Hi,
I have the same problem, but for some dives I found a solution to import them successfully.
- Export a single dive from Diving Log to .fit
- Fail to upload
- Check with
https://www.fitfileviewer.com/, which states an error and download the fixed version
- Succesfully upload the fixed fit
Due to the lack of precise error log, I think its hard to find the bug with the export.
So here is a fit file generated by dive log and the fixed version from
https://www.fitfileviewer.com/which successfully uploads. Once processed by fitfileviewer, it uploads. But you can only process files with errors there.
Hope it helps, I would love to import all my dives to Garmin too
