Best way to programming this app?

I wouldn't count on it, as its not on the phone that long.  If there's no internet connection of the phone, it won't even sync the .fit to the phone.

The devices are synced by BT, I suppose if there is not connection, the .fit file will be stored in the watch and synced on next time the devices get connection. 

Do you know how long the file is stored in the phone? Or if it can be find programmatically from Android app? 

Hi again!

I have been checking the Pitch Counter example and i have simulate data in the CIQ simulator. When i have save the session and open the data on Subime, i have seen that the .fit file is not plain text.

0486 0304 8602 0284 0502 8406 0284 0702
....

Any idea of how i can decrypt this data?

Thanks!

See the FIT SDK: https://www.thisisant.com/resources/fit/

This SDK is to use in Eclipse with ANT?

I would need to use it in Android Studio. My aim is to decode the .Fit file in a mobile app or to find the best way to send the watch sensor data to the mobile without lose data. 

The fit sdk defines how you can read a fit file and get it's content.

Hi Travis!

For the session example you pasted me above, wich kind of app did you use? I am wondering about which is the best place in the app to start the session, becouse in the pitch counter sample, the session appears in a class called process, which is called from the view. But in your first example (get low and high frecuency data) you have a Behaviour Delegate.

Hi Again!

I have finally programmed the app based on the PitchCounter example, using the session object. I am running it from the CIQ Simulator. And simulating data from Simulation/Fit Data/SImulate Data. 

As you can see in the picture below, i am correctly getting data and printing in te console. In this case is accelerometre X axis data and Hearth rate beat intervals every second.

When i stop the simulation and i save the session from simulator (Simulation/FIT Data/Save FIT Session), i get a .FIT file, but this file has not the data i am trying to record in it (accelerometer and Heart Rate). When i open it, i see the next:

I get dummy data from latitude, longitude, altitude, distance, speed, grade and timestamp. But the accelerometer and heart rate data has not be recorded. Why this is happening?

If i analize the code, i am not saying specifically to save accelerometer and hearth rate data on the file when a new sample arrives. I paste my code to see if you can check it and do you find any error.

I am also having issues with the Logger objet, when i execute the next code lines i do not recive anything.

mLogger.getStats().sampleCount;
mLogger.getStats().samplePeriod;

Hope you can help me.

Have you tested with the pitch counter sample to verify that you can see the data in the FIT file? I'd start there. If it works with that app, then you've done something wrong and we'll have to isolate it. If you don't see the data, then maybe we need to figure out why.

Hi, i did the same that i explained on this answear with both examples, PitchCounter and my app. And this is what i see. What i mean is that the data does not have sense to me.

hope you can help me
