BME 688 I cannot find raw data on SD card

[sotan]

Hello, 

I tried BME688 with Adafruit board, but I could not see any raw data. Here is what I tried.

• Assembled BME 688 dev-kit and Adafruit HUZZAH32 feather board.
• Copied *.bmeconfig file into microSD card (SD card was eFAT format).
• Inserted microSD card into Adafruit board.
• Put CR1220 coin cell into BME 688 board.
• Connected board to Windows PC and installed USB driver.
• Run "flash.bat" on PC. It was successfully finished. 
• Plug out USB cable.
• Provided power from USB cable. Red LED flashes very quickly. (Seems no change??)

What was wrong in my process?

Hi BSTRobin,

Finally I could solve the problem. 

I tried another micro-SD card, and that seems good. There were not any error in teraterm and I could find raw data in micro-SD card. 

Thank you very much for your support.

Hi sotan,

Good news. Thank for your update.

The BME688 dev kit comes with micro-SD card. Do you mean that you can use it normally after changing another micro-SD card?
