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

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.
