Discover IoT Development with ESP32 to Create Production-Grade Smart Devices
Posted by on
The ESP32 is a low-cost, low-power SoC (System on Chip) microcontroller with integrated WiFi and dual-mode Bluetooth. It has shipped over 100 million units as of 2018 and powers many WiFi devices on the market. This book supplies end-to-end coverage of building an IoT system from the ground up to secure data communication techniques from sensors to cloud platforms that will enable you to develop production-grade IoT solutions using the ESP32 SoC.
Starting with the fundamentals of IoT combined with real-world use cases, this book will take you through every aspect of building an IoT device using the ESP32 from scratch. With every chapter, you will learn to grow your IoT applications with features like sensor communication integrating popular IoT libraries such as Little FS, LVGL, and more. In addition, the chapters describe connectivity via WiFi/BLE, security features, cloud connectivity, and real-time data visualization techniques using Grafana.
Furthermore, a complete section covers AI/ML for embedded systems. You will discover how to build and run ML applications using TInyML and ESP32-S3 to create state-of-the-art embedded products.
The book utilizes a hands-on technique to have you start building IoT solutions right from the start. An end-to-end IoT solution in the form of a Smart Home resides towards the end of the book, where you involve all the techniques learned throughout the book in real time.
espBerry - ESP32 Development Board with Dual Isolated CAN Bus HAT
The espBerry DevBoard combines the ESP32-DevKitC development board with any Raspberry Pi HAT by connecting to the onboard RPi-compatible 40-pin GPIO header.
The Dual Channel CAN Bus expansion HAT, designed for the Raspberry Pi, supports the full CAN2.0 Standard, and it features multi onboard protection circuits, high anti-interference capability, and reliable operation. As a result, it suits applications such as automotive devices or industrial automation.
The HAT is well documented, and there are multiple code samples using the C programming language under the Arduino IDE. Read more...
Under Development: Programmable CAN Bus to USB, Bluetooth, BLE, WiFi Gateway
For the longest time, I had resisted the idea of creating my version of a CAN-to-USB gateway, primarily due to the vast competition. A professional CAN/J1939 development requires a professional CAN-to-PC solution to monitor data traffic. I am pleased with the PEAK PCAN-USB device, as shown in the above image. However, not everybody is willing [...]
Selection Criteria and Requirements for a Telematics Gateway
The March 2023 issue of the CAN Newsletter, a CiA (CAN-in-Automation) online publication, posted an article on the selection criteria and requirements for a Telematics gateway. With cars evolving towards network technologies, OEMs (Original Equipment Manufacturers) require telematics solutions that boost seamless communication within and outside the vehicle. The device should be cloud-enabled, connectable to servers for real-time [...]
SAE J1939 Protocol Stack Sketch for ESP32 Using the Arduino IDE
The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Furthermore, the processor provides the means to easily [...]
NMEA 2000 / SAE J1939 Data Scanner with BLE Interface for iOS Applications
This post is a follow-up on NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications. In this new post, I also include SAE J1939, since NMEA 2000 is based on J1939. Also, in this particular case, instead of the NMEA2000-compatible 5-pin M12 connector, I used a DSUB9 as it applies to the CAN Bus [...]
NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications
Our N2K-BT gateway functions as a NMEA 2000 to Bluetooth data scanner for any host device with a Bluetooth or BLE (Bluetooth Low Energy) port, such as PCs, phones, or tablets. Therefore, it supports operating systems such as Windows, Linux, iOS, Android, and more. In addition, the wireless communication protocol employs easy-to-read and easy-to-process ASCII [...]
ESP32 Project: USB to Bluetooth Gateway
The ESP32 processor allows the integration of Wi-Fi, Bluetooth, and Bluetooth LE (BLE) for a wide range of IoT (Internet of Things) applications. Using Wi-Fi ensures connectivity within a large radius. At the same time, Bluetooth allows the user to easily detect (with low-energy beacons) a module and connect it to an Android/iOS smartphone or [...]
ESP32 Based CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway
The following is a follow-up on our post Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications. The CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway is the first product of a new series of wireless gateways for IoT (Internet of Things), ELD (Electronic Logging Devices), and other applications. At the [...]
Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications
Due to the global shortage of electronic components, we at Copperhill Technologies began rethinking our strategy regarding new developments.
