@OBDave, I have done what your looking for. My device acts as a AP. Clients connects to ESP32, opens browser, and then chooses what file to upload. It then flashes itself and reboots. I am not aw work now, but will show code when I get back.

Friends, hello!
I've been looking for something exactly the same way you have described.
I need a bootloader with an AP network, in which the user can just access the ESP AP, choose a bin file from his computer and upload the code.
The bootloader needs to be preserved for further updates. I mean, I understand that on each restart, ESP will create a AP network for some seconds, if the user don't access the network and type the IP address on browser, the ESP will automaticaly run the last main code updated, but if the user access the AP network, choose the file and update it, ESP will automaticaly reset after the file upload and restart with another code writen in its flash memory.
Could you please share the source of such amazing code, please?
Thanks!
