Hands-On Internet of Things with MQTT: Build connected IoT devices with Arduino and MQ Telemetry Transport (MQTT) Kindle Edition

There is a lot of code in the book. By chapter 4 you’ll find out it’s already outdated. Would not buy until it’s updated.

I got a copy of this book to review and while it's OK for the beginner setting up SSL for MQTT is a must for any serious IoT book. How many IoT devices have been hacked as a result of poor security (think security cameras, etc.). I even provide how to configure this with a sample project on my github site.

Need book not kindle

I bought this book hoping to get a gentle introduction into the world of MQTT with the Arduino platform and wasn't disappointed.What I really like about this book is that some of its chapters serve as a reference on key topics (which I might revisit at a later point) while others are hands-on tutorials to build entertaining projects (e.g. a pet feeder that can be controlled via smartphone).To be honest the projects are not that special (quite simple), but they were easy to follow. I definitely prefer simple (but limited) example projects over too complicated ones that mix up a lot of different technologies, but don't explain what is going on.Another thing that I liked is the MQTT platform being used (Shiftr). This makes it super easy to understand how the MQTT messages are sent around.Would I recommend this book? Definitely!

Die Themen sind gut erklärt (auch für Leute mit wenig Arduino-Erfahrung wie mich). Das Buch reißt einiges an Themen an, etwas knapp teilweise, aber oft werden weiterführende Links zu Youtube oder Artikel zum Weiterstöbern geboten.Es wird recht wenig an Vorwissen vorausgesetzt und man kann dem Inhalt gut folgen. Für Arduino-Profis könnte es etwas langatmig sein, die Zielgruppe sind hier wohl eher Anfänger und Fortgeschrittene.Mit MQTT lässt sich echt eine Menge machen. Hätte nicht gedacht, dass es so einfach ist Nachrichten zwischen mehreren Arduinos, dem Smartphone und Computer hin und her zu schicken.
