+You can perform a native firmware OTA upgrade by calling the URL /setup . There is a section called "Native OTA" where you can provide two urls to the new images: One for the actual firmware image (normally named esp32-javascript.bin in your build directory) and the other for the JS modules image (normally named modules.bin in your build directory).
