Attempting to process .fit files that I downloaded off of Garmin Connect from my HRM Pro Plus.
Using Python SDK.
However, when I use the example program, decode throws an
[KeyError('struct_format_string')]
error.
Curiously, it seems to work fine on the example .fit files. Is there something wrong with the .fit files themselves?
Addendum: is_fit() returns True. Further, I previously used the FitToCSV program to process them, so they should be valid files...
Not sure what is going on here.
