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 0

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: HTTPS (SSL/TLS) and self signed certificate 0

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.
