Hands-On MQTT over 4G LTE: Building Reliable IoT Data Networks

Complete Source Code Included

10+ hours of training content

Developing Real-Time IoT Communication with MQTT over a Resilient 4G LTE Protocol

Navigating the Intricacies of the Controller Area Network(CAN)

Hey, I’m going to make this real simple for you.

If you’re in the world of IoT, you already know how important reliable, real-time communication is.

And if you’re not using MQTT over 4G LTE, you’re missing out on one of the most powerful ways to connect devices anywhere, without breaking the bank on bandwidth or dealing with frustrating connectivity issues.

Here’s Why You Should Care:

In this course, I’m going to show you how to implement MQTT firmware(the go-to protocol for IoT) and combine it with the speed and reliability of 4G LTE to build IoT networks that just work—no matter how remote your devices are.

Here’s what you’ll get:

Step-by-step lessons on developing 4G LTE communication drivers for your IoT devices using SIM7600 modules.
Develop MQTT firmware for real-time data transmission so your systems stay fast and efficient—even with low bandwidth.
Proven methods for troubleshooting and optimizing your networks so that even if your connection drops, your system bounces back without missing a beat.
Hands-on, real-world applications—because let’s be honest, you need more than theory to make your IoT systems rock solid.

You’ll learn how to handle real-time data transmission across long distances, with the confidence that your network can handle anything you throw at it.

By the end of this course, you’ll have the skills and know-how to build robust, reliable IoT systems that can communicate from anywhere using MQTT over 4GLTE—without the headaches.

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 100,000 students in embedded

firmware development online till date

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

If you have taken any of our 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
