v2 v3 7 7 = 802.11 Reference Design: TX/RX Log Capture Example = 8 8 9 This example of the Experiments Framework uses two WARP v3 nodes, one configured as an AP, the other as a STA. The two_node_dual_flow_capture.py will capture a log file of LTG traffic flows between the AP and STA and write the data to an HDF5 log file for later processing. This example demonstrates how to:9 This example of the Experiments Framework uses two WARP v3 nodes, one configured as an AP, the other as a STA. The log_capture_two_node_two_flow.py will capture a log file of LTG traffic flows between the AP and STA and write the data to an HDF5 log file for later processing. This example demonstrates how to: 10 10 * Control two WARP v3 nodes from one wlan_exp script 11 11 * Use the wlan_exp framework Local Traffic Generator (LTG) to create traffic 12 12 * Capture an HDF5 log file from the data logged by each node 13 13 14 The flow of the two_node_dual_flow_capture.py script is:14 The flow of the log_capture_two_node_two_flow.py script is: 15 15 1.
