Missing flash.bat and Firmware for BME688 Dev Kit (v2.3.4)

Hello Bosch Team,

I recently downloaded the BME688 Development Kit Software (v2.3.4) and followed the instructions to flash the firmware onto my ESP32 Feather. However, the instructions reference a flash.bat file, which I cannot locate in the software package.

Additionally, the only .bin files provided (v8_context_snapshot.bin and snapshot_blob.bin) do not appear to be valid ESP32 firmware files. When attempting to flash them, I receive "invalid header" errors, suggesting they are not the actual firmware.

Could you please clarify:

Where can I find the flash.bat file referenced in the instructions?
Where can I download the latest firmware for the BME688 Development Kit?
Has the flashing process changed in v2.3.4 (e.g., requiring a different tool or method)?

I appreciate your guidance, as it seems other users are also experiencing this issue.

Thank you for your support!

Best regards,

Robin
