Thanks, Is there a way of setting this in the sketch as I want my sketches to work for people whichever version they have installed?

I have discovered that my sketches using the ESP32 watchdog timer no longer work. After some time I have believe I have figured out the fix for this and passing it on in case of help to anyone else (or if anyone has a better solution?) also v3.0.0 seems to use a lot more memory so I have had to chan...

Hi,

The easiest way I have found is this: https://randomnerdtutorials.com/esp32-c ... to-server/
although I don't know how secure it would be

Another option would be to have it FTP the files (there are libraries for FTP)

or failing that it could email them to you.

I would suspect the power supply to the esp32 as I have had mine do the weirdest things when they are not happy with it.

An interesting way to easily transfer files which I have used and may be of interest is to install Apache on your linux computer then us a php script.

I have experienced problems with the wifi timing out if not used for a while,
I fixed this with the command: WiFi.setSleep(false);

Hi,

I have had similar issues in the past and it was resolved by including the command: WiFi.setSleep(false);
may be worth trying?

ULP may be a possibility?
