Details about xbee...any hlp
-
Xbee is a wireless system that can be implemented almost anywhere. Here it is used as a method of communicating to other controllers or to a computer, or whatever you need your device/project to connect to wirelessly.

Someone doesn't like to google...

xbee is not zigbee
excellent tutorial on zigbee:

yeah zigbee is the other name for the IEEE 802.15.4 protocol. Whereas Xbee is a system/device, manufactured by Digi international that implements the zigbee protocol on its hardware.

Not really, ZigBee is addition layers of protocol that uses the 802.15.4 Mac and physical layers.
Digi Int has Xbee's that run 802.15.4 and ZigBee but they will not communicate with each other. There are also a few other protocols that Digi Int has for XBee modules such as DigiMesh.
The protocol is determined by the firmware loaded into a module and the chip set used in the module (series 1 or 2).
Which protocol to use is determined by what you need. For simple point to point (robot to/from PC) the 802.15.4 works well. If you have several robots that need to 'talk' to each other as well as a PC then the ZigBee protocol or DigiMesh may be better.
Digi Int has lots of documents and a good forum on their web site. Just beware that all the information is there but is written for professionals that understand more than just the basics of radio networking. That is one reason there is much confusion as to what an Xbee is and can do.
Once the protocol is understood, Xbee modules are great 'easy' to use bi-directional RF links. My next bot will be using an Xbee.

The new Xbee's can do mesh networks (outside of digimesh), but i haven't tried that mode. I have two 900 pros and love them.

Thanks waltr!
