In the summer of 2025, when the “Internet of Everything” is no longer just a concept but has permeated every corner of industry, home, and healthcare, a real question faces countless developers: how to efficiently build a stable and scalable IoT platform? Is the choice of protocols too complex? Are practical case studies hard to find? Is there no clear starting point for beginners? Perhaps this newly released “IoT System Development (2nd Edition)” can serve as your “development compass.”
Why do IoT developers often find themselves in “trouble”?
In the IoT development community, such complaints are common:
“I’ve read a bunch of protocol documents, but I still can’t figure out the differences between MQTT 3.1.1 and 5.0.”
“I want to set up an IoT platform, from device access to data processing, but I don’t know where to start.”
“The code examples I found online are either too old or lack comments, and they just don’t work.”
The core of these pain points lies in the lack of a “development manual” that explains both principles and practical applications, keeping pace with technological iterations. The emergence of “IoT System Development (2nd Edition)” precisely fills this gap.
From protocols to platforms: this book is “detailed enough”
Flipping through the table of contents, the structure of the entire book, with 14 chapters, resembles a clear “development map”:
Chapters 1-2 are the “foundation”: from basic IoT concepts to commonly used protocols (CoAP, HTTP, MQTT, etc.), helping you establish a foundational understanding;
Chapters 3-6 are the “core bridge”: nearly 200 pages dissecting the MQTT protocol—from the classic features of 3.1.1 to the significant upgrades of 5.0 (such as property extensions and request-response patterns), with each section accompanied by example code and line-by-line comments;
Chapters 7-14 are the “practical battlefield”: using open-source components (like EMQX, InfluxDB, Grafana) to guide you step-by-step in building an IoT platform from scratch, covering the entire process from device access to data storage and visual monitoring.
“Practicality is not an embellishment, but the soul that runs through the entire book.” The code in the book is not just “filler” snippets, but “reusable modules” validated by the author team in enterprise projects. For example, when explaining the “shared subscription” feature of MQTT 5.0, not only is the server-side (EMQX) configuration code provided, but it also details how to adjust parameters based on business scenarios to avoid the awkwardness of “code running but not being useful.”
Why is this said to be a “condensation of enterprise-level experience”?
Flipping to the front page, the author Fu Qiang’s resume is enough to reassure readers: with 15 years of experience in IoT, from Trend Micro and Nokia to founding his own IoT company, he has led several large projects including industrial equipment monitoring and smart city sensor networks; the other author, Fu Jingtao, is a “practical professor” with nearly 30 years of experience in academia, who understands both theoretical systems and the learning pain points of students/developers.
This combination of “enterprise CTO + university professor” makes the content in the book closely aligned with industrial needs (such as how to handle performance bottlenecks with high-concurrency device access) while also adhering to learning logic (for example, using a four-step structure of “starting from the problem → principle explanation → code implementation → scenario validation” to avoid “knowledge fragmentation”).
For example, in the third part “Building the IoT Platform,” the author does not just throw code at the reader but first guides them to analyze “why choose EMQX as the MQTT broker” (high concurrency, good open-source ecosystem), then breaks down “how to configure different QoS levels based on device types (low-power sensors vs. high-speed industrial devices),” and finally provides a complete Docker deployment script—each step answers “why do it this way” rather than just “type the code.”
“Learning that can be applied is real practice.” This is a repeatedly emphasized concept in the book. Among the readers of the first edition, there are fresh graduates who completed their graduation projects using the methods in the book, as well as developers from small and medium enterprises who optimized the stability of their existing platforms based on the architecture in the book—these real feedbacks have been transformed into content that is more aligned with current technological trends in the second edition (such as adapting to the new features of EMQX 5.0).
From “bestseller” to “classic upgrade”: three compelling reasons to buy the 2nd edition
If you are a beginner in IoT, it is a “0-based friendly guide”: from protocol concepts to code debugging, using “conversational explanations” instead of rigid technical documents;
If you are an experienced developer, it is a “pitfall avoidance manual”: the author has written down the pitfalls encountered over 15 years (such as MQTT message duplication and QoS level misuse) as “cautions” to help you avoid inefficient trial and error;
If you are a university teacher/ student, it is a “teaching/graduation project tool”: the accompanying code can be directly used for lab classes, and the platform building cases can support complete project practices.
More importantly, the 2nd edition keeps pace with technological iterations—when the industry transitions from “Internet of Everything” to “Intelligent Internet of Everything,” the features of MQTT 5.0 such as “property extensions” and “request-response” are key to supporting flexible interactions among smart devices. The book dedicates nearly 50 pages to comparing the differences between 3.1.1 and 5.0, combined with the new configurations of EMQX 5.0, allowing readers to “learn and apply it in new projects right away.”
Your IoT development needs a “reliable partner”
In today’s world of “fragmented technical documentation,” a book that can condense principles, practical experience, and pitfall avoidance into a system is more valuable than any “XX days quick start” tutorial. “IoT System Development (2nd Edition)” is not a theoretical book built on “air castles” but a “development manual” written by the authors based on 15 years of enterprise practical experience and 30 years of teaching insights—opening it, you gain not just a book but a roadmap from “understanding principles” to “being able to apply them.”
If you also want to break free from the cycle of “checking documents – testing code – hitting pitfalls” and truly master the core capabilities of IoT platform development, this book deserves a place on your desk. Click the link below to make it your first “reliable partner” in IoT development.
