In this series of article about firmware and how to update It, I’d like to add a series of an alternative methods of updating very useful for me.
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. 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.
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 how to do an automatic update from an HTTP server.
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi.
In this article we are going to explain OTA updates via Web Borwser with a custom web page.
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi.
In this article we are going to explain OTA via Web Borwser of signed firmware and HTTPS with self signed certificate.
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi. In this article we will explain how to make OTA updates via Web Browser, with and without basic authentication.
An important features that simplify the sharing of firmware (and It is used by the most productor) is to generate pre-compiled binary file with only the sketch part (or filesystem).
In this article we are going to generate filesystem binary file and we try to flash esp8266 with Espressif Download Tool.
The ESP32 has enough resources to be able to use a FAT system which is certainly more expensive in terms of resources, but which offers large dimensions and few limitations, as well as compatibility with various devices.
LittleFS was recently added and focuses on higher performance and directory support, but has a higher resource consumption and occupancy per file, although not by default for esp32 it should be remembered that it takes up less resources than FatFS.
I would like to monitor the status of my ABB Aurora inverter (formerly Power One now Fimer). So with a WeMos D1 mini I create a monitoring station with web interface, notifications and more.
Here we will explore the infrastructure of the project.
