Does anyone here know how to edit .fit files?

I have the FitSDK and fitCSVtool. I'm trying to make a hybrid Backcountry Ski bike activity that is basically backcountry ski but uses the Bike HRM settings. I don't suppose anyone here knows how to do it?

I don't know about the FitCSVtool for writing FIT files, maybe someone else does.

Figuring out what undocumented fields are for, can be hard. Comparing CSV's made from several sports profiles might help. From memory, you could create sports profiles with the (Java) FIT SDK, but you'd have to consult the documentation to check, because it is many years ago I worked with it.

I'm not sure how to get new sports profiles accepted by the watch, I could not restore sports profiles from a backup a couple months ago (but that could be due to the lower limit on sports profiles at the time).

Other alternative is copying Other and edit it to have as much of the functions you can get into it. "Other" is generic enough to work for most sports, except very slow moving like open water swimming.

You can't really create a new activity profile by editing FIT files. What you need to do is install the Connect IQ SDK and then build a new device app.

Or if all you want to do is change how heart rate is displayed in the Backcountry Ski activity profile then you can just add a new custom data screen for that.

I know what data screens are, thanks. I'm trying to splice together a profile that'll give the correct OHR until Garmin fixes the bug they introduced in v24. Thanks for the pointer to the Connect IQ SDK.
