Getting raw sensor data from a wearable

I am a newbie in this field so need some help. For one of my projects, I need to collect raw sensor data specifically accelerometer data from a wearable. Can I do it using Samsung Gear fit? I mean if I write a native service app for this, can I run it in a Gear Fit independently?
Also if I record the data in a file in the wearable device, can I access that file from Tizen studio, copy and save it? If yes then how?

If it is the 5/6 year old Gear Fit2 and Fit2 Pro it is possible, I’m not sure with the very original Gear Fit but I don’t think that is possible. If this is Galaxy Fit (the one released a couple years ago, no that is RealOS and can not be modified.

I mean if I write a native service app for this, can I run it in a Gear Fit independently?

I believe there are lots of examples on GitHub for Tizen sensors.

Also if I record the data in a file in the wearable device, can I access that file from Tizen studio, copy and save it? If yes then how?

Tizen Studio is an IDE could can connect to the watch from your computer and access data and there probably is a file reader app for this too.

Again this is for the very early Gear Fit2 and Fit2 Pro not the release a few years ago. If you don’t have a device I’d suggest you get something a bit newer like a Gear Sport, Gear S3, Galaxy Watch3 or Galaxy Watch Active2.

Were you able to collect raw sensor data? I need to do that for my project also

I believe there is documentation for this on the Tizen.org site.

To do this do I need to create a Tizen wearable .Net application? Or it must be Tizen wearable web application? Which one?

I need to get sensor data and give them to my machine learning model.

I found this example on Tizen for native applications

The difference between the Tizen Native API and the web API is the possibility to set the sampling frequency of the sensor and receive the data containing accurate information about the time of measurement. These features are certainly useful for the implementation of many complex algorithms, such as motion and gesture detection.

So it appears that if you don’t need the set the sampling frequency you can do it with the Web API. Search Tizen application developer site if you do not need that

I am completely new to Tizen. I created a template project following instruction on Create Your First Tizen Wearable Web Application | Samsung Developers

Now I am reading documentation: Device Sensors | Tizen Docs where should I define variables and paste codes in this page?
should I put it in app.js file?
