Issue Flashing SomfyController.onboard.esp32.bin to T-Internet-POE

Hello everyone,

I am unable to flash the image SomfyController.onboard.esp32.bin onto the T-Internet-POE. I am using the expansion board for flashing and the ESP32 Flash Download Tool on Windows.

What do I need to do to successfully flash the image onto the T-Internet-POE?

Thanks,
Jürgen
