I think so. However since they are copyrighted to Espressif I think adding this to the NOTICE is needed. I just pushed this change.

Ok, we can document that elsewhere then. There's no documentation for using the wapi tool nor how to setup WPA2 AFAIK so it would be good to have it somewhere.

BTW, I just tried to flash the wapi config to my devkitc and it does now work unless I disable the "save wifi params" option. Can someone explain if this is a bug or how is it supposed to be used? This probably needs to be mentioned in the docs

Did you have enable SPIFlash to have the file system mounted?

Yes, I'm using master. I just erased flash and reflashed all binaries. It appears to work now after a reset.
I did flash bootloader/partition before this test today so those were latest ones. Maybe we should add erase_flash to the
bootloader/partition flashing? Otherwise, maybe I can add an instruction to docs to do this erase before flashing them.

The wapi config has all what's necessary to run the example. I did notice however some issues in devkitc in the past with saving the parameters (and thus SPI Flash). Other boards however never had any problem. Could be that the partition is too large for a 2MB flash.
That said, thanks @v01d for starting this!!! I had this in the back of my head for sometime and I let it drag behind.
Regarding licensing, note that Espressif has already submitted an SGA and if there is anything else to be done for the images please let us know.

I'm not entirely familiar with ESP32 yet, but I think this documentation is long overdue. I hope this gets the ball rolling and we can document this better. There's more detailed information on the DevKitC board README which could be ported here, but I think it is best if it is done by someone who knows the platform better and is aware of current status of support (I'm not sure how up to date that README is).

BTW, I can continue working this PR to include more information on other use cases of WiFi (setting up WPA2 would be good to have in the docs at least). But I'm not really sure how that is done nor if the procedure actually depends on ESP32. If all commands are generic maybe this can be done in another part of the docs ("Wireless Subsystem" perhaps)

I have a V2 I believe. It is kind of generic so I'm not entirely sure. The module is WROOM-32 (chip ESP32-D0WDQ6). Flash is recognized as 4MB by esptool. I just re-enabled save params and this is the output I get:

Images are from:
- https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/modules-and-boards.html#esp32-devkitc-v4
- https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/modules-and-boards-previous.html#esp32-core-board-v2-esp32-devkitc
Copyright is defined here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/COPYRIGHT.html
But there's no mention to documentation so I'm not sure if that means Apache applies or not.

I think an instruction on how to erase the flash if things aren't working is enough.
The MTD partition we are using for Wifi data or any other data is part of the main flash. If we erase the flash each time it will erase user data. So if there is a permanent issue, I'd rather we fix it instead.

Ok, I just added a note to recommend a flash erase the first time. Hopefully this avoids any similar issue.
