After building this setup we got a blinking led on the GPS module, a couple of led's on the ardupilot and finally blinking green led on the sending XBee module. Unfortunately we get no data from the Xbee whatsoever. The red led is not giving any sign of data. An 'ATND' (Node detect) on the PC side gives back the ardupilot XBee and the red led is on for a second or two. We used the EM406 GPS and our XBee's are on 57600kbs. We also varied the TX and RX on the ardupilot for straightthrough GPS data, but did not work. What could be wrong here?

Remi,

Have you tried removing the Xbee module from the Ardupilot and talking to it directly with your PC to ensure that it is working correctly?
In some cases the Ardupilot can corrupt the Xbee firmware on power up if the Xbee is powered and connected to the Ardupilot serial line at the time of power up.

Thomas,

We sent an ATND command from the PC-Xbee and the Ardupilot-Xbee replied so I guess that is not an issue. Does the ardupilot come with firmware already on it? And does this firmware (we got it only a week or so, so pretty recent versions I assume) allow for the GPS data forwarding via Xbee?

Cheers, R.
Remi,

The Ardupilot board will only execute whatever version of the Ardupilot software that you have loaded on it.

The Xbee baud rate needs to be the same as the GPS since they both share the same serial line on the Ardupilot board.

Hi DIY Drones Members,

Having difficulties with installing Digi's XCTU utilitiy drivers for setting up wireless xbee telemetry. Downloaded and unzipped the file. Do not know to install the files/drivers. Have all recommended hardware(two xbee pro module's, sparkfun usb adapt., and adufriut adapt.) with Vista O.S. Have ArduStation w/ V12 code loaded, ArduPilot w/ V2.4, and ArduPilot Shield V2. Thank you for any guidance you may offer.

Used the "device manager" to change baud rates of Xbee's to match GPS. If I have ArduStation w/ Xbee connected and "on", then power up ArduPilot w/ Xbee connected the RSS led at the ArduStation lights up but no values are displayed.
Maynard,

I believe that you need X-CTU to be able to change the baud rate of the Xbees.

I have always used X-CTU and either the Sparkfun USB adapter or FTDI cable to communicate with and program the Xbees with my PC.

I am unable to install X-CTU. Have downloaded zip file from Digi site and then unzipped to file named "WINDOWS drivers". Within this file there is 22 files with these extensions ( .DOC, .PDF, .VXD, .CAT, .INF, .INI, .SYS, .VXD, .DLL, .TXT, .sys, .dll) there is only one .EXE file which is to uninstall. I tried clicking on each file and it says I need program to open the file extention. Do you know how to install X-CTU?

Regards,
Maynard
Maynard,

Try this link:www.digi.com/support/productdetl.jsp?pid=3352&osvid=57&s=31...

Also, make sure that you have the drivers installed for your PC to USB adapter.

Thomas,

That was the part I was missing. Originally did not download that file because the description says "Compatible with Windows 2000, XP, 2003 only". My system uses Vista, but I followed your link and installed the program and now have X-CTU program open. Thank you very much for your help.

Regards,
Maynard
