ESP32 Forum

Hi,

I am designing a product which may need upgrade of my app in field.
I was thinking of FOTA where one uploads the new binary using browser on android phone or laptop as below

1) The service personnel could go to the device, connect to it using WiFI.
2) Open browser on android phone or laptop etc.
3) The device could provide a webpage using which a new binary could be uploaded.
Many WiFI routers upgrade this way.

Any help to similar project or library or example would help.

Thanks,
WI

Looks good. Any pointers about how this would integrate with encrypted flash and secure boot?

Has anyone had any luck getting lws-esp32-factory to build?

Ive tried everything and keep getting errors...its too bad because it looks like an amazing setup...
