Hi – I have an ESP32 with an SPI SD card reader. SD cards are formatted FAT, and I can read and write files.
Now I need to copy a file from the ESP32 to my Windows PC, via OTA. What is the best and simplest way to do that?
(If there is no OTA for this, then wired via native USB will do.) Thanks!

Hi.
There are many different methods to send files to the ESP32, but I’m not familiar with any method of getting the files via OTA. Maybe with an FTP server would be easy to get the files from the ESP32 wirelessly.
I found this video that might help: https://www.youtube.com/watch?v=2GwzbBn7uRw
I’m not sure if this is what you’re looking for, but I hope it helps.
Regards,
Sara

Hi Sara, maybe OTA is the wrong term. I should say WiFi instead.
I am sure HTTP will do, but something simpler and less clumsy? FTP as you say, and I will look into that.
Best would be a remote file system for FAT32. Is there an ESP32 library that will mount the SD drive on the network, like you can do with a PC? I am sure there is one, but I have not seen it in your large collection of packages.
Thanks

Hi.
We don’t have any tutorials about that specific subject.
Try a search with the following terms: “esp32 ftp server sd card”. You’ll find some examples that I think might suit your needs.
