The bt-hci-virtual driver is a Bluetooth controller emulator that allows system Bluetooth components to be tested in integration against the Bluetooth HCI procotol.

bt-hci-virtual provides aa method to add virtual HCI controllers to the system which can either be emulated, or loopback the HCI commands to a component.

It accomplishes this by publishing three distinct devices:

• A device of class “bt-emulator”. This device allows the emulator's behavior to be configured using the fuchsia.bluetooth.test.HciEmulator protocol (also see fuchsia.hardware.bluetooth.Emulator).
• A device of class “bt-loopback”. See fuchsia.bluetooth.test.Loopback.

Usage
