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.
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.
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
For me, It’s very important the network connection and network limitation on STM32F1 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
We have already looked at how to add a wiring connection to an STM32, but sometimes the only solution can be a Wireless or WiFi connection, and in this article we are going to see how to manage a complete WiFi solution.
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.
