Which external GPS logger can I connect to the Panasonic Lumix G9 for real time geotagging without a smartphone?
With external GPS logger, I mean devices like
- Qstarz GPS BT-Q1000XT
- TSI GL-770
Currently I use a Garmin GPSMap to track the position and tag the photos offline while post processing the exif tags with Digikam and similar tools on Linux.
Is there a specific protocol which the GPS logger needs to support?
