ESP32 self OTA update firmware from a server with version check – 2
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.
BNO055 for esp32, esp8266, and Arduino: Gyroscope High Rate and Any Motion Interrupt – 6
This latest article in the series explores how to use the BNO055 sensor with ESP32, ESP8266, and Arduino to achieve gyroscope high rate and any motion interrupt. The BNO055 sensor combines an accelerometer, magnetometer, and gyroscope in one module, making it ideal for accurate orientation tracking.
ESP32 self OTA update firmware from server – 1
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.
ESP32 OTA update with Web Browser: custom web interface – 3
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.
ESP32 OTA update with Web Browser: upload in HTTPS (SSL/TLS) with self-signed certificate – 2
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.
ESP32 OTA update with Web Browser: firmware, filesystem and authentication – 1
In this article series, we will explore how to perform an OTA update on the ESP32 microcontroller using a web browser with and without basic authentication. We will cover firmware update, filesystem update, and authentication, providing practical examples and code snippets along the way.
ESP32 OTA update with Arduino IDE: filesystem, firmware, and password
One of the most important features of the ESP32 is the ability to perform over-the-air (OTA) updates, which allows developers to remotely update the firmware of the device without the need for physical access.
In this article, we will explore how to perform an OTA update on an ESP32 using the Arduino IDE. We will cover the entire process, including updating the filesystem and firmware, as well as securing the OTA update with a password.
ESP32: flash compiled firmware and filesystem (.bin) with GUI tools – 2
The ESP32 boasts a crucial capability that streamlines the sharing of firmware, which most manufacturers widely utilize. This capability involves creating a pre-compiled binary file containing the sketch portion (or filesystem). In this article, we will create a binary file for the filesystem and proceed to flash the ESP32 using the Espressif Download Tool.
ESP32: flash compiled firmware (.bin) – 1
An essential feature of ESP32 core that simplifies the sharing of firmware (and most manufacturers use it) is to generate a pre-compiled binary file with only the sketch part (or filesystem).
In this article we will generate a firmware binary from the command line.
