Improving Wi-Fi file transfer about esp32-arduino-lib-builder HOT 7 OPEN

inside of /home/user/.arduino15/packages/esp32/hardware/esp32/2.0.17/tools/sdk/
a lot of "No such file or directory".

first you need the release/v4.4 branch of this repository, not master. Then edit configs/sdkconfig.common and add the values that you need. After compilation is done, overwrite /home/user/.arduino15/packages/esp32/hardware/esp32/2.0.17/tools/sdk/ with the contents of out/tools/sdk/. You would also need to overwrite platform.txt in the core with the one in the output folder.

Thank you, @me-no-dev , I hope comeback to reveal my progress

from esp32-arduino-lib-builder.

@me-no-dev , I realized that would be configs/defconfig.common, ok?

My challenge:
esp32(as a client) send a file(40MB) to another esp32(as a server), a loop 5KB aftter 5KB at a http.POST(5KB) until finish this 40MB.
But...40MB transfer is taken 7 minutes. A lot o time!!!
How to deacrease this time?

Obs.: I tried to increase this post to 10KB, but the server reset with a "load phroibted".
There are registers in defconfig.common to achieve this?

I'd apreciate your help.

@fjmsouza I think it is not a low level problem, which needs changes here. Probably a bottleneck "somewhere" in Arduino code.

Thank you, @Jason2866!
Me too.

Can anyone give an example with another approach?

The main proposal is a server downloading huge files with better performance.

In the meantime, looking at examples like UploadHugeFile.ino
