Release request

I just realized my dive computer is supported in in git trunk, but there hasn't been a tagged release in a LONG time. Comparing the supported devices list between stable and trunk implies a LOT of users would be in a similar state. Any chance we could get a tagged release soon on a particularly stable, recent version of libdivecomputer. At the least, that would really help with packaging concerns, etc. I have the latest git compiling, but when I attempt to import dives in subsurface 4.4.2 from my Aeris A300 CS, I get a parse failure. My extremely limited understanding is that is handled within this library. If this should already be working in the current trunk, I'll gladly go through some information gathering, submit a report with logs, etc. I'm personally trying to get an Aeris A300 CS working with latest subsurface. Once I do so, I'll get with the current Mageia maintainer and see about getting an update pushed out to cauldron for testing.

Hi, I didn’t had much spare time in the last weeks, but I kept thinking about the idea of representing repetitive dives on libdivecomputer Initially I wrote a simple spreadsheets to summarize the pros and cons of possible approaches . Colors represents the “severity” of a drawback or of an impact and are my guesses. We may use it to confront ideas. Generally speaking I think that the API should really include a way to pass free-form data to the app, while right now everything is codified in the "least common multiple" of all the DC capabilities. It may seems a weird thing to do, but consider that each dc may have specific information which the user (who chooses and bought that DC) may want to be represented on the profile. I am thinking about alarms and statistics, and also the whole “subdive” stuff. It could be a good idea to introduce some kind of USER_EVENT (or USER_SAMPLE) with name, type (int, float, bool, string) and value fields. Parsers should use the USER_EVENT to report info which the app may choose to skip, draw as it is or elaborate. Then we may define policies on such events. Such that 'alarms name shall start with "AL_'" or similar to hint the apps. This would be, in my opinion, a progressive and low-impact way to improve flexibility of the API. Referring to the attached table, such change would allow for a simple a straight forward implementation of the workaround for the drawbacks of the “Merge Subdives” approach or for the whole “report session and dives in an unstructured way” stuff. Let me know what do you think about it. G

No p02 for Petrel (Divecan)?
by "Paul-Erik Törrönen" 19 Oct '15

I noticed an oddity when downloading dives from a rEvo RMS Divecan Petrel, the dive data did not contain any pO2-data. This was with the latest daily build of Subsurface, 4.4-98-56 on Windows XP When I downloaded the same dives to Shearwater Desktop (SD), it did contain the actual pO2-data, so the dc has stored the data, and it is present (for all 3 O2-sensors) when I eg. export the data from SD to CVS-format. I noticed another peculiarity. Subsurface recognized the dive as OC, when it should have been CCR. I guess the detection is done earlier, and I found from the maillist archives[1], that when the dive is presumed to be OC, no pO2-data is collected by libdivecomputer. Maybe there's an issue on how the OC/CCR-mode is detected? I had to return the rEvo today as it was borrowed, so I can not immediately verify anything, the unit however is not that far from here, so I may be able to do testing. Partially related to this: There are instructions on how to capture the traffic between the DC and log software, but this seems to only work in those cases where the DC talks over the serial. In my case the Petrel seems to have been accessed in a more direct manner (there was no COM-device) and portcom was quiet the whole time. Is there a recommended way to capture the transmissions from Bt-devices? I tested with sniffusb which seemed to capture something (since the Bt is apparently connected to the USB-port), but I'm not that sure I got the correct data?

Hello all! This is totally awesome! :-) Is it possible to send commands to the Vyper in any way? Ex. to reset the computer or to change values? Thanks in advance! - Covey
