XBee Shield to XBee Shield Communication

After hours of slaving over boring and confusing data sheets at digi.com and hours of tinkering with annoying chat programs and "AT" commands, I finally got 2 XBee Shields to communicate with each other!

Parts:



I will now go through the painful preliminary steps I did to setup my xbee network.
  1. Download X-CTU from Digi's website (And installed it... yeah, I installed the updates)
  2. Repeat for both computers
  3. Put both Arduinos in Reset
  4. Attach the XBee Shield to the Arduino
  5. Attach a USB cable from one arduino to Computer "A"
  6. Attach the other USB cable to the other arduino and Computer "B"
  7. Open X-CTU on Computer A
  8. Go to the "Modem Configuration" tab... set the Modem: XBEE to "XB24-B" AND set the Function Set to "ZNET 2.5 ROUTER/END DEVICE AT"
  9. Next is the Networking and Addressing Parameters...
  10. PAN ID = 1111
  11. Scan Channels = 15 (not sure if this is even needed)
  12. Channel Verification = 0 (also not sure if this is even needed)
  13. Destination Address High = 13A200 (I found this out by typing "AT" commands into a terminal program... first type in "+++" the xbee will return an "OK" you are now in command mode... if you type "ATSH" then "" (enter), the xbee will give you it's own high address (source address) )
  14. Destination Address Low = 403E2502 (I found this out by typing "AT" commands into a terminal program)
  15. Broadcast Radius = 0
  16. Click the "Write" button on the Modem Configuration tab and wait for the XBee to program
  17. If some funny error comes up... click the button on the xbee shield and try to program it again
  18. Go to the "Modem Configuration" tab on computer B... set the Modem: XBEE to "XB24-B" AND set the Function Set to "ZNET 2.5 COORDINATOR AT"

  19. Next is the Networking and Addressing Parameters for the XBee attached to computer B...
  20. PAN ID = 1111
  21. Scan Channels = 15 (not sure if this is even needed)
  22. Channel Verification = 0 (also not sure if this is even needed)
  23. Destination Address High = 13A200 (I found this out by typing "AT" commands into a terminal program... first type in "+++" the xbee will return an "OK" you are now in command mode... if you type "ATSH" then "" (enter), the xbee will give you it's own high address (source address) )
  24. Destination Address Low = 404A4FC4 (I found this out by typing "AT" commands into a terminal program)
  25. Broadcast Radius = 0
  26. Click the "Write" button on the Modem Configuration tab and wait for the XBee to program
  27. If some funny error comes up... click the button on the xbee shield and try to program it again
  28. whew... now both devices are configured properly... open the X-CTU terminal tab of each computer... type and see the characters fly from pc to pc
I would like to thank the help of the following people...
The Digi Corporation: X-CTU, XBee Data Sheet, Gilbert (866) 765-9885 (thanks for calling back and sorry I missed your call)
The Arduino XBee Page, the Arduino Forum (Thanks Brad B).
Thanks Carin from Humboldt
Thanks Limor... for your tutorial... Gilbert just posted on the Arduino forum and your tutorial seems solid!
I can't wait to actually use these for projects now.
