    Xbee-Api download site:
    http://code.google.com/p/xbee-api/downloads/list

    I used this page to get going with the xbee-api in eclipse:
    http://code.google.com/p/xbee-api/wiki/GettingStartedWithEclipse

    Then I set up the xbees in the exact way that the xbee-api website instructed.
    http://code.google.com/p/xbee-api/wiki/XBeeConfiguration

    At first I was getting strange errors and I then found out that my txrx jar and dll were meant for a 32 bit os. So I downloaded the necessary 64 bit libraries here:
    http://jlog.org/rxtx-win.html

    I was then able to turn on an led wired to the remote xbee by running the RemoteAtExample.java included in the api.

    I then put this code into a max mxj object and was able to flash the light remotely from.

    To get this to work in max I did the following:
    - In the root max directory I placed the 32 bit rxtxSerial.dll
    - In \Max 5.0\Cycling '74\java\lib I placed log4j.jar, xbee-api-0.9.jar, and the 32 bit RXTXcomm.jar

    Maxbee.java - Source
    Maxbee.class - Put this in your Max class path

    Below are patches for two way communication with x-bees from Cycling '74's Max.
    You must have your local (usb/API-coordinator) and remote (wireless/AT-router/endpoint) Series 2.5 Xbees configured with these profiles.  

    max files: download
    profiles:  download

    Notes:
    -xbee.js takes in two arguments. The remote xbee's 8 byte address and the 2 byte network address. 
    -This whole setup only works if you have 4 analog pins active, and nothings else
    -Note that if you turn digital pins on/off, this messages with the analog readings; this will be fixed in the next version!

    Secret+Critical Knolwedge:
    -When trying to configure a coordinator connected with USB, the remote xbee's can not send too much data (set sampling rates to very low or 0)
    -After remote-configuration of a router xbee, you must quit/restart X-CTU before configuring a USB-connected-coordinator xbee

So far I have the ability to change the function of different xbee pins by calling a method in a little piece of javascript. I will post... kamp0145
    I also worked some with the accelerometer today. I am working on a max patch that takes the accelerometer readings from the xbee and makes a nice little visual display tilt sensing.

    Remote API commands are working perfectly!

    and now for range testing...

    The xbee is hard wired to my computer using a sparkfun xbee explorer. It is running the XBP24-B ZNET 2.5 ROUTER/END DEVICE API version 1247 firmware.

    Using a max patch I sent the following converted the following hex message into decimal values and sent it through serial. 
        0x7E 0x00 0x05 0x08 0x4D 0x44 0x30 0x05 0x31

    0x7E = start delimiter 
    0x0005 = length
    0x08 = AT Command API frame type
    0x4D = Frame ID (set to non-zero value) (any value)
    0x4430 = AT Command ('D0')
    0x05 = value to set command to (pin HIGH output)
    0x31 = Checksum

    To calculate the checksum: Not including frame delimiters and length, add all bytes keeping only the lowest 8 bits of the result and subtract the result from 0xFF.


    This command turns the digital output of pin D0 to HIGH.

    This command turns output of pin D0 to LOW:
       0x7E 0x00 0x05 0x08 0x4D 0x44 0x30 0x04 0x32

    Despite the poor documentation of this experiment, I tried to recreate it. 
    Recreation was unsuccessful...

    Something good that came out of this experiment is that I found an Xbee API for Processing which could come in handy later. http://www.faludi.com/code/xbee-api-library-for-processing/

    A lot of instructions that I came across today asked me to press the reset button on the xbee. Because we have no reset buttons on the xbee, I have found two alternatives. 
    1. Short ground(pin 10) and reset(pin 5)
    2. Or unplug the xbee from the explorer, select a command to execute, and then plug the xbee back into the explorer.

    In every analog test that I have run I have used the following photo-resistor circuit.
    http://www.lizarum.com/assignments/physical_computing/images/xbee/analog/sender_bb.png

    In the example at the top of this post, they ask you to change a value with the command ATIT. This returns ERROR when entered on the current firmware that is running on the "sender" xbee. I will pursue these analog tests using a different xbee firmware that may have more promising Analog features.

    Using the XBee Pro series 2 (XBP24-B) The ones without the antennae:

    -Plug Xbee into the bottom USB port
    -Open X-CTU
    -Under "PC Settings > Com Port Setup > Select Com Port" choose USB Serial Port
    -To make sure the XBee is working choose "Modem Configuration > Modem Parameters and Firmware > Read"
    -If a screen titled "Info" pops up, unplug the XBEE FROM THE BREAKOUT BOARD. DO NOT unplug the breakout board from the USB port
    -The screen should go away within 10 seconds (you may have to do this more than once)
    -The current firmware should be loaded onto the screen

    For a Coordinator:
    -Under "Modem Configuration > Modem" choose XB24-B and under "Function Set" choose ZNET 2.5 COORDINATOR AT
    -Click on "Addressing > NI - Node Identifier" and then "Set"
    -Type in "COORDINATOR" and click "Ok"
    -Choose "Modem Configuration > Modem Parameters and Firmware > Write"
    -If a screen titled "Info" pops up, unplug the XBEE FROM THE BREAKOUT BOARD. DO NOT unplug the breakout board from the USB port
    -The screen should go away within 10 seconds (you may have to do this more than once)
    -If the firmware is loaded correctly, there should be a line that says "Write Parameters...Complete" near the bottom of the screen
    -Switch to the "Terminal" tab
    -Unplug the USB cord from the computer
    -Plug the cord back in
    -Choose "Terminal > Close Com Port" and then "Terminal > Open Com Port"  (same button)
    -DONE!

    For a Router/End Device:
