Excellent. TWO more testers :-) > At first, I had no trouble downloading dives and thought it worked > perfectly.

Yes, the web system they have is terrible.

Yes, there was a really stupid bug in 4.0 that is fixed in 4.1 - but it affected only Windows systems, which is why I never saw it (as I usually have no Windows machine to test with (and neither does Linus)). > FWI, he and I were both using Windows based laptops for > this.

I'm so sorry - you guys should have reported this back then and hopefully I would have figured out the bug earlier. > One thing I would really really like is a capability to output a diagnostic > log during the SDA download step so that at least I could see how far it > got and where i hangs. Subsurface claims to be able to do this, but AFAIK > this capability does not actually work. It only works for dive computers where we use libdivecomputer to download. I guess I need to implement this for the Uemis SDA as well. :-/ > Also, I've noticed that if there is > one good thing about the Uemis web-based divelog it's that it can download > essentially any number of dives without choaking and hitting this out of > memory error (SDA file system full) that Subsurface often hits. No that is not true. This is a hardware limitation. Depending on how long your dives are, it can download about 60 dives in one setting - just like Subsurface. But you never run into the problem as almost no one does 60 dives before they first connect to their web system. But this is indeed a design limitation of the software on the SDA. And I have been able to reproduce the problem with their web software as well. Only the web software gives you a really bogus "timeout" error message - but you still need to disconnect and reconnect the SDA in order to reset the file system (I can explain what is really happening if you are curious). > I would > like to look into that to see if it's possible to improve the Subsurface > download process.

I am 100% certain about this. > I'm sorry, but looking at what I've wrote, I don't think it offers much > concrete to describe the problem.

No worries, this was really useful. > In any event, it's great to know there are allies out there with SDA's, and > that you and Linus are among them. The SDA is a great computer! I love it - even though I have about a dozen dive computers at my disposal, the SDA is still the one that I usually "dive" (i.e., even when diving with three or four or more computers, like I usually do, the SDA is the one that I pay attention to). The exception is of course when I do trimix dives - sadly they never implemented that. /D _______________________________________________ subsurface mailing list [email protected] http://lists.hohndel.org/cgi-bin/mailman/listinfo/subsurface
