Upload to printer SD in V3.0

[RoP09]

I'd like to upload files to the printers SD through ESP3D even if it is slow, but somehow the menu item for upload is not visible once I switch to printer SD. I can start prints or delete files, but upload is not possible.

Has this to be enabled in the configuration.h file somehow? I was looking there but could not find any suitable define
(this is on ESP3D 3.0 and Marlin/Jyers FW on a Creality Ender 3 V2 4.2.2)

I would honestly recommend you scrap that idea because, yes, it IS SOOOOOOOO slow.

Get a FlashAir WiFi SD Card instead and an microSD to SD adapter. Transfer your files from anywhere wirelessly to your SD card directly.
Have a look here - https://blog.prusaprinters.org/easy-wireless-printing-with-flashair-sd-cards_8603/
It's what I do. So much faster than ESP3D

@RoP09 I have updated the status of V3 : #540 (comment)

UPLOAD_SERIAL_SD (implemented in 2.1 but not available yet in 3.0)
the access to SD is done using M28/M29 protocol
e.g: Default 3D printer protocol

It is too slow and ask a lot work depending FW, also now this upload is almost always corrupted when using Serial TFT so it is pretty useless for most of people,  so I won't implemented it.

I prefer to spend dev time on  https://github.com/luc-github/ESP3D/issues/575 instead, to have real benefit, and no more data corruption due to external queries
