public class BluetoothConnectionInsecure : BluetoothConnection

The BluetoothConnectionInsecure type exposes the following members.

Constructors
  NameDescription

Properties
  NameDescription
Public propertyConnected
Returns true if the connection is open.
(Inherited from ConnectionA.)
Public propertyFriendlyName
Gets the friendly name of the Bluetooth® connection. 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.
(Inherited from BluetoothConnection.)
Public propertyMACAddress
Gets the MAC address which was passed into the constructor. The MAC address is a hexadecimal string with separators between the octets (e.g. 00:11:BB:DD:55:FF).
(Inherited from BluetoothConnection.)
Public propertyManufacturer
See the classes which implement this property for the format of the printer manufacturer string.
(Inherited from ConnectionA.)
Public propertyMaxDataToWrite
Gets or sets the maximum number of bytes to write at one time
(Inherited from ConnectionA.)
Public propertyMaxTimeoutForRead
Gets or sets the maximum time, in milliseconds, to wait for any data to be received.
(Inherited from ConnectionA.)
Public propertySimpleConnectionName
Gets the MAC address and the friendly name as the description.
(Inherited from BluetoothConnection.)
Public propertyTimeToWaitForMoreData
Gets or sets the maximum time, in milliseconds, to wait in-between reads after the initial read.
(Inherited from ConnectionA.)

Methods
  NameDescription
Public methodAddWriteLogStream
Sets the stream to log the write data to.
(Inherited from ConnectionA.)
Public methodBytesAvailable
Returns an estimate of the number of bytes that can be read from this connection without blocking.
(Inherited from BluetoothConnection.)
Public methodClose
Closes the Bluetooth® connection.
(Inherited from BluetoothConnection.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodGetConnectionReestablisher
Returns a ConnectionReestablisher which allows for easy recreation of a connection which may have been closed.
(Inherited from BluetoothConnection.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodOpen
Opens a Bluetooth® connection as specified in the constructor.
(Inherited from BluetoothConnection.)
Public methodRead
Reads all the available data from the connection. This call is non-blocking.
(Inherited from ConnectionA.)
Public methodRead(Int32)
Reads maxBytesToRead of the available data from the connection.
(Inherited from BluetoothConnection.)
Public methodRead(BinaryWriter)
Reads all the available data from the connection.
(Inherited from ConnectionA.)
Public methodRead(Int32, Boolean)
Reads maxBytesToRead of the available data from the connection.
(Inherited from ConnectionA.)
Public methodReadChar
Reads the next byte of data from the connection.
(Inherited from BluetoothConnection.)
Public methodSendAndWaitForResponse(Byte, Int32, Int32, String)
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.)
Public methodSendAndWaitForResponse(BinaryWriter, BinaryReader, Int32, Int32, String)
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.)
Public methodSendAndWaitForValidResponse(Byte, Int32, Int32, ResponseValidator)
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.)
Public methodSendAndWaitForValidResponse(BinaryWriter, BinaryReader, Int32, Int32, ResponseValidator)
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.)
Public methodSetReadTimeout
Sets the underlying read timeout value.
(Inherited from ConnectionA.)
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.
(Inherited from BluetoothConnection.)
Public methodWaitForData
Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of maxTimeout milliseconds.
(Inherited from ConnectionA.)
Public methodWrite(Byte)
Writes data.Length bytes from the specified byte array to this output stream.
(Inherited from ConnectionA.)
Public methodWrite(BinaryReader)
Writes all available bytes from the data source to this output stream.
(Inherited from ConnectionA.)
Public methodWrite(Byte, Int32, Int32)
Writes length bytes from data starting at offset.
(Inherited from ConnectionA.)
