I am delighted to announce the launch of my new Raspberry PI Pico-W course on build IoT devices. To celebrate the launch and this festive time of the year I’m giving you a voucher for the course. But wait not just the one course, vouchers for some other courses too! All for 5 days only!

In this course, we explore how to code C++ for a Pico-W IoT device using the FreeRTOS coreMQTT-Agent library version v1.2.0. We take the approach of building an IoT framework for all the devices we want to build. With the ability to connect, publish and subscribe to messages. To operate we also need an MQTT broker and the course talks through the use of Eclipse Mosquitto as a locally installed broker on a Raspberry PI, or using Flespi as a cloud-hosted broker.

The course covers:

• Establishing WIFI connectivity in station mode to an access point or router
• Building TCPIP socket transport for MQTT protocol
• Publishing messages
• Subscribing and taking action on messages

FreeRTOS Kernel is used to support concurrent tasks for managing the MQTT protocol and an understanding of FreeRTOS Kernel is assumed. As covered in my FreeRTOS on Raspberry PI Pico course.

We use basic circuits on the course with the Pico-W controlling a LED and interrupt reading from a switch. Interfacing these simple electronics and coding for them is covered in the Raspberry PI Pico Micro Projects (C++) course.

I wish you and your families to have a great festive holiday season.

Best Wishes
