Arduino-ESP32 – How to update to the latest Arduino-ESP32
- Go to https://github.com/espressif/arduino-esp32 to check for the availability of the latest version of Arduino-ESP32;
- Go to the directory where the libraries of Arduino-ESP32 are installed on your computer.
How do I send data to ESP32 over Wi-Fi?
The ESP32 server creates its own wireless network (ESP32 Soft-Access Point). So, other Wi-Fi devices can connect to that network (SSID: ESP32-Access-Point, Password: 123456789). The ESP32 client is set as a station. So, it can connect to the ESP32 server wireless network.
How does an OTA update on an ESP32 work?
OTA (Over-the-Air) update is the process of loading new firmware to the ESP32 board using a Wi-Fi connection rather than a serial communication. This functionality is extremely useful in case of no physical access to the ESP32 board. There are different ways to perform OTA updates.
Can a ESP32 be programmed using Arduino IDE?
In this tutorial, the ESP32 will be programmed using Arduino IDE. If you want to learn how to do the same using VS Code + PlatformIO, follow the next tutorial: ESP32 OTA (Over-the-Air) Updates – AsyncElegantOTA (VS Code + PlatformIO) You can install the AsyncElegantOTA library using the Arduino Library Manager.
Do you need an Arduino IDE for OTA?
One is the basic OTA method which requires an Arduino IDE and the other is a Web Updater OTA method which only requires a browser to update your program. We will look into both the methods and understand how to use them, so tune in till the end to learn everything.
How to do over the air updates for ESP32?
In this guide, you’ll learn how to do over-the-air (OTA) updates to your ESP32 boards using the AsyncElegantOTA library. This library creates a web server that allows you to upload new firmware (a new sketch) to your board without the need to make a serial connection between the ESP32 and your computer.
