# send(message:)

Sends a message to the transport extension.

```
final func send(message: AccessoryMessage) async throws
```

## Parameters

`message`

An accessory message.

## Discussion

This method conforms to [`AccessoryFeatureSession`](/documentation/AccessoryTransportExtension/AccessoryFeatureSession) but always throws [`AccessoryTransportSession.Error.unsupported`](/documentation/AccessoryTransportExtension/AccessoryTransportSession/Error/unsupported); call [`send(data:)`](/documentation/AccessoryTransportExtension/AccessoryWorker/Session/send(data:)) instead to send data to the transport extension.
