= 802.11 Reference Design: Blink Node LEDs Example = 

This example of the Experiments Framework is very simple. It uses a simple Python script to send a broadcast command to all WARP v3 nodes which causes them to blink the hex dispaly LEDs for 5 seconds. This script is a good way to test your Python installation, PC network configuration, nodes configuration and Ethernet connections. 

'''Source:''' the script is included in the 802.11 Reference Design archive at '''Python_Reference/examples/blink_node_leds.py'''.

To run this example:
 * Setup wlan_exp (see [wiki:../../GettingStarted Getting Started] for details)
 * Configure your WARP v3 nodes with the 802.11 Reference Design bitstream (AP or STA)
 * Open a Python shell
 * CD to the '''Python_Reference/Examples''' directory from the expanded 802.11 Reference design archive
 * Run {{{python blink_node_leds.py}}}
