“Finally, the firmware now supports authenticated OTA updates, so future builds can be installed through the browser instead of connecting the board over USB.”
What does that mean?
- alexchamberlain 2mo agoOTA = over the air. ie online updates you’d expect of a more polished product
- ustad 2mo agoBut the browser is involved. Can the browser do OTA to esp32?
- cenamus 2mo agoThe browser connects to a webserver running on the ESP32. Over wifi -> over the air. OTA doesn't mean headless or automatic
- waste_monk 2mo agoI 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.
- mlrtime 2mo agoI have about 30-40 esp32 / esphome type devices running. Typically to flash or update a device, you would plug it into your usb port. esphome can also be flashed "OTA" which just means compiling your project locally, then pushing the binary over tcp/ip and giving an instruction to install it. With https://github.com/esphome/device-builder https://github.com/esphome/device-builder you can run a network of multiple esphome builders so you can update many devices at the same time "OTA" (TCP/IP).
