The two most common ones are by using basic OTA where the updates are made through the Arduino IDE or by using a web updater OTA where the web browser will cater to the OTA updates. To implement OTA functionality in ESP32, we can choose between various methods. By the end of this article, you will be able to add the OTA functionality in all the web servers which you previously created using the ESPAsyncWebServer library. Additionally, we will use the ESPAsyncWebServer library to create the OTA web server which is compatible with the AyncElegantOTA library. bin format before uploading them with this method. The AsyncElegantOTA library will allow the user to access a web server through which new firmware could be uploaded as well as files could also be uploaded to the ESP32вЂ™s filesystem wirelessly. One major inconvenience of using OTA is that we would have to manually add additional code for the OTA functionality for every sketch.

Thus, without any serial connection, we will perform OTA updates. Only a stable internet connection will be the requirement. With the help of the AsyncElegantOTA library, there will also be a feature to upload files onto the ESP32 SPIFFS.

Through OTA programming, the ESP32 board will wirelessly update new sketches. ESP32 OTA Updates using AsyncElegantOTA library By using OTA, we can simply update the firmware of all devices with one click from a remote server wirelessly. But the question is how you will update the new firmware to these thousands of devices that are already deployed at remote locations? Performing updates one by one by getting physical access to each device will be a wastage of time and resources. You have created a new feature as per the demand of the client. After some time, your customer asked you to add a new feature to the device. For example, you have developed a new IoT device and deployed thousands of such devices at different remote locations. Over the air or OTA is a commonly used process to update the firmware of these devices wirelessly without having physical access to devices. Therefore, it is very inconvenient to get physical access to these devices to perform applications updates. In embedded systems and especially in IoT applications, the devices are usually deployed at remote locations.

Uploading a new sketch wirelessly from Arduino IDE is intended for the following typical scenarios: This type ofВ functionality is extremely useful in case of no physical access to the ESP module. OTA (Over the Air) update is the process of loading a new firmware to ESP8266 module using WiFi connection rather than a serial communication.
