Changing WiFi credentials post-soldering?

[dominikheinz]

Is there a way to modify the WiFi credentials post-soldering the cam project? For example, when the connection couldn't be established, after several attempts the chip could create its own hotspot allowing to change the credentials for the new WiFi spot?

The sketch is already too long and requires a lot of resources. You could do something like that (using WiFiManager), but it's extra code that I don't plan to add it in this basic example.
