MQ Telemetry Transport (MQTT) From Ground Up™

Master MQTT, the Protocol for the Internet of Things (IoT) : STM32, Cloud Dashboard, Python, Mosquitto

14+ hours | Complete Source Code Included

Have you ever wondered what MQTT is?

Have you ever wondered why MQTT is so relevant to IoT development?

In fact, what is a broker, what is topic, what is a message, what is the Quality of Service?

Imagine how exciting it will be to understand all the various component of MQTT and develop your own IoT solutions using the MQTT protocol.

Welcome to...

MQ Telemetry Transport (MQTT) From Ground Up™

This course teaches you how to develop complete IoT solutions using MQTT, the protocol for the Internet of Things(IoT).

MQTT is a lightweight subscriber/publisher binary protocol designed for machine to machine (M2M) communication with minimal packet overhead.

This course uses only the STM32 microcontroller without any specialized wireless radio. We use the UART peripheral as part of our transport layer to communicate between our firmware and MQTT clients which we shall develop from scratch in Python.

The goal of this course is to teach you all about the MQTT protocol, it's architecture and then go ahead to develop realworld case studies using the MQTT protocol.

So with that understood, let me tell you…

Exactly What You’re Getting

This course can be divided into 4 major sections.

First Section

In the first section we learn about the core cocncepts of the MQTT protocol and its unique architectural features.

This section is entirely theoretical. It is in this section that we get to understand why MQTT is needed and how it is different from HTTP.

Second Section

The second section provides practical python essential training for embedded developers.

This section is for developers who are not familiar with the python programming language and those who want to brush up on their python development skills.

This is required because we shall be developing our MQTT clients in python.

Third Section

In the third section we will write all the drivers required to enable communication between our firmware and our python applications. We shall develop drivers in python to send and receive data to and from our firmware as well as develop firmrware drivers to commnunicate with our python application.

In this same section we shall learn how to develop MQTT clients, setup a local MQTT broker and also learn how to publish mesaages to the broker as well subscribe to messages on the brok

Last Section

In the final section we shall apply all that we have learnt to develop a Farm Management System based on the MQTT protocol.

Over here we shall understand how to approach such a complex project, decide on the best design pattern and then go ahead to develop two farm management systems, one that communcates with only local broker and another one that communicates with both a local broker and a cloud broker.

We shall also develop a beautiful looking cloud based modern dashboard to help us to properly visualize the data from our firmware.

Closing Remarks

A little about me : Israel Ninsaw Gbati

Some of you may have taken some of my embedded systems courses from other online platforms.

This is my private channel.

I have been writing embedded firmware for years, I have built embedded devices like consumer products and robotic arms.

Till date I have

trained over 75,000 students in embedded

firmware development online till date

...including third year undergraduate university students in-person.

If you have taken any of my courses before you will know I start from the absolute basics, I do not assume that the student has any prior knowledge of the topic under discussion. You will also know that by the end of the course you understand the functions of every register used in developing the particular firmware or driver.

This method is the same for all of my published embedded systems courses.

Our courses have been reviewed by 1000+ students
