Unfortunately, DiveMate won't help me at all. It is only mobile device based. I need to get access to the full logs on my computer (desktop when at home and laptop when away). I can't see anything on their site that suggests I'd be able to get the logs from a mobile device to my computer.
I also wonder that even if/when they support the MK1 whether they will pull the data directly from the device or pull it from Garmin Connect. If the latter, it won't solve this problem. Are there any apps out there now that can pull activity data directly from a Garmin device in the same way that GCM does?
Is Subsurface likely to be able pull the data directly from the MK1 or will it pull it from Garmin Connect? Do Garmin even publish away to pull activities directly from their device (other than directly accessing the FIT files via USB Mass Storage mode)?
My changes are going to be to the desktop application, and allow the logs to be parsed directly off the watch. There is additionally a Subsurface mobile app, which would sync to the descent via bluetooth. That is a stretch goal for me, but would likely need some community help as I'm not a mobile developer.
