I am a researcher working on measuring physiological data such as SpO2, EDA, ECG, and temperature data. We would like to use Galaxy smartwatch 3 as a monitoring device for the research. However, before buying a lot of devices, i need clear and detailed information about the accessibility of SpO2, EDA, ECG, and temperature raw data. If i need to develop a samsung watch app that read and process through custom algorithms raw data coming from these sensors, is it possible?
I just want clear and detailed information before buying a lot of devices.
Figure out that I can use Tizen studio to create a native/web app to retrieve the data.

My current is on Flutter using Dart and working with Bluetooth low energy devices. I have the basics up using this library and am able to do the following
1. Search for devices and list
2. Connect to device
3. Retrieve services and read characteristic values
4. Subscribe to changes on characteristics.
In order to interact with device correctly I need to read and write from the correct services/characteristics to read data and set things like resistance on the flywheel
I have used the below link and have started mapping out the services, however although the reading can be worked out. The writing to characteristics is a bit out of my reach.

The question is.
Does any have experience working BLE cycle trainers and could provide
some insight into how to read and manage services and characteristics
appropriately?
I have trouble finding devices from the market that send live data of heartrate via bluetooth.
Getting SDKs from big companies is a tedious task, and therefore I need just a simple device, which is possible to pair to native Android or to Unity via plugin.
Any suggestions?
All Polar products will fit your needs. I recommend the Polar H7, H10 or OH1.
Is there any way to read data continuously upon request without using notifications? Thank you for your help.
If you want an app capable of working with all the sensors from CC2541DK, CC2650STK, ThunderBoard React and Sense (e.g. accelerometer., magnetometer, gyroscope etc.), you can download it from: BLE SensorTags (blessTags) – the software is able of giving new uses (movement & magnetic security, accelerometer mouse, PC remote control and wireless presenters) to all these IoT SensorTags. For more info: Bluetooth low energy SensorTag.
Yes, it is possible. You have notifying and reading mechanism of data transfer - in CC2650 almost all characteristics support both mechanism of data transfer. But other characteristics can only be accessed based only one method of data reading. One such example is the reading of the buttons states on the CC2650STK and CC2541DK that can only be read by means of the notification mechanism. But, notifications is preferred if you need a higher data transfer rate between the SensorTag and your application.
I am looking for a fitness band which provides direct real-time sensor data over Bluetooth to a mobile (Android) app. I want to write a health app that tracks the heart rate continuously. Most of the bands I found, does not provide direct access and the sensor data needs to be synchronized over the web.
While searching I came across the “Microsoft Band”. Their website (http://developer.microsoftband.com/) says it provides data directly over Bluetooth. But I also found out that for an third party Android app to access the sensor data one has to install “Microsoft Health” app beforehand. Hence I am in doubt whether the data for the Microsoft Band also gets synchronized over the web through the Microsoft Health app or not.
Can someone please clarify my doubt, i.e. whether the sensor data can be access directly at real-time or not. I just want to be sure before buying the product.
On Android, in order to stream sensor data from the Band via the Band SDK, you must install the Microsoft Health application. However, the aggregate data collected by the Microsoft Health application and sync'd with the Cloud is completely independent of any data streamed in realtime by a third party application.
Recently I learned that the raw data from the heart rate optical sensor (what is called PPG signal) is available for Galaxy S5 devices using the new sensor extension SDK from Samsung, which means that the sensor physically outputs this data.
Since the same sensor is used in Gear watches, I'm wondering if there is any way to access this raw data from the watch's sensor.
I reviewed the Samsung developers site and different forums, but didn't find the way to do it, only to access the heart rate itself.
Will appreciate your advises.
