I quit the download before getting errors and draining my battery. At the end of the libdivecomputer file I find:
WARNING: Disabled all O2 sensors due to a default calibration value. [in /home/travis/build/Subsurface-divelog/subsurface/libdivecomputer/src/shearwater_predator_parser.c:503 (shearwater_predator_parser_cache)] INFO: Write: size=9, data=FF0105002E902000C0 Exactly the problem mentioned by Anton. Could someone explain me what does it means? Is it a way to avoid displaying wrong pO2 samples due to the previous problem? What can I do? Is it my fault? Is my Petrel defective? Why in my logbook I find 4 different computer names with different attributes if my unit is always the same? <divecomputer model='Shearwater Petrel 2' deviceid='1a2d46b1'> diveid='3db7eb77' dctype='CCR' no_o2sensors='1'> <divecomputer model='Shearwater Petrel 2' deviceid='1a2d46b1'> diveid='52d4ba3e' dctype='CCR' no_o2sensors='3'> <divecomputer model='Shearwater Petrel' deviceid='1a2d46b1'> diveid='a6e05a10' dctype='CCR'> <divecomputer model='Shearwater Petrel 2' deviceid='1a2d46b1'> diveid='3db24900' dctype='CCR'> Are those differences due to subsurface history reason?
