info.currentPower

Hi,

I have developped a datafield that display "info.currentPower". Using the similator with fr935, I can see data being populated. However, I've got a complaint from a user telling me that the field does not display values on a its physical fr935 watch. I've asked him to send me its fit file. After converting the file to a csv using FIT SDK, I can read multiple "RP_Power" data, like those :

RP_Power 83 W
RP_Power 256 W
RP_Power 250 W
RP_Power 289 W
RP_Power 280 W
RP_Power 294 W

However, if I read the fit file using the simulator, info.currentPower is always null.
Would anyone know what I am doing wrong?

Note : Not sure if it makes any difference, but the user told me he has an external Garmin running dynamics pod connected via ant+.

Thanks!

Garmin has CIQ run power DFs that works with the RD pod or HRM-Tri, but those values aren't available to other CIQ DFs.

But the Garmin RP DFs do write info to the fit file.

Um.

Correct me if I'm barking up the wrong tree, so to speak, but isn't running dynamics pod for cadence and ... er ... running dynamics?

Don't think that has power at all.

For power, surely you need a power meter?

Thanks jim_m_58,

Does it mean info.currentPower is available only if no pod or HRM-Tri are connected? If connected,.power data is retrieved using an another technique (using ANT API I would guess). Is that how this work?

For running power, it's calculated by the Garmin DF. What it uses and how it's calculated is something I doubt Garmin will say.

I think currentPower is only for a bike power meter, where it's easy for the FW to get it from the sensor.

Jim you are correct, the currentPower is only for a bike power meter and shows the value of the current sensor. You will only get that reading if you have a power meter connected to your device.
