Trying to upload a picture, ESP32 Cam -> local ftp server

[ldab]

Please share you full code.

Start the library with verbose mode "2" and share the serial monitor.

Since the example provided with the library works, it's likely that your code break due to the use of SD card or the EEPROM

Thanks for your reply!

After re-uploading the sketch today I unfortunately didn't manage to come as far as yesterday (the code breaks before making the connection) and indeed it seems to be related to the SD card as you said.

Here is the code below:

I would recommend trying the example you shared on the first link sent and go from there. I'll close the issue as it does not seem to be related with this library, you're welcome to open again if you find that the library is breaking something
