The underlying NetworkStream.

GetStream()()() returns a NetworkStream that you can use to send and receive data. The NetworkStream class inherits from the Stream class, which provides a rich collection of methods and properties used to facilitate network communications.

You must call the Connect(BluetoothEndPoint) / [M:Connect(InTheHand.Net.BluetoothAddress,System.Guid)] method first, or the GetStream()()() method will throw an InvalidOperationException. After you have obtained the NetworkStream, call the Write(array<Byte>[]()[], Int32, Int32) method to send data to the remote host. Call the Read(array<Byte>[]()[], Int32, Int32) method to receive data arriving from the remote host. Both of these methods block until the specified operation is performed. You can avoid blocking on a read operation by checking the DataAvailable property. A true value means that data has arrived from the remote host and is available for reading. In this case, Read(array<Byte>[]()[], Int32, Int32) is guaranteed to complete immediately. If the remote host has shutdown its connection, Read(array<Byte>[]()[], Int32, Int32) will immediately return with zero bytes.
