Hi there, I hope I'm not to late. I can't get the app to work as well with the same error message. Actually I alread tried reflashing the ESP32 but this didn't help. The only conf+bmeconf which work are the ones provided with the BME688_x8Board_v1.5.0 software folder. But of course I'd like to train and use my own data and conf and not only detect H2. Is the older Version of AI Studio available somewhere? Version 1.5.5 seems to work just finde with 1.5.0 board software. Best regards Benjamin
