How to Perform the OTA Upload to an ESP32 Board Using Arduino Cloud

Programming a device is always tedious work. You need to have the device at hand and connect a USB cable. This is acceptable for the first time you program the device, but it is really annoying when your device is already installed in a place with difficult accessibility. In those situations, you either have to remove the device from its place or bring your laptop as close as possible to its location.

That’s where over-the-air (OTA) is a game-changer. This feature enables you to upload programs wirelessly to your boards. This way, as soon as you have a compatible board connected to a WiFi network and configured to work with OTA, you won’t need to physically connect the board to the computer in order to upload new sketches to it. Instead, everything will work over-the-air.
