OTA = over the air. ie online updates you’d expect of a more polished product

But the browser is involved. Can the browser do OTA to esp32?

  • The browser connects to a webserver running on the ESP32. Over wifi -> over the air. OTA doesn't mean headless or automatic

  • I believe the ESP32 runs a small web server that supports WebSerial (?), if you can reach it over WiFi or somesuch, you should be able to upload the new firmware blob that way.
