Calculating Activity Info Values

Former Member over 9 years ago

Hello -

I would like to implement a new method of generating sport-specific cadence values on-watch. This would be based on accelerometer values that are now available (Thanks Garmin!).

What I can't determine is if it is possible to calculate and set the cadence value that gets stored in the FIT file for recording.

This is hugely important for my application as I would like to use the cadence values I calculate as opposed to those generated on the watch.

Any help is appreciated -

You can't currently inject data into the FIT file stream.

Thanks for your response, it's good to at least have clarity on this point.

A follow-up question would be - of what practical use is access to the accelerometer if this signal cannot be processed and somehow recorded? or is there another way to store data and get it off of the device that I am unaware of? I know Garmin waited a long time to get accelerometry 'right' in the SDK, but it seems this aspect would be a necessary first step to making this data truly useful for developers.

Thanks again -
