Build Your Modular IoT Kit: Developer's Guide

1. General Overview Of The System

The modular IoT system comprises two integral components: a gateway and multiple nodes. The gateway consists of a Nucleo F429ZI microcontroller combined with a W5300-TOE-Shield module, establishing a connection to the router. This guide provides a clear and comprehensive explanation of the system's components, their functionalities, and their interaction.

Gateway Component:

The gateway is constructed by integrating the Nucleo F429ZI microcontroller with the W5300-TOE-Shield module. This configuration enables the gateway to connect to the router and perform two distinct roles:

  • Ethernet Server: The gateway consists of an Ethernet server, designed to accept incoming connections from nodes within the network. This server establishes a fixed address, based on the gateway's IP address. For instance, if the gateway's IP address is, the Ethernet server is located at This positioning enables efficient communication with connected nodes.
  • Ethernet Client with PubSub Integration: The gateway also consists of an Ethernet client, encapsulated within a PubSubClient. This client encapsulation facilitates the transmission of data received from nodes to an MQTT broker. Data acquired from nodes is processed by the Ethernet client and then forwarded to the MQTT broker for wider dissemination.

Node Component:

Nodes are constructed around the WizFi360-EVB-PICO module, often paired with either a sensor or an actuator. The behaviour of nodes can be divided into two categories:

  • Sensor Nodes: Nodes equipped with sensors operate as Wi-Fi clients, actively searching for the Ethernet server on the connected network. Upon locating the server, a connection is established, and sensor data is transmitted to the server. This connection is temporary and is re-established at predetermined intervals, ensuring consistent data flow.
  • Actuator Nodes: Nodes featuring actuators maintain a lifelong connection with the Ethernet server. This persistent connection enables real-time interaction with the server, facilitating immediate response to commands or instructions issued by the server.

Dashboard Integration:

The system's dashboard is linked to the MQTT broker via a JavaScript-based MQTT client. This connection permits real-time interaction with the data originating from nodes:

  • Data Publication and Subscription: Whenever new data is collected from the nodes, it's formatted as "nodeID: value" and published to a subscribed topic corresponding to the kit's unique identifier (Kit ID). This arrangement ensures that the dashboard receives the latest data updates from the MQTT broker
  • Widget Update: The dashboard features widgets designed to display specific data. Upon receiving updated data via MQTT, the relevant widget, identified by the associated node ID, is promptly updated with the new value. This mechanism enables users to visualize real-time changes in data from the connected nodes.

We have developed a sophisticated yet user-friendly dashboard that serves as a powerful visualization and control hub for our IoT nodes. This dashboard represents a dynamic canvas where multiple widgets can be seamlessly added, resized, and aligned, granting users the creative freedom to compose their own intricate IoT experience.

Constructed entirely through the utilization of HTML, CSS, and JavaScript, our dashboard exemplifies a commitment to modern web technologies. The integration of the Interact JS library facilitates a seamless drag-and-drop canvas, enabling users to arrange widgets to their preferences intuitively. Moreover, the application's state is preserved using Local Storage, ensuring that the dashboard configuration remains intact even after a page reload, providing an uninterrupted experience.

A cornerstone of the dashboard's functionality lies in its ability to establish an MQTT connection between the browser and our MQTT broker. We've harnessed the power of the MQTT js library to facilitate this connection, fostering real-time data exchange and communication between the dashboard and the IoT nodes. This two-way conduit ensures that information flows seamlessly, enabling users to interact with their nodes in real-time through the familiar web browser interface.

Sensors are like the "senses" of electronic devices. Just as our eyes see light, our skin feels touch, and our ears hear sound, sensors enable electronic devices to perceive the world around them.

Sensors or Actuators

An actuator is a device that takes a signal or command from a control system (such as a computer or a sensor) and converts it into physical action or movement. In essence, an actuator is what causes something to move, change position, or perform a specific action based on an input signal.

Deploying Modular IoT in the Low Energy Realm with BLE

In our relentless pursuit of innovation, we have extended the boundaries of the Modular IoT Kit to a BLE (Bluetooth Low Energy) variant, ushering in a new era of efficiency and longevity within the realm of low-energy IoT applications. With an emphasis on prolonging the lifespan of battery-powered nodes, while optimizing their size, our BLE variant stands as a testament to our commitment to cutting-edge solutions.

One of the cornerstones of this evolution is the strategic incorporation of BLE technology. Designed to minimize power consumption, BLE ensures that nodes equipped with smaller batteries can operate significantly longer, extending their operational lifetime and minimizing maintenance requirements. This optimization paves the way for smaller node designs, seamlessly merging energy efficiency with compact form factors.

Architecturally distinct from its predecessor, the BLE variant unveils a refined architecture to cater to its unique demands. At the heart of the gateway lies the W5300 chipset, synergistically coupled with the STM32 F429ZI microcontroller. Serially integrated with the Seeed Studio Xiao ESP32C3, this combination enables BLE connectivity to the gateway, thereby enriching the interaction possibilities. Notably, the ESP32C3 assumes the role of a multi-connect BLE server, accommodating simultaneous connections from multiple BLE clients—a pivotal enhancement in scalability.

Within this architecture, data flow is meticulously orchestrated. Data received from BLE clients is seamlessly relayed to the STM32F429ZI microcontroller through a serial port connection. Subsequently, this data is directed to the W5300 chipset, where it is encapsulated for MQTT transmission. The 16-bit bus in W5300 TOE Shield enables the real-time transfer of data between STM32 F429ZI and W5300 without any delays. Leveraging the ethernet client encapsulated with the pub-sub client, data is then efficiently transmitted to the MQTT broker—a seamless journey from BLE to MQTT.

Turning our attention to the node side, the Xiao ESP32C3 once again takes centre stage. Here, it operates in BLE client mode, effectively facilitating bidirectional data exchange with the server. This communication dynamic underscores the interoperability of our ecosystem, where the BLE-enabled nodes actively engage in data exchange with the gateway.

Undoubtedly, the smaller form factor and optimized energy consumption of the Xiao ESP32C3 emerge as pivotal features on the node side.
