Description
The Internet of Things (IoT) allows us to put small devices around our environment to measure and control. The Raspberry PI Pico-W is an excellent platform for developing such IoT devices, connecting over WIFI and MQTT protocol.
In this course, we explore how to code C++ for a Pico-WÂ IoT device using the FreeRTOS coreMQTT-Agent library version v1.1.0. 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
Simple circuits to turn on and off an external LED using a local switch connected to the Pico-W are used to test the concepts.
The course assumes knowledge of C++. Though each example walks through the functionality, the course will not talk about the syntax of C++. FreeRTOS Kernel is used to support concurrent tasks for managing the MQTT protocol and an understanding of FreeRTOS Kernel is assumed. I have another course on FreeRTOS Kernel for the Raspberry PI Pico to cover this.
The course assumes you can compile and deploy C++ code to the Pico using the Raspberry PI Pico SDK. My other course â€œIntroduction to C Development Environment for Raspberry PICOâ€ teaches these skills.
Test scrips to interact with the device are written in Python. Some basic Python knowledge would be helpful.
Full captions are provided for the course and are not auto-generated.

25+ years experience of IT and Data experience across academia and commercial sector. I have worked on embedded systems, global enterprise systems, data warehouses and data lake.In my day job I lead Data and IT departments' architecture functions. I work with the business to align IT and Data Strategy with the Business Strategy. I work to plan out roadmaps of change to address the business challenges and enable IT and Data initiatives to be treated as an investment for return.In my off hours, I work as a hobby developer working on embedded IoT technologies. Some of my projects have included smart clocks, a clock that looks like a slot machine, pan and tilt security cameras, and hexapod robots. I primarily develop around the Raspberry PI and Raspberry PICO (RP2040) hardware devices with cloud services from AWS. I develop in a number of languages include C, C++. Java, Python, and Node.Dr Jon EA Ltd - UK Registered Company 14359330
