Thanks for the explanation

OK, but it works perfectly with version 3.0.7

I will change this:
xTaskCreate(SerialScan, "Serial Scan", 3000, NULL, 30, &SerialScanTask);
xTaskCreate(ValueRefresh, "Value Refresh", 4500, NULL, 200, &TaskValueRefresh);

to this:
xTaskCreate(SerialScan, "Serial Scan", 3000, NULL, 2 ...

When I upload my sketch to the ESP32, the ESP always crashes. I can only use version 3.0.7 at most. Starting with version 3.1.0, the ESP32 crashes when I run my sketch. In the ...

I could solve the problem. I had to set baud rate to 115200

Ich have a new MacBook M5 with MacOS 26.3.1. My ESP32 Dev V1 with a CH340 chip isn't working properly. On my old MacBook, the Arduino IDE shows the port cu.wchusbserial14100. I can program the ESP through that port. On my new MacBook, the Arduino IDE shows the port cu.usbserial-10. On this MacBook ...

Thanks joydipdns, it works!!
