I'm developing an app for Uni which needs to show on screen a persons heart rate preferably in real time (but its not necessary) as well as the pulse oximeter results.
The app is being developed in Kotlin and the hardware used to catch this measurements is a Huawei SmartBand 4 Pro.
I already know for a fact that in order to connect to the watch to the phone i need to use the Huawei Health App otherwise it will not be recognized by the Bluetooth adapter.
But i have no idea how to start retrieving or streaming the heart rate data from the the watch to the phone.
Will the GoogleFit API suffise for this? or would i need to use the Huawei health SDK for this.
I have no guidance for this or experience developing apps that use external sensors, and will need to deliver this app starting october so any help would be appreciated
