I'm developing an iot project, to bring the product to market. I need to make OTA updates available. What's the best approach for this? I have found an OTA Library. But it doesn't explain how to manage it in a safe way from an external update server.

I'm making a paper where I research the best way or the apropriate way to make product with the ESP32 chip that can go to market. Knowing that the Arduino code that you upload to the ESP32 is lighter than micropython. Is it the best for consumer based product? Why would it? Why wouldn't?
