Acquire data from Galaxy Fit 3 without using mobile app

I would like to acquire all the data related to sleep and number of steps from the Galaxy Fit 3 device, to send them to a programmable microcontroller with BLE communication, without the need for a cellular application. Could someone help me please? So far, I have only been able to acquire Heart Rate data through a BLE scanner using my cell phone, which is data that I have been able to observe is available under the specifications of the BLE standard. I would like to be able to obtain the other data as well, could you help me please?

Hello,
As far as I know that Galaxy fit series is RTOS based. So it is not possible to read or modify anything from the Galaxy Fit from 3rd party application.

Thanks!
