The eZ430-RF2500 board comes with demo software, which creates a WSN in a star topology around the Access Point . A node which is not an access point is called an End Device . By running this demo, you will learn how to use the IAR tool.

Running the code

  • Locate the folder containing the source code of the Sensor Monitor Demo, which was created when you followed the installation instructions Alternatively, this code is available in the downloadable source code , in the ti_demo folder. .
