HwTransportProvider

interface HwTransportProvider

Transport-agnostic provider for hardware device discovery and connection.

Each transport type (BLE, USB, etc.) implements this interface to handle its own scanning, connection, and disconnection semantics.

  • BLE: Active scanning via Kable, connect by advertisement/device ID

  • USB: Device enumeration via platform APIs, connect by vendor/product ID
