I've just dome a couple of dives with a computer that's recently been updated from 3.17 to 3.18 and the download looks a bit odd.
In Subsurface with 3.17 the 'extra info' for the computer used to say:
FW Version 3.17
Deco model ZH-L16-GF
Deco model info GF 30/85
Now with 3.18 i see:
FW Version 3.18
Deco model ZH-L16
Deco model info Saturation 77, Desaturation 78
The dive computer itself seems to think it's still in ZH-L16-GF with gradient factors 30/85, nothing has changed on that front other than updating the firmware.
Is deco model correct in 3.18?
Is deco model correct in 3.18?

Hi,
Nothing has changed on this point between 3.17 and 3.18.
What Decotype is stored in the internal logbook?
regards,
Matthias

Re: Is deco model correct in 3.18?
Internal logbook seems to look correct (I didn’t think about looking there). Hopefully this is just a display thing then.
I’ll maybe the an old version of Subsurface to see what that looks like on there.

Thanks, looking at this I think it’s something broken on the Subsurface end.
Downloading my old dives using older firmware versions also displays this issue on the current Subsurface but if I step back and use an older version (only tried 5.0.5 so far) they all download fine.
I’ll raise this directly with the subsurface devs

Re: Is deco model correct in 3.18?
I looked into this a bit. I'm not sure about the earlier version, but checked the hwos_interface.pdf in the hwos source tree. It seems like libdivecomputer is using byte 82 (Dive mode), which is 0 for OC and 1 for CCR. Instead of byte 79 (Deco model), which is 0 for ZH-L16 and 1 for ZH-L16-GF.
There is another problem, for the Saturation / Desaturation information it uses the byte number (77 and 78) instead of the contents for those bytes. Otherwise it would probably have shown saturation as GF low and desaturation as GF high.
So if you're diving CCR with ZH-L16-GF you would get the correct information.

Maybe this will fix it: https://github.com/subsurface/libdc/pull/32
