I've recently upgraded my iX3M2 Pro, replacing it with an iX3M2 GPS Deep. The
first two dives downloaded just fine via USB cable a couple of weeks ago, and
today went for a third dive, but I haven't managed to download. I've tried a few
things:
1. Download using Ratio Toolbox - worked.
2. Download via USB cable - didn't work
3. Download via USB cable using an empty logbook - didn't work
4. Download via USB cable on a different computer - didn't work
5. Download via BT on a laptop - didn't work
6. Download via BT on androis - didn't work
In all cases, where it didn't work, it started downloading - read the serial
number, gave me an error message:
"Dive 1: Error parsing the header", and then repeated for Dive 2 and Dive
3.
Then proceeds to tell me there were no new dives to download. I've tried a
number of the different iX3M and iX3M2 models to see if that changes anything,
but appears not. Also no different if I check "force download of all dives" or not.
Which version of subsurface you are using? I suspect you have a version without
this fix:
https://github.com/libdivecomputer/libdivecomputer/commit/e1762fc8bddf9d742387617f87b990729c0e482f
The format changed in a non-backwards compatible way in the latest firmware, and
this fix is needed to parse dives using this new format.
Before sending through the entire libdivecomputer log, maybe someone can help me
by pointing me in the right direction from what appear to to be the relevant
snippets. I notice that the error messages refer to src/divesystem_idive.c
I'll need the full libdivecomputer log to confirm whether this is indeed the
problem or something different.
BTW, those NAK errors you see in the log are harmless and can be ignored. That's
simply the dive computer saying it's still busy, and we need to wait a while and
retry, which we do.
