After platformio.ini changes the OTA binary flash does not work anymore.

Hi, after your changes in the platformio.ini file, the OTA Update returns with an 400 HTTP Error containing following response: "OTA could not begin".

I was tracking this issue down to the change where you switched a lib_dep from "https://github.com/me-no-dev/ESPAsyncWebServer@^1.2.3" to "me-no-dev/ESP Async WebServer@1.2.3"

After the change the lib loaded "ESPAsyncTCP@1.2.2" AND "AsyncTCP@1.1.1" while the old dependency only fetches "AsyncTCP@1.1.1" and omitting the "ESPAsyncTCP" library...

Here is a trace using "me-no-dev/ESP Async WebServer@1.2.3" Library Manager: ESP Async WebServer@1.2.3 has been installed! Library Manager: Resolving dependencies... Library Manager: Installing ESPAsyncTCP Unpacking [####################################] 100% Library Manager: ESPAsyncTCP@1.2.2 has been installed!

and here the trace using "https://github.com/me-no-dev/ESPAsyncWebServer@^1.2.3" Library Manager: ESP Async WebServer@1.2.3+sha.f71e3d4 has been installed! Library Manager: Resolving dependencies... Library Manager: Installing me-no-dev/AsyncTCP @ ^1.1.1 Unpacking [####################################] 100% Library Manager: AsyncTCP@1.1.1 has been installed!

I know the ESPAsyncTCP IS used in the code, and NOT the AsyncTCP (since the later one is not used in esp8266 afaik) and I really have NO clue why it still works even when the ESPAsyncTCP is NOT loaded as dependency... I guess it is included in the GIT (dev) version, but NOT in the Release ?

Nevertheless, this change causes a file size change of the resulting firmware binary from ~447k to ~645k.

I have no clue if I´m correct here, but I think this is the issue why ElegantOTA is not able to flash the binary file...

Hey appreciate you doing all the digging. I'm fighting the same issue myself right now though I found some other ways to reduce the binary bloat. I'm on it, cheers!

Fixed.
