Issue Parsing #41

Closed mornindew closed 2 years ago

mornindew commented 5 years ago

First of all, I want to thank you for this project. It is very well done and super useful. Thank you very much. I might even be able to break off a couple cycles if that helps you to keep maintaining it.

I am having an issue with a FIT file that I downloaded from garmin. Running your "Example_test.go" with my file when I parse the fit file I get...

parsing data message: missing data definition message for local message number 10 It was a fit downloaded directly from garmin. I don't fully understand your fit decoder yet to be able to debug it. Have you seen this before? I included the fit file if it helps. Broken.zip

Hi. Thanks for the example.

Your file is parsed successfully by the official SDK tools, so the decoder is clearly missing something. It should parse a definition message for the Record message next.

It seems like the file contains "Developer Data Fields". Support for this is not implemented yet (see #21). That may be the issue.

I'll try to take a closer look at a later time.

mornindew commented 5 years ago

I appreciate it, I will try to diagnose on my end as well.

Got the same error:

parsing data message: missing data definition message for local message number 15

my .fit file parses OK with the official tools (version 21.smth) and it contains Developer Data Fields (via Stryd I guess).

I tried to generate the code via fitgen from version 21 SDK, but that failed as well.

@mornindew what did you end up doing?

Thanks!

tormoder commented 4 years ago

I have not checked the spec in detail, but I think it's it likely that parsing fails since Data Developer Fields are not supported (#21).

Unfortunately I don't have the time to work on that now or any time in the near future...

Just adding a data point: I'm seeing the same error message with a fit file from a Wahoo device, exported from Strava.

It there a way to just skip reading those fields ?

tormoder commented 3 years ago

Yes, I'll add that soon, either via https://github.com/tormoder/fit/pull/59 or a separate change.

tormoder commented 2 years ago

Better late than never.

Decoding the files mentioned by @mornindew and @aurelian in this issue should now be possible to decode using the latest release (v0.13.0).
