I'm looking for a small, thin example of the ESP32 hosting a webserver to accept firmware update files for OTA updates. There's a handful of Arduino libraries that do exactly this (e.g. https://github.com/ayushsharma82/ElegantOTA) but I haven't come across anything clean that's just built around IDF.
https://github.com/espressif/esp-idf/tree/master/examples/system/ota ?
Here's are the two main files of interest. The OTA interface. https://github.com/mill1000/i2s-upnp-bridge/blob/main/main/ota_interface.cpp
If you are up to reading Pascal, look at this example: https://github.com/ccrause/fpc-esp-freertos/blob/master/examples/otatest/otatest.pp
I overcame my laziness and threw something together. In case anyone needs similar functionality in the future: here ya go. There's some cruft in there and things could be renamed, but this should still save you a few hours.
