The problem I configure 3 UART instances on a ESP32 (see YAML below). One for P1 DSMR (utility meter; electricity) Two for Multical (second utility meter; district heating) Logger UART is disabled ...

I have also written short Arduino code which accomplishes same thing and it works as expected. I have also tried disabling logging UART, but that has made no difference.

When the code is uploaded via serial port, it creates a web server where you can choose and upload a new sketch via a web browser. To upload the first code, connect the ESP32 to the laptop and open ...

Arduino Integrated Development Environment (IDE) simplifies programming, uploading code, and utilization of ESP32 capabilities, enabling users to incorporate it into their IoT projects with ease.

As just noted in my article about LILYGO T-32C3 module, the ESP32 Arduino 2.0.0 release happened a few days ago adding ESP32-C3 and ESP32-S2 support to the Arduino IDE. But the news probably warrants ...

The Arduino IDE 2 offers plug-and-play support and even debugging without requiring external hardware. The official ESP32 core for Arduino can be used too, and the board is compatible with the Arduino ...

Bojan Jurca's "Esp32_oscilloscope" is an open-source Arduino sketch that can transform an ESP32 board into a web-based oscilloscope that works over WiFi.
