Methods
 NameDescription
Public methodAddWriteLogStream Sets the stream to log the write data to.
(Inherited from MultichannelConnection)
Public methodBytesAvailable Returns an estimate of the number of bytes that can be read from this connection without blocking.
(Inherited from MultichannelConnection)
Public methodClose Closes both the printing and status channels of this MultichannelConnection.
(Overrides MultichannelConnectionClose)
Public methodClosePrintingChannel Closes the printing channel of this MultichannelConnection.
(Inherited from MultichannelConnection)
Public methodCloseStatusChannel Closes the status channel of this MultichannelConnection.
(Inherited from MultichannelConnection)
Public methodEquals
(Inherited from Object)
Public methodGetConnectionReestablisher Returns a ConnectionReestablisher which allows for easy recreation of a connection which may have been closed.
(Inherited from MultichannelConnection)
Public methodGetHashCode
(Inherited from Object)
Public methodGetType
(Inherited from Object)
Public methodOpen Opens both the printing and status channel of this Multichannel connection.
(Overrides MultichannelConnectionOpen)
Public methodOpenPrintingChannel Opens the printing channel of this Multichannel connection.
(Inherited from MultichannelConnection)
Public methodOpenStatusChannel Opens the status channel of this Multichannel connection.
(Inherited from MultichannelConnection)
Public methodRead Reads all the available data from the connection. This call is non-blocking.
(Inherited from MultichannelConnection)
Public methodRead(BinaryWriter) Reads all the available data from the connection.
(Inherited from MultichannelConnection)
Public methodReadChar Reads the next byte of data from the connection.
(Inherited from MultichannelConnection)
Public methodSendAndWaitForResponse(Byte, Int32, Int32, String) Sends dataToSend and returns the response data.
(Inherited from MultichannelConnection)
Public methodSendAndWaitForResponse(BinaryWriter, BinaryReader, Int32, Int32, String) Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from MultichannelConnection)
Public methodSendAndWaitForValidResponse(Byte, Int32, Int32, ResponseValidator) Sends dataToSend and returns the response data.
(Inherited from MultichannelConnection)
Public methodSendAndWaitForValidResponse(BinaryWriter, BinaryReader, Int32, Int32, ResponseValidator) Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from MultichannelConnection)
Public methodToString The friendly name is obtained from the device when this connection is opened. If the friendly name changes on the device, it will not be refreshed until the connection is closed and reopened.
(Overrides ObjectToString)
Public methodWaitForData Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of maxTimeout milliseconds.
(Inherited from MultichannelConnection)
Public methodWrite(BinaryReader) Writes all available bytes from the data source to this output stream.
(Inherited from MultichannelConnection)
Public methodWrite(Byte) Writes data.Length bytes from the specified byte array to this output stream.
(Inherited from MultichannelConnection)
Public methodWrite(Byte, Int32, Int32) Writes length bytes from data starting at offset.
(Inherited from MultichannelConnection)

Remarks
In order to connect to a device with Bluetooth®, the device must be discoverable, authentication must be enabled, and the authentication pin must be set(1-16 alphanumeric characters).
The encryption type and whether or not it is used is determined by the device initiating the connection and not device being connected to.
