Extended Environments Markup Language: EEML. Appledore Tide Times for 23rd March 2012. NETWORK OVERVIEW. This page is a overview of network types and how they specificaly relate and function using the ZIGBEE PROTOCAL and XBEE modules.
All networks come from a need to transfer somthing from one place to another, the ability to do this consistantly is how networks propagate. It is the why in the shape of roads. Swarm protocol RF communication: One of the main goals of this project was to investigate the possibilities of linking up the new mesh technologies provided by the XBEE ZIGBEE protocol and hardware with the older idea of swarm intelligence and "self" organizing systems. The technical opportunities: The new XBEE modules support a full range of low power operations linked with persistent routing tables and sleep modes.
This allows the modules to be run off of battery or intermittent power supplies while keeping the integrity of the overall network. Using a dispersed network of modules to complete a task provides some benefits and problems. Protocol greek pr? Definition communications. Www.digi.com/pdf/wp_zigbeevsdigimesh.pdf. The DigiMesh™ Networking Protocol. DigiMesh is a proprietary peer-to-peer networking topology for use in wireless end-point connectivity solutions.
The nature of its peer-to-peer architecture allows DigiMesh to be both easy to use and equipped with advanced networking features, including support for sleeping routers and dense mesh networks. Overhead associated with the protocol and data payload is optimized for network performance and addressing is made simple so you spend less time defining your network, and more time on your application. As a portable protocol, DigiMesh can be deployed in a number of wireless products servicing a broad array of applications needs, including multiple frequencies and hardware platforms. There are plans for several embedded RF module offerings, as well as ready-to-deploy non-embedded solutions including adapters, network extenders and technology gateways.
Why Use DigiMesh? Current Offering: XTend products with a firmware change (no support for sleeping routers) XBee / RF Family Features Comparison Matrix. Dolton - Main Index. Processing - xbee-api - How to use XBee-API with Processing - A Java API for Digi XBee/XBee-Pro OEM RF Modules. Processing is a powerful tool for visualizing physical computing projects.
Since both Processing and XBee-API are written in Java, it's easy to use them together. This entry describes how. update 3/2/14 Processing no long uses RXTX for serial port communication. They are now using JSSC ( This means you need to use xbee-api with Processing you'll need to install RXTX and place in Processing classpath and library path or simply use an earlier version of Processing After starting Processing, the first thing we need to do is add the XBee-API JAR files. Now copy and paste the code below into the Processing editor. The logging setup is recommended in the event things aren't working quite as planned. The setup method creates an XBee object and connects to the radio. The readPackets method will retrieve all packets that are waiting in the queue. This example doesn't include any graphics code, such as visualizing your data, but there are plenty of examples on the Processing site for help there.
Xbee-api - A Java API for Digi XBee/XBee-Pro OEM RF Modules. Overview This is a Java API for communication with XBee/XBee-Pro series 1 (802.15.4) and series 2 (ZB/ZigBee Pro) OEM RF Modules, in API mode.
The objective of this project is to provide a flexible and simple to use API to interact with XBee radios. In terms of flexibility, the goal is to not constrain you to a particular implementation (e.g. GUI, Web App, Processing etc.), but instead let you decide how to use it. This software has been tested on Windows, Mac, and Linux and can run on any other platform that supports Java 5 or greater and RXTX, including the Rasberry Pi! Note: This software requires API mode, by setting AP=2. News. DevelopersGuide - xbee-api - Developer's Guide - A Java API for Digi XBee/XBee-Pro OEM RF Modules. The XBee class is the primary interface for communicating with an XBee radio and a gateway to the wireless network.
The XBee class coordinates sending and receiving data, via packets. An instance of the XBee class is created as follows: XBee xbee = new XBee(); This software communicates with XBee radios through serial communication, so you will need to connect an XBee radio (typically a coordinator) to your computer's serial port. Since most computers don't have serial ports these days, a USB-serial adapter is a popular choice for interfacing with XBees.
The open() method must be called to establish a serial connection to the radio. Xbee.open("COM1", 9600); The COM port varies depending on the operating system: Maps Javascript API V3 Reference - Google Maps JavaScript API V3 - Google Code.
