Samsung Galaxy Watch3 BLE connection

Dear all

I have a Samsung Galaxy Watch3. I've developed an Android application for my smartphone, in order to be able to access the internal sensors of the Watch3 through BLE connection (I need the raw data of these sensors, mainly the GPS, the Heart Rate and the Pedometer). Up to now we have succeed to connect and to communicate with the device through BLE and the following Service UUID: 00001800-0000-1000-8000-00805f9b34fb and Charactristic UUID: 00002a00-0000-1000-8000-00805f9b34fb (or alternatively with the Charactristic UUID: 00002a01-0000-1000-8000-00805f9b34fb). In these UUIDs the devise returns some numbers (7 and 97 correspondingly) which we cannot yet interpret their meaning. My question is the following: Can we access the sensors of interest i.e. the GPS, the Heart Rate and the Pedometer of Watch3 and if yes, what are the corresponding Service UUID and Characteristic UUIDs? 

Thank you in advance
