How can I open this file to see the raw data of the HR values?
my two cents and sorry for the technical bla bla bla...
the raw data
open the mmmmm.fit file with a hex-editor
search…
Just to clarify what you are asking.
You mentioned you had a Fenix 5 so I assume you are wanting your HR data from a fitness activity (run, etc.) rather than a dive.
I’m pretty sure that a fitness TCX…
I wish TCX files were available for dives.
activity change to swim does not help ?
goes not, 2 years ago there was a similar question... export-tcx-file-of-diving-activity-from-garmin-connect
Yeah, that was me asking.
For updating. After download "thisisant FIT SDK" run the FitGen.exe, later that, look for FitToCSV.bat in the java folder in the same location and run it in CMD terminal like:
C:\.......\java\FitToCSV.bat mmmmm.fit
mmmmm.fit is the file from Garmin Connect
After run FitToCSV.bat mmmmm.fit you will get mmmmm.csv with all your raw heart-rate data.
