Detailed Description

The Dexter Industries NXTBee sensor brings the Digi XBee radios to the Lego Mindstorms NXT system! These high-speed long-distance wireless communications sensors allow your NXT to communicate with any other device with an XBee radio. The XBee 802.15 communication protocol is the standard for robots everywhere!

Communicate Far: With the NXTBee you can send information up to 300 ft and the NXTBee PRO up to 1.2 km.

Communicate Fast: The NXTBee utilizes the high speed RS-485 line for high speed communication.

Communicate Wide: The NXTBee uses the XBee protocol which includes point to point networking and mesh networking.

A very useful package for RobotC from Tim Frietz at CMU. A very easy way to start and send data and includes a short cheat sheet on RobotC functions for use with the NXTBee.


Configure NXTBee


A very useful NXTBee utility built by Xander. This program configures a fresh Xbee radio for use with the NXTBee system. This program allows you to test, set, and reset the baud speed. Thanks Mightor!
