MMWAVE-STUDIO: How to execute lua script with cmd instead of the run key or lua shell when mmWave studio is already open?

Hi team,

Here's an issue from the customer may need your help:

Based on mmWave_studio_user_guide, C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\RunTime\mmWaveStudio.exe  /lua C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\Automation.lua this instruction enables launching mmWave studio and collecting data automatically in cmd. However, the script automatically disconnects and exits studio once the data has been captured.

So the customer has split Automation.lua into two parts, the first lua script (setup.lua) is to initialize studio and the second lua script (start.lua) is to start collecting data.(the instruction is C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\RunTime>mmWaveStudio.exe  /lua C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\setup.lua)

When the first script is executed with cmd, try executing the second script through cmd instead of using run in studio. If use the same instructions above, it will get an error stating that studio has been opened.

How to execute a second lua script with cmd instead of run with mmWave studio already open?

The following is setup.lua, and the customer notes the capture data, disconnect and close functions:

The following is start.lua, which retains the ability to acquire data only:

--Start Record ADC data
ar1.CaptureCardConfig_StartRecord(adc_data_path, 1)
RSTD.Sleep(1000)

--Trigger frame
ar1.StartFrame()
RSTD.Sleep(5000)

Could you help check this case? Thanks.
