Platform frameworks

CoreBluetooth and Swift Charts are Apple system frameworks. Android Bluetooth and graphics APIs are Android platform frameworks. They are not third-party Bluetooth or distance-estimation engines.

No external ranging engine is used. Signal filtering and categorical trend logic are product-owned and do not estimate exact distance or direction.
