# IOBluetoothRFCOMMChannel

An instance of this class represents an RFCOMM channel as defined by the Bluetooth SDP spec..

## Declaration

```swift
class IOBluetoothRFCOMMChannel
```

## Overview

Overview An RFCOMM channel object can be obtained by opening an RFCOMM channel in a device, or by requesting a notification when a channel is created (this is commonly used to provide services).
