If anyone manages to figure out the gps props for the 6d, I'd like to include this in a module:
1. Adapt the satellite fix time according to the camera idle time, i.e. get new positions fast when the user is obviously doing something with the camera, but lengthen the intervals when the camera is doing nothing to reduce battery drain.
2. Auto-disable on shutdown, (re-)enable on startup to prevent battery drain when forgetting to switch gps off.
Any other ideas on what to do with gps are welcome.
