[FEATURE REQUEST] Support for BTT SD Cloud V1.0 / FYSECT SD-WIFI

[rafaljot]

I ordered this $10 module for test.

Do you know if there is any specs / documentation / source code ?
I saw this on FB but I have no idea how it works

[luc-github]

@rafaljot I do not think I can do anything it is only connected to SD no serial communication with printer
it is a WiFi SD

[rafaljot]

I hope BTT will publish a schematic of this module soon, just like SKRs (https://github.com/bigtreetech ) . Even if not, it is very simple.

I don't think it is only remote-SD. We can use USB to connect to printer. It looks like there is ch340 chip on board.

[luc-github]

the USB is to flash the FW - I do not see how the usb will be able to communicate with printer - none of them are usb host

[rafaljot]

I think it is something similar:

[luc-github]

yes I know this one, the project is not really new - ESP3D do not support this way to hook the SD card , it is not reliable for me to control properly the sharing
you see usb is for PC - so BTT is a wifi SD not a printer controler

[luc-github]

I close topic as no info about hardware/fw feel free to re-open if any update on it

[luc-github]

I got one device and I will received also the FYSECT version
I have flashed the BTT device with FYSECT FW and it is working so it means they 100% pin compatible
https://github.com/FYSETC/ESPWebDAV

Now I have enough info I can work on this
Also there is a webserver hooked version which is not sticked to espcore 2.4 https://github.com/d-a-v/ESPWebDAV/tree/v3
so it should be funny to play with and do porting :

put this on BTT TFT 3.5 is not working well:

• if connected when boot start it says workibng on it then Marlin is reading from SD Card, if refresh windows, it is fine and list all SD content
• if check sd content from TFT then SD is no more accessible it says workibng on it then Marlin is reading from SD Card which is normal but after refresh it says This folder is empty so no more Sd content is available
  => solution reset TFT then WiFi can access again...

I am guessing the tft do not release the SD after query it unlike it is done at start, so BTT FW may need tuning ....

this would be very interesting if only uploading is working for the beginning and i could start print from the ESP-01 at BTT_TFT35_V3_E3 or directly from the Touchscreen. Tried your ESP-Firmware, but couldn't read from the SD-Card at the BTT_SD_Cloud at the user interface. the original-firmware from BTT is not working for me

[luc-github]

no the esp3d does not support this hardware, original FW from BTT and the one from FYSETC is not really working for me neither as mentioned above

@luc-github it should be possible to add usb-host support with the software driver https://github.com/cnlohr/espusb
GPIO2 and GPIO15 look like they might be available for some patch wires.

[luc-github]

this is not usb host, it is emulate block device like keyboard or mouse
why would you need that on sd wifi ? it already has usb connector on btt and fysetc one

An usb-host support to connect a printer to esp is not that easy ( or I would do long time ago 😸 )
like connecting on PC each device has different driver so even connected they are not able to communicate if right support is not there.
please check this thread : #424

@luc-github Hmm, Yeah you are right, apparently I've googled esp8266 usb-host and got to the espusb page without checking the detail. I thought it was a software implementation of the shield as discussed here: https://www.hackster.io/139994/plug-any-usb-device-on-an-esp8266-e0ca8a
