Looks like you have a Garmin device I haven't seen before. Which device do you have?

If you have further issues, you might want to share a fit file with me and I will work through any remaining issues.

Hi, i have a Garmin 630 Forerunner unit, plus a Stryd Power Meter. Perhaps its that some metrics come from Stryd that are doing it?

I tried to send a fit file here but couldn't, i sent it to email

[tcgoetz]

I received the fit file and will make sure there are no issues supporting it.

[tcgoetz]

Did you use the Stryd Power Meter for the activity that file was from?

I don't see it in the file. I see:
GarminProduct.Forerunner_630
GarminProduct.GPS_1619
GarminProduct.HRM4_Run
GarminProduct.Accelerometer_16
GarminProduct.fr225_single_byte_product_id

Maybe the Stryd impersonates a HRM run.

[sis9]

Yes, i did. But i am not sure if this is the reason for not working.

The metrics from Stryd are Connect IQ datafields: Power, Cadence, Ground Time, Vertical Oscilation, Form Power etc.. Note that there are dublets (ex Cadence from 'normal' watch and Cadence from Stryd Connect IQ field)

[tcgoetz]

Here are the dev fields being parsed form your file:

Power, Cadence, Ground Time, Vertical Oscillation, Elevation, Form Power, and Leg Spring Stiffness

They are currently being parsed from the FIT file and are present in the fit file output, but are not being put into the DB unless they share a name with a field from the HRM-Tri. I have to think about how to store fields that are present for only some users.

[tcgoetz]

Lap messages from your FIT file supply the same fields as the HRM run. Those will appear in the DB already for runs. There are addition stats in the record entries that can be added to the DB. Please file an a new issue if you want those in the DB. If you want these stats to appear for walking activities, please file a separate issue for that.
