ESP32 2.0.2
Beim ersten Versuch einen ESP32 in der Arduino IDE zu programmieren, hätte ich die ESP32-Boards-Version 2.0.2 versucht:
URL: https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html
Mit dieser Version war es mir nicht möglich den WiFiClientBasic-Beispiel-Sketch zu kompilieren:
collect2.exe: error: ld returned 1 exit status error compiling for board esp32 Dev module
Error compoing for board ESP32 Dev Module.

Test mit ESP32-C3
Compile erfolgreich, aber,
A fatal error occurred: This chip is ESP32 not ESP32-C3. Wrong --chip argument?
Version 1.0.6 funktioniert
Folgende URL "https://dl.espressif.com/dl/package_esp32_index.json" und Version 1.0.6 hat dann geklappt:
Wichtig: Ordner 2.0.2 löschen:
Sind mehrere Versionen eines Paketes installiert, müssen die Ordner eventuell aufgeräumt werden. Um die Version 1.0.6 zu verwenden musste ich den Ordner 2.0.2 löschen:
