Method Detail

receivePacket

public IncomingData receivePacket(ConnectionID cid)
Description copied from interface: IRadioProtocolManager
Receive incoming data over a Connection ID. If the Connection ID is a server, this will be any data received on the given protocol/port: if the Connection ID specifies a counterpart, it will be data received from that counterpart. It is an error to attempt to receive data over a broadcast Connection ID. This method blocks until data is received over the given Connection ID.

Specified by:
receivePacket in interface IRadioProtocolManager
Parameters:
cid - the ConnectionID over which to receive data
Returns:
the received data

receivePacket

public IncomingData receivePacket(ConnectionID cid,
                                  long timeout)
Description copied from interface: IRadioProtocolManager
Receive incoming data over a Connection ID. If the Connection ID is a server, this will be any data received on the given protocol/port: if the Connection ID specifies a counterpart, it will be data received from that counterpart. It is an error to attempt to receive data over a broadcast Connection ID. This method blocks until data is received over the given Connection ID, or until a timouet expires.

Specified by:
receivePacket in interface IRadioProtocolManager
Parameters:
cid - the ConnectionID over which to receive data
timeout - the maximum time to block in milliseconds
Returns:
the received packet or null if a timeout occurs

packetsAvailable

public boolean packetsAvailable(ConnectionID connectionID)
Description copied from interface: IRadioProtocolManager
Answer whether one or more radio packets have been received and are queued for the given ConnectionID. It is an error to call this method for a broadcast Connection ID.

Specified by:
packetsAvailable in interface IRadioProtocolManager
Returns:
whether packets are available.

closeConnection

public void closeConnection(ConnectionID cidToClose)
Description copied from interface: IRadioProtocolManager
Deregister a handler. The ConnectionID supplied should be one that was created by a previous call to #addConnection. This call reverses the effect of the previous call.

Specified by:
closeConnection in interface IRadioProtocolManager
Parameters:
cidToClose - - the ConnectionID to deregister

addOutputConnection

public ConnectionID addOutputConnection(long macAddress,
                                        byte portNo)
Description copied from interface: IRadioProtocolManager
Register a point-to-point connection on which packets can be sent

Specified by:
addOutputConnection in interface IRadioProtocolManager
Parameters:
macAddress - - address of the other device
portNo - - port number to communicate over
Returns:
resultant ConnectionID

addConnection

protected ConnectionID addConnection(boolean canReceive,
                                     ConnectionID cid)

getConnectionState

protected com.sun.spot.peripheral.radio.ConnectionState getConnectionState(long macAddress,
                                                                           int connectionType,
                                                                           byte portNumber)

getName

protected abstract String getName()

addInputConnection

public ConnectionID addInputConnection(long macAddress,
                                       byte portNo)
Description copied from interface: IRadioProtocolManager
Register a point-to-point connection on which packets can be received

Specified by:
addInputConnection in interface IRadioProtocolManager
Parameters:
macAddress - - address of the other device
portNo - - port number to communicate over
Returns:
resultant ConnectionID
