Could you send me or share your logged file for testing?

Before we work out the solution, a workaround is parsing NMEA with TinyGPS library in ATMega328p.

With 6-axis or 9-axis?

That might be a bug in the parsing code (in firmware). We will look into that. Are you having 5Hz or 10Hz GPS module?

Red is for power. Blue is for data.

If you GPS data in KML, check if there is GPS data in CSV. If not, GPS might not be detected or GPS data logging is disabled.

Files are not dated as there is no API for doing this in Arduino's SD library.

If you register before placing your order, you can log into our online store and see the status of your order.

It's done by serial communcation with documented AT command-set. Any language can do that.
