ANT Forum

All the forum posts, are about consuming FIT files, usually generated by things like Garmin 520 etc.

I can't figure out from the docs how to _generate_ a FIT file. Are they constructed of rolling 1 second averages? Does one use the SDK to write the FIT file too?      

Hi,

I'm writing FIT files during export of workouts in my Android app "myWorkouts".
I'm using Java (obviously) and the FIT SDK. (Without this, it's really pain in the a... to create a valid FIT file.)
The problem is: they are not uploadable to GarminConnect.
Strava accepts them, but Garmin not.
It's very frustrating for me and my users because I don't get support from Garmin.
Without any further information, the upload just says: "An error occurred with your upload. Please try again."

For non GPS workouts I export rolling intervals (like 1sec, 2sec, depending on workout duration).
For GPS workouts, I export one item for each GPS reading.

I hope this helps.
