BLE Heart Rate Monitor package

This is a simple Unity package that adds wrapper above Unity Android Bluetooth Low Energy package to read heart rate data from BLE devices.

Building

Beware that Minify should be disabled, if enabled the Bluetooth capabilities won't work, so it should be disabled for the build. This is probably because the Unity Android Bluetooth Low Energy use prebuilt jar libraries that are not compatible with the minification process.

Android Manifest

1. Check that the custom AndroidManifest.xml file is enabled in Player settings.
2. Check that the AndroidManifest.xml correctly configured to include the necessary permissions for Bluetooth operations.
3. Ensure that the Application Entry Point is set to Activity and not the GameActivity (which is default in Unity 6+).
