC for two trainees when there are more than 6 trainees.

For onsite trainings:

An installation and test manual is provided to allow preinstallation of the needed software.
The trainer come with target boards if needed during the practical activities (and bring them back at the end of the course).

Downloadable preconfigured virtual machine for post-course practical activities
At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed

Target Audience

Any embedded systems engineer or technician with the above prerequisites.

Evaluation modalities

The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
Trainee progress is assessed in two different ways, depending on the course:

For courses lending themselves to practical exercises, the results of the exercises are checked by the trainer while, if necessary, helping trainees to carry them out by providing additional details.
Quizzes are offered at the end of sections that do not include practical exercises to verifythat the trainees have assimilated the points presented

At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.

In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
