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 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

This script blinks the right hex display of all nodes to ensure broadcast
communication on the network.

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 NETWORK to the IP address of your host PC NIC network (eg X.Y.Z.0 for IP X.Y.Z.W)

Description:
  This script will cause all nodes on each of the network to blink their hex
displays.  If a node has not been initialized with an IP address (ie, it has
just booted and and has not had its network configured via init_nodes()), then
it will respond to all broadcast packets that are seen regardless of the
network.  This is useful to test connectivity regardless of further network
segmentation during the experiment.
