Thank you for the quick reply!

The first example, indeed works for me, which means now I have to see what I do differently. Thank you again!!!!

Dear All,
I have been making (old) ESP32 based projects for some time now with no issues, but now I started my first ESP32-S3-mini-1 project and I noticed that the uploaded filesystem does not work.
When I make a simple web server to serve pages from PROGMEM or from an ordinary variable, it works ...

Dear All,
I am fairly experienced in the old ESP32 chips and now I am starting to use the newer ESP32-S3 chips, and in my first project an ESP32-S3-MINI-1. Read all the documentation and datasheet, but I can't get it to start.
I am using The Arduino framework in Visual Studio Code + Platformio.
Here ...

Well, I figured it out:

Previously, I had the following line in my platformio.ini :
board_build.filesystem = littlefs
Once I removed it, I could mount the file system, and my code works as expected. The only minor issue remaining, is that now every time I load a web page, I get the following ...

Dear All,
I have some ESP32 projects I developed in a past few years that I want to bring up to date. Previously I was using older versions of the espressif32 platform, like this:

[env:esp32dev]
platform = espressif32@^3.5.0

Everything used to work fine. When I convert my projects to anything at ...

That's what I thought too at the beginning, because it took me a while to decide on the power supply for the thing on the breadboard.

I checked it with the scope and I can't see any dip on the 3.3V line.

Since then I have been experimenting with it and now I found that if I remove the DC-DC ...

Dear All,

I have built a GPS tracker based on the ESP32.

The circuit is powered from a 12V car battery.
I use a buck converter to produce 4V for the GSM modem. I use another buck converter to provide 5V for the rest of the circuit. I use an LM117-3.3 to provide 3.3V for the ESP32 and the GPS ...

Dear all,
In my project I need to build a small web server which should use GPRS rather than wifi.

I have already implemented the web server, works fine over wifi, but when the wifi is off and I only have GPRS, the moment I issue:
webServer.begin();
it reboots with an exception:
/home/runner ...
