Hello together, I just got a new, preprogrammed BME 688 development kit. If I connect a USB power supply the yellow LED starts flashing. A moment later the red LED blinks 5 times, pauses a while then blinks 5 times again pauses and so forth. However even if I wait several minutes I don't find any data on the SD card except the default config file. Do I need to do any additionals steps e.g. press a button? I didn't connect the Android App so far. Thanks in advance, Tom
