Cannot read files from LittleFS

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 fi...

ESP32-S3-MINI-1 wouldn't start

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...

Re: SPIFFS not working anymore

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 error: ...

SPIFFS not working anymore

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 or ...

Re: ESP32 resets when modem connects to GSM network

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 converte...

ESP32 resets when modem connects to GSM network

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 module....

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/work/es...
