Over-the-Air (OTA) Programming on ESP32 – Basic OTA using Arduino IDE
OTA stands for Over The Air. It allows uploading a new program to ESP32 using Wi-Fi instead of connecting the ESP32 to a computer via USB to do the update. It is extremely useful in situations where you don't have physical access to the module. This feature can be used to reprogram the devices that are fixed on a roof or any other place where connecting cable is difficult.
