Webupdate as additional feature

[22MarioZ]

First I have to say the WiFiManager is a great and easy to use. Big thanks to developer. An addition as webupdate would be relay nice. This is just my suggestion for future improvements.

PS: For webupdate I only tested code example as part of Arduino ESP32 examples.

you mean manual upload sketch from web?

I mean uploading new FW via web. In Arduino you can find the sketch under Examples -> Wemos LOLIN32 -> WebServer -> Webupdate. See pic:

This would make the WiFiManager really a powerful tool.

• cannot upload files in captive portal, file select is not allowed, show message with link or hide
• cannot upload if softreset after upload, maybe check for hard reset at least for dev, ERROR[11]: Invalid bootstrapping state, reset ESP8266 before updating
• add upload status to webpage somehow
• abort upload if error detected ?
• supress cp timeout on upload, so it doesnt keep uploading?
• add progress handler for debugging
• combine route handlers into one callback and use argument or post checking instead of mutiple functions maybe, if POST process else server upload page?
• add upload checking, do we need too check file?
• convert output to debugger if not moving to example
