I do not get you. I'm sorry. Anyway I miss form my logbook only the last newest dives. So I do not understand why it's not possible to save them to a temp location and then parsing what's good from the partial download. My download stops after the newest 10 dives and I need only the first three. > > Note that subsurface also has another related problem.

I had problem in the past trying to download dives from several rebreather with ctool no matter the OS I was using. I spent 50€ of saft batteries to download them. Now the problem is downloading dives from my petrel via Subsurface mobile. -- Davide https://vimeo.com/bocio/videos _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
