Value in FIT file not viewed in GC

I have calculate one value of virtual power and after i have write it in the FIT file.

The power is regulary in FIT file, but when i upload file FIT in Garmin Connect the value is not present in the graphs of GC.

In Delegate module i have create session and createField:

powerFF = session.createField("Watt", 1, Fit.DATA_TYPE_UINT8, {:mesgType => Fit.MESG_TYPE_RECORD, :units => "watt"});

i the View module i have calculated value of power and after setData the value:

powerFF.setData(power.format("%0.0f"));

why not display the value of power in the graph of GC ?

thanks much

One thing I noted is you're adding your own Heart Rate. That should already be recorded in the .fit, so you may not need it.

ok. then i can remove Heart Rate.

thanks for info

Well, whether you want an integer or a float in the graph, either way the format() function will not give it to you. Format() returns a string.

If you want an integer in the graph, you could use powerFF.setData(power.toNumber())

You should also change the data type to DATA_TYPE_UINT16 or something similar. But you should decide what data type you want to record and be consistent with the field type you're declaring and what you're passing to setField().

I'm not sure why "powerFF.setData(power);" doesn't work for you, though.

Did you upload your app to the store as Jim suggested? You won't see a graph unless the FIT file was recorded from an app that was downloaded from the store.

Have you tested the app with MonkeyGraph, as explained here? https://developer.garmin.com/index.php/blog/post/connect-iq-2-the-full-circle

Even though MonkeyGraph is a little buggy, it will allow you test your FIT contributor stuff before uploading to the store. It will save you a few steps while you try to get it working initially.

the values of power are regularly in the file FIT:

but are not displayed in GC.

P.S: the values of watt are not integer..

this is the file FIT:

See my comment about testing with monkeygraph above.

Skimans over 7 years ago in reply to flowstate

ok. now i try to use Monkeygraph, but before i must learn it.

thanks for now!

It's fairly simple -- there's just one step that some people (including me) miss the first time.

1) Export app as IQ file (Export Wizard...) as if you were going to submit it to the store (but you don't have to, yet)

2) Run app in simulator so you can obtain a FIT file. (You could also run it in the watch, but this is easier)

In the sim:

- Start timer: Data Fields > Timer > Start Activity

- Simulate FIT data (if necessary): Simulation > FIT Data > Simulate Data

- Stop timer: Data Fields > Timer > Stop Activity

- Save activity (do not skip this step!): Data Fields > Timer > Save Activity

- Save FIT file: Simulation > FIT Data > Save FIT Session...

3) Run MonkeyGraph (Connect IQ > Start MonkeyGraph)

Open the IQ file and FIT file from 1) and 2).

hi Flowstate

why before you tell me that i must upload app in store of Connect IQ when i can use simulator for obtain FIT file and after proceed with point 2) and 3) ??

why is necessary to upload app in the store ?

i can proceed directly to use simulator and Monkeygraph in Eclipse...

Skimans over 7 years ago in reply to flowstate

i have create FIT (using simulator) and put on Monkeygraph with IQ file, but i dont see nothing in the graph...

in the file FIT there is not power values (i have also converted FIT file in XLS file using FitSDK..for check fine the file).
