#13: Mares icon HD black: Bad profile import -------------------------------------+------------------------------------- Reporter:| Owner: jefdriesen Bushi | Status: new Type:| Component: Device communication defect | Keywords: Icon, mares, profile Priority:| major | Version:| 0.4 | Plattform (please give specifics in | the ticket text): Windows | -------------------------------------+------------------------------------- Mares icon HD Black: firmware 4.1 Import of dive from icon to window 8 pc resulted in scary incirrct profile. Profile on pc show drop to 600ft then rocket to surface in middle of profile. This shows if I import with mares dive app, subsurface & dive log 5. This drop dose not appear on icon profile, further if I import to Mac aplications, subsurface or mares dive diary, the drop in profile dose not appear. Somthing about importing on the pc or how data is parsed seems in error.
Not sure what is best to attach Thanks

Comment (by jefdriesen):
Can you attach a memory dump (and corresponding logfile) from your dive computer? In the subsurface download dialog enable the two libdivecomputer memory dump and logfile checkboxes. Attach the two files to the ticket.
Some screenshot might help too.

Comment:
It seems that the problem is caused by data corruption during the download. This has been confirmed by doing multiple successive downloads from the same device, and comparing the memory dumps. Some data packets are not identical, and those packets are located in the dives that fail to parse correctly.
The Icon HD protocol doesn't use checksums, so we can't detect corrupt packets and unfortunately there is nothing we can do about that.
