analyze date using both nomal and sensitive settings

[xiaofang]

If I want to download the Fitbit date from the Fitbit App, How can I analyze these date using both the normal and sensitive settings, because I  read some papers, which wrote that "The proprietary software algorithms for both the Normal and Sensitive sleep-recording modes were assessed."

Hello @xiaofang and welcome to the Help forum.  I found a similar thread in the Web API Development forum, where a user is asking how to extract personal data.  I hope this will help.

I am also moving this thread to the Web API Development forum, a better fit fir this question.  That board is moderated by developers and you might get a better answer.

Recently, I read some sentence about the Fitbit Flex, The FBF was left in default (Normal) settings during the sleep recording; however, outputs for both Normal and Sensitive settings were available during off-line analyses for evaluation since the setting at the time of recording does not limit the off-line sensitivity outputs available. The FBF sleep variable data was extracted from the Fitbit web interface after the device synchronized with the interface through the Bluetooth capabilities of a USB-connected dongle. After device synchronization, the start/end points of sleep periods were manually adjusted to correspond to PSG lights-off and -on, and outputs from both Normal (FBF-N) and Sensitive (FBF-S) algorithms were obtained.
But, I did not know how to get both Normal and Sensitive date when I export the date. I just get one group date. Should I use some special software?

@xiaofang   I am merging this thread with your other thread on the same topic.  No need to post a second thread or type in all caps.

The Charge 4 forum is aimed at helping users get the most from their Charge 4.  You need help from a developer.

Hi, Recently, I read some sentence about the Fitbit charge, The device was left in default (Normal) settings during the sleep recording; however, outputs for both Normal and Sensitive settings were available during off-line analyses for evaluation since the setting at the time of recording does not limit the off-line sensitivity outputs available. The  sleep variable data was extracted from the Fitbit web interface after the device synchronized with the interface through the Bluetooth capabilities of a USB-connected dongle. After device synchronization, the start/end points of sleep periods were manually adjusted to correspond to PSG lights-off and -on, and outputs from both Normal  and Sensitive algorithms were obtained.
But, I did not know how to  export Normal and Sensitive date from the Fitbit web interface. Should I use some special software?

Hi @xiaofang 

Before analyzing the sleep data that comes through the Web APIs, I think it's important to understand how the Sleep data is analyzed today.   Here's a help article that explain the conditions for generating one of our 2 types of sleep logs: classic or stage.   See https://help.fitbit.com/articles/en_US/Help_article/2163.htm.   

At a high level, classic sleep is our 1st generation to analyze sleep data.  We output the data as asleep, restless and awake.   Today, our devices will generate classic sleep logs if we don't have enough data to generate the stage sleep logs, if you slept for less than 3 hours or your device battery is critically low.  Stage sleep is our current method for analyzing sleep data.   We out the data as light, deep, rem and wake.  I believe as long as the device supports heart rate, we will default to generating the stage sleep logs.

You can export the data through the Web APIs.   You'll need to build an application that allows you to consent to share your data with the application via OAuth2.  After consent is established, you'll use the Get Sleep Log endpoint to fetch the JSON data.  If you would you like to learn how to interpret the sleep log data, see Interpreting the Sleep Stage and Short Data.

Hello, I build an application according to the guide, but I just can not get the code.https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=23BGY6&redirect_uri=https%3A%2F...

https://dev.fitbit.com/apps/oauthinteractivetutorial?clientEncodedId=23BGCF&clientSecret=c38455c0664...

  would you please give some advice?

Hi @xiaofang ....  The URL provided is exposing your client secret.   Make sure you change that to protect your application and participants sharing their data.

Everything look correct with me when I test the authorization endpoint at the URL.   Are you getting an error?   What behavior are you observing instead of receiving the authorization code?
