I have a host application that will keep a date/time stamped log of people entering a doorway.
The project hardware has a ESP32 fitted with the aim of being able to obtain the log remotely using a mobile phone, tablet or PC wifi.
I can generate a comma delimited log on the host machine ok.
The end result is I want the user to be able to get the data from the host to a PC to view as an excel file, so I am looking for “simple” ways to achieve this. I can set up an ESP32 as a web server ok but not sure how to transfer the data.
Basically, it’s missing the “download the file remotely stored in the ESP32 using a web server”… Unfortunately I don’t have any tutorials on that subject, but I recommend watching this video:
- Video: youtube.com/watch?v=6XR6BXbc0aI
- Code on GitHub: github.com/G6EJD/ESP32-8266-File-Download
That example should allow you to download a file stored in the SD card remotely through an ESP web server. I hope that helps!
