Import dives from Cressi Cartesio

[Martin de Weger]

That sort of sucks. :(

I’m happy with the fact I can download the dives using USB on my Mac now, so that is a win… ;) Thanks for the help so far! I have been looking into finding the BLE packet, but am not able to find a way to do so.



Kind regards,

Martin De Weger
