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.
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.
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.
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.
In this series of article about firmware and how to update It, I’d like to add a series of alternative methods of updating that are very useful for me.
In this article, we will learn how to add an FTP server to our device and use It to upload firmware and filesystem updates.

In this article, we will learn how to use external storage like the SD card to update firmware and filesystem.
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi connection rather than a serial port.
In this article we are going to explain OTA update via HTTPS secure connection, and with a valid self signed certificate trusted from the client.
This starting guide will talk about how it works LineaMeteoStazione, a bit more technically speaking.

OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi connection rather than a serial port. Such functionality becomes extremely useful in case of limited or no physical access to the module.
In this article we will explain the OTA update with an automatic REST request that starts the download and flash if the firmware version is not updated.
