Re: Is there a way to have ESP32 send its logs to a web server?
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.

Re: ESP32-S2 reboots when WiFi is used
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.

Re: Access Linux shares from ESP32
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.

Re: Struggling to get stable WiFi connection on ESP32
I have experienced problems with the wifi timing out if not used for a while,
I fixed this with the command: WiFi.setSleep(false);

Re: Realistic for webserver to run on ESP32 24x7?
Hi,
I have had similar issues in the past and it was resolved by including the command: WiFi.setSleep(false);
may be worth trying?

There are ebay sellers who supply them with an external antenna, maybe message one to ask if it is ready configured?
