The Procedure of Sending and Receiving Pack On Sun SPOT

The timestamp is the system time when the packet was read in from the radio chip on receives and when the packet was sent on transmits. If you consider all the steps involved in transmitting & receiving a packet things will (hopefully) become clear:

on sending spot:

1. user app packs data to send into a radiogram packet.
2. user app initiates send of packet
3. radio stack checks for route to destination, etc.
4. finally ready to send so write data to radio chip
5. data written, wait for transmission to start
6. record time packet was actually sent
7. user app can now query when transmission occurred

on receiving spot:

1. user app blocks waiting to receive a radiogram
2. radio stack receive thread blocks waiting for interrupt
3. radio receives incoming packet and stores it in fifo buffer
4. Squawk VM responds to radio interrupt and restarts receive thread
5. receive thread reads in radiogram packet from radio's fifo buffer
6. record the current time to mark when packet was received
7. radio stack processes packet and passes it to user app
8. user app does whatever it needs to with packet

As you can see from the many steps a fair amount of time can pass between when a packet is physically received & when the user program finally gets handed the packet (& ditto when sending). The timestamp on the packet is a way to minimize some of this latency.

For most applications the latency doesn't matter, but it's essential for anyone who wants to do a time synchronization protocol in order to have the clocks on several spots all be within a few milliseconds of each other.

Simple JAXP Application

The Java API for XML Processing, or JAXP (pronounced jaks-p), is one of the Java XML programming APIs. It provides the capability of validating and parsing XML documents. The three basic parsing interfaces are:

    * the Document Object Model parsing interface or DOM interface
    * the Simple API for XML parsing interface or SAX interface
    * the Streaming API for XML or StAX interface (added in JDK 6; separate jar available for JDK 5)

--http://en.wikipedia.org/wiki/Java_API_for_XML_Processing

This tutorial is based on http://www.vogella.de/articles/JavaXML/article.html

We have two XML files to read in this example. They are:

config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <mode>1</mode>
  <unit>900</unit>
  <current>1</current>
  <interactive>1</interactive>
</config>




person.xml



<?xml version="1.0" encoding="UTF-8"?>
<people>
	<person>
		<firstname>Lars</firstname>
		<lastname>Vogel</lastname>
		<city>Heidelberg</city>
	</person>

	<person>
		<firstname>Jim</firstname>
		<lastname>Knopf</lastname>
		<city>Heidelberg</city>
	</person>

	<person>
		<firstname>Lars</firstname>
		<lastname>Strangelastname</lastname>
		<city>London</city>
	</person>

	<person>
		<firstname>Landerman</firstname>
		<lastname>Petrelli</lastname>
		<city>Somewhere</city>
	</person>

	<person>
		<firstname>Lars</firstname>
		<lastname>Tim</lastname>
		<city>SomewhereElse</city>
	</person>

</people>

Simple JAXB Application

Java Architecture for XML Binding (JAXB) allows Java developers to map Java classes to XML representations. JAXB provides two main features: the ability to marshal Java objects into XML and the inverse, i.e. to unmarshal XML back into Java objects. In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a specific set of XML loading and saving routines for the program's class structure.

JAXB is particularly useful when the specification is complex and changing. In such a case, regularly changing the XML Schema definitions to keep them synchronised with the Java definitions can be time consuming and error prone.

The tool "xjc" can be used to convert XML Schema and other schema file types (as of Java 1.6, RELAX NG and XML DTDs are supported experimentally) to class representations. Classes are marked up using annotations from javax.xml.bind.annotation.* namespace, for example, @XmlRootElement and @XmlElement. XML list sequences are represented by attributes of type java.util.List. Marshallers and Unmarshallers are created through an instance of JAXBContext.

In addition, JAXB includes a "schemagen" tool which can essentially perform the inverse of "xjc", creating an XML Schema from a set of annotated classes.

--http://en.wikipedia.org/wiki/JAXB

country.xsd

<xs:schema
  xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="country" type="Country"/>
    <xs:complexType name="Country">
        <xs:sequence>
            <xs:element name="name" type="xs:string"/>
            <xs:element name="population" type="xs:decimal"/>
        </xs:sequence>
    </xs:complexType>
</xs:schema>




country.xml


<country
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="country.xsd">
    <name>France</name>
    <population>60144000</population>
</country>




1. Download JAXB from https://jaxb.dev.java.net/


2. Convert XML schema to Java class source file. The command is xjc.bat -package.name sourceXMLSchema.xsd. For example, execute xjc.bat –countries country.xsd, we should get these files:



  • Country.java


  • ObjectFactory.java



3. Create a project in Netbeans, and copy the generated source files to the folder of project source. And do not forget to add the JAXB 2.1 library in project properties.


4. Here below is the source code of main java which shows both read and write XML functions:

This is another example which is a bit complex than the one above. We have XML Schema file and a XML file.

Identify the COM port number and device address of Sun SPOT

Basically, I am using the spotfinder.exe which is a tool provided with Sun SPOT SDK to detect the COM port in use and device adddress of the connected Sun SPOT.
NOTE: Only one SPOT can be detected in this, I would like to change it later.

2. Beware of the red text area, it contains key information we need to execute Sun SPOT host side application without ANT. What we need to do is re-construct the parameters to a command. Finally, We get:
