BOOSTXL-AOA: Fail to run IQ data collection on 2 passive node with AoA

Part Number: BOOSTXL-AOA

Greetings,

As I go through the tutorial and successfully run both the GUI demo (rtls_ui) and python scripts( rtls_aoa_iq_with_rtls_util_export_into_csv.py ), with the setup 1 master node, 1 slave node and 1 passive node + AoA board. 

Now I get the 2nd passive node + AoA board, and I plan to collect IQ data on two passive nodes at the same time. To this end:

  1. Make a copy of rtls_aoa_iq_with_rtls_util_export_into_csv.py, rename as rtls_aoa_iq_with_rtls_util_export_into_csv2.py, and change the passive node port name
  2. In terminal run 

             ```

                       python -u *csv..py &

                        python -u *csv_passive2.py

                ```

 

I notice only one passive node successfully record the IQ data, while another node FAIL, the log information is

```

```




Is it possible to do so?
