+= 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 '''Python_Reference''' folder of the 802.11 Reference Design archive. The latest version of the code is also displayed below.
+
+To run the script:
+ * Open a Python shell
+ * CD to the '''Python_Reference/Examples''' directory
+ * Run {{{python blink_node_leds.py}}}
+

+This script blinks the red LEDs of all nodes to ensure broadcast communication
+
+Hardware Setup:
+ - Requires one or more WARP v3 nodes configured with the 802.11 Reference
+   Design v0.81 or later.
+ - PC NIC and ETH B on WARP v3 nodes connected to common gigbit Ethernet switch
+
+Required Script Changes:
+  - Set HOST_INTERFACES to the IP address of your host PC NIC
+
+Description:
+  This script will cause all nodes on each of the host interfaces to 
+blink their LEDs.
