It looks like this is yet another case of a corrupt ringbuffer begin
pointer:
ERROR: Invalid logbook pointer detected (0x0240 0x0a30). [in
../../source/src/oceanic_common.c:218 (oceanic_common_device_logbook)]
ERROR: Error downloading the dives. [in
../../source/examples/dctool_download.c:218 (download)]
ERROR: Data format error
Since this "bug" (a firmware bug probably) shows up quite often, I have
been looking at possible solutions already. I have some ideas on how to
modify the download algorithm to no longer depend on the begin pointer.
But at the moment that work isn't finished yet. It works most of the
time, but it also causes some regression for others. So it needs some
more polish.
