jmri.jmrix.ieee802154.IEEE802154Node

jmri.jmrix.ieee802154.serialdriver.SerialNode

public class SerialNode
extends IEEE802154Node

Implementation of a Serial Node for IEEE 802.15.4 networks.

Integrated with SerialTrafficController.

Each node has 3 addresses associated with it:

1. A 16 bit PAN (Personal Area Network) ID assigned by the user
2. A 16 bit User Assigned Address
3. A 64 bit Globally Unique ID assigned by the manufacturer

All nodes in a given network must have the same PAN ID

Constructor Detail

SerialNode

public SerialNode()

Creates a new instance of AbstractNode

SerialNode

public SerialNode(byte[] pan,
                  byte[] user,
                  byte[] global)

Method Detail

createInitPacket

public AbstractMRMessage createInitPacket()

Create the needed Initialization packet (AbstractMRMessage) for this node. Returns null if not needed.

Specified by:

createInitPacket in class IEEE802154Node

Returns:

the packet, or 'null' if not needed

createOutPacket

public AbstractMRMessage createOutPacket()

Create an Transmit packet (AbstractMRMessage) to send current state

Specified by:

createOutPacket in class IEEE802154Node

Returns:

packet to send current node state.

getSensorsActive

public boolean getSensorsActive()

Are there sensors present, and hence this node will need to be polled? Note: returns 'true' if at least one sensor is active for this node

Specified by:

getSensorsActive in class IEEE802154Node

Returns:

'true' if at least one sensor is active for this node

handleTimeout

public boolean handleTimeout(AbstractMRMessage m,
                             AbstractMRListener l)

Deal with a timeout in the transmission controller.

Specified by:

handleTimeout in class IEEE802154Node

Parameters:

m - message that didn't receive a reply

l - listener that sent the message

Returns:

true if initialization required

resetTimeout

public void resetTimeout(AbstractMRMessage m)

A reply was received, so there was not timeout, do any needed processing.

Specified by:

resetTimeout in class IEEE802154Node

Parameters:

m - message received that has reset the timeout and is waiting to be handled
