Constructor Detail

BluetoothRFCOMMChannel

public BluetoothRFCOMMChannel(java.lang.String remoteDeviceAddress,
                              int remoteChannelNumber)
                       throws java.io.IOException

Construct a Bluetooth RFCOMM channel object with a specific remote endpoint. This does not yet open the channel, @see open needs to be called for that.

Parameters:

remoteDeviceAddress - The Bluetooth MAC address to connect to, in format "AABBCCDDEEFF".

remoteChannelNumber - The SDP RFCOMM channel number to connect to, usually between 1 and 10.

Throws:

java.io.IOException - When the local Bluetooth stack was not initialized properly.

Method Detail

open

public void open()
          throws java.io.IOException

Opens a channel to the endpoint given to the constructor.

Throws:

java.io.IOException - On Bluetooth errors.

java.io.IOException - When the channel has already been opened.

close

public void close()
           throws java.io.IOException

Closes the channel to the endpoint given to the constructor. It may be re-opened with another call to @see #open.

Throws:

java.io.IOException - On Bluetooth errors.

java.io.IOException - When the channel has not yet been opened.

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

Returns the InputStream object for reading from the remote Bluetooth device.

Returns:

The InputStream object openend in @see #open.

Throws:

java.io.IOException - When the channel has not yet been opened.

getOutputStream

public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException

Returns the OutputStream object for writing to the remote Bluetooth device.

Returns:

The OutputStream object openend in @see #open.

Throws:

java.io.IOException - When the channel has not yet been opened.

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException,
                        java.lang.NumberFormatException

Switches the state of the local device between Master and Slave

Throws:

java.io.IOException

java.lang.NumberFormatException
