I found this post where it says Apple watch supports CoreBluetooth WatchOS & BLE

I made this game in Unity and I need to show updated heart rate so I was wondering if it possible to connect with a Watch app that read the heart rate and send data to the app using Bluetooth.

All help appreciated.

Please note that I have tried WatchConnectivity and no luck there.

If your Watch app and iOS app are running at the same time, your Watch app can get the health data and use WatchCOnnectivity's send message function. I know you've tried WatchConnectivity, but it does work. What specifically did you try in WC that didn't work?

I have tried WatchConnectivity and it worked fine, but only in case the Watch app was a companion app basically under the same bundle identifier which I can not guarantee that the watch app will have the same bundle id as the game.
