# handleAccessorySensorMessage(_:)

Called when a `TransportMessage` arrives from the accessory’s
transport extension on the inbound channel.

```
func handleAccessorySensorMessage(_ message: TransportMessage)
```

## Parameters

`message`

The transport-layer message as delivered by
`DeviceAccess`.

## Discussion

Use this to receive control-plane payloads from your
`AccessoryTransportExtension` (e.g. configuration acknowledgements,
vendor-specific messages). For raw IMU sample delivery, the
extension should call `Session.sendDataToAudioExtension(_:)` directly.
