Firmware is a specific class of computer software that provides the low-level control for a device’s specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device’s complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems, home and personal-use appliances, computers, and computer peripherals.
This article will guide you through the methodology of remotely programming an Arduino UNO using ESP8266 modules, specifically focusing on NodeMCU and ESP01, utilizing the ESP-Link firmware. This firmware acts as a bridge, enabling WiFi and serial communication, thereby changing the way we interact with microcontroller boards like the Arduino UNO through ESP8266.
Unlock the potential of wireless Arduino UNO programming with DT-06 and ESP-Link Firmware. Our guide explores the seamless integration of WiFi and serial communication, transcending the DT-06’s original firmware limitations, and upgrading remote device management in the IoT domain
We have already addressed the topic of remote wireless programming via Bluetooth of an Arduino UNO in our previous article titled “Arduino Remote/wireless Programming” however, thanks to the feedback and questions from our readers, we have decided to delve even deeper into this subject, exploring the possibilities that WiFi connectivity offers.
Welcome to the final article in our ESP32 firmware and OTA update management series. Today, we’ll explore using an FTP client to update the firmware and filesystem on an ESP32 device. Join us as we delve into this last technique, equipping you with valuable insights for managing updates on your ESP32 projects.
In this article, we explore a non-standard but effective method for updating ESP32 firmware and filesystem using an SD card. We’ll discuss the advantages, disadvantages, and provide a step-by-step guide for implementing this technique, building on knowledge from previous articles in our firmware management series.
We are going to continue exploring OTA updates. In this article, we delve into secure self OTA updates for ESP32 devices using HTTPS (SSL/TLS) with trusted self-signed certificates. Learn how to generate certificates, set up the ESP32, and configure the update server for enhanced security and efficiency in your IoT projects.
In this article, we’ll explore an efficient method for implementing self Over-the-Air (OTA) firmware updates for the ESP32 microcontroller, complete with version checking. This approach enables IoT devices to automatically download and install the latest updates from a server, ensuring a resilient and adaptable IoT ecosystem without requiring manual intervention.
This article discusses how the ESP32 can perform self-OTA updates of its firmware from a server, allowing you to remotely update the firmware of an ESP32-based device without having to physically access the device. To do this, you need to set up a server that hosts the new firmware image and add OTA support to your ESP32 firmware. By implementing self-OTA updates, you can ensure your devices are running the latest firmware without having to physically access them.
This tutorial explores how to implement OTA updates on an ESP32 using a web browser as a custom interface. We will create a custom web interface using HTML and JavaScript to upload firmware files to the ESP32, and then use the ESP32’s OTA update feature to install the new firmware. By the end of this tutorial, you should have a solid understanding of how to use OTA updates to keep your ESP32 devices up-to-date with the latest firmware.
In this article, we will explore how to perform OTA updates on the ESP32 using a web browser and HTTPS protocol with a self-signed certificate. HTTPS provides a secure way to transfer data over the internet and is essential for any OTA update process that involves sensitive information. A self-signed certificate can be used to provide encryption and authentication without the need for a third-party certificate authority, making it a cost-effective solution for small-scale projects. By the end of this article, you will have a working OTA update process for your ESP32 project that uses HTTPS protocol and a self-signed certificate.
