Hallo zusammen,
ich hab ein dolles Problem: ich kann keine ESPs mehr programmieren…
Seit 2025.9.3 bekomme ich dieses Problem:
Reading CMake configuration...

========================== [FAILED] Took 4.97 seconds ==========================
Dabei habe ich nur einen neuen ESP angelegt und diese drei Zeilen angehängt:
esp32_ble_tracker:
bluetooth_proxy:
active: true
…auch ohne die drei Zeilen, quasi der “Standard”, kann nicht mehr kompilieren…
ChatGPT schreibt hier:
AttributeError: ‘NoneType’ object has no attribute ‘validation_alias’
Ursache: ESP-IDF 5.4.2 nutzt die Python-Bibliothek pydantic für das Component Manager-Tool. Laut Log benutzt du Python 3.12, ESP-IDF 5.x unterstützt offiziell nur Python 3.10. In Python 3.12 gibt es Kompatibilitätsprobleme, daher bricht das Skript ab.
Da steige ich allerdings aus, wovon hier geredet wird. Wie kann ich das Problem beseitigen? Mit Arduino Framework statt ESP-IDF gehts, aber da gibts diese Meldung (kein Abbruch):
WARNING Bluetooth Proxy with active connections on Arduino framework has suboptimal performance. If BLE connections fail, they can waste connection slots for 10 seconds because Arduino doesn’t allow configuring the BLE connection timeout (fixed at 30s). ESP-IDF framework allows setting it to 20s to match client timeouts.
Danke Euch!
