Hello,
I have a question when I use the Matlab to display the rx_pwr with rx_timestampe. The data is extracted from the log file. Only let the AP send the data to STA and STA can send ACK to AP. I keep moving the ap at a slow speed when executing the experiment. As can be seen in the figure, the data are not continuous, why this would happen?

This plot does not provide enough information to understand the traffic in your experiment. You will need to analyze the log data more carefully to understand the results.
A few things to consider:
-Over-the-air experiments are inherently unpredictable, especially in the presence of interference and varying channel conditions
-The RX_OFDM['timestamp'] field uses the node's MAC Time. The AP's MAC Time is a free-running microsecond counter. The STA's MAC Time a microsecond counter that runs freely but is updated every time it receives a beacon from the AP. Depending on whether the STA's oscillator is faster or slower than the AP, these timestamp updates can create gaps/overlaps in Rx-vs-time analyses. You may consider disabling this functionality with n_sta.enable_beacon_mac_time_update(false).

I am sorry that I am a python newer. How and where can I add "n_sta.enable_beacon_mac_time_update(false)" to the log_capture_two_node_two_flow.py to disable the sta's functionality?

I would suggest adding that call after n_ap.add_association().
