IWR1642BOOST: Radar Studio Automation using Matlab

BL

Part Number: IWR1642BOOST

I want to automate the Radar Studio using Matlab. I have found the same topic in this thread, however I could not get the sample code from TI to work.
https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/t/671275?AWR1243BOOST-Radar-Studio-Automation


I have copied and replaced the "Radar Studio.exe.config" to "ti\mmwave_dfp_01_00_00_01\rf_eval\radarstudio\RunTime" directory. I have two issues with the example code:
- When opening LUA Shell in the Radar Studio and run "RSTD.NetStart()", the returned value is 0 (in the Matlab-Script says that the returned value should be 30000 when no error).
- When running "RSTD_Interface_Example.m" in Matlab, i got an error:" 'RtttNetClientAPI.dll' could not be found in the .NET Global Assembly Cache (GAC). "

How can I fix this issue ?

Thanks very much

Bien

    Bien,

    We are looking into this question and will get back to you. This type of question does require a bit of digging.

    Hi Bien,

    When running RSTD.NetStart() in the LUA Shell, the 0 return value is correct - this is what we expect. You should also see the following message in RadarStudio's Output window: "RstdNet: Port 2777: Listening.."

    The 30000 return value is what you would expect when calling the Init_RSTD_Connection() command in the RSTD_Interface_Example.m script.

    Could you please confirm that the DLL file in line 4 of RSTD_Interface_Example.m actually exists at that location in your installation? If not, could you update the path in line 4 to point to the correct location?

    Also, could you please confirm the exact version of RadarStudio that you are using? Is it from the mmwave_dfp_01_00_00_01 package, or do you have a different version?

    Best Regards,
    Anand

    Hi Anand

    Sorry for the late reply.
    I have all of the 4 dll-files (RstdNet.dll, RtttNet.dll, RtttNetClientAPI.dll, RtttNetClientController.dll) in the same directory of RSTD_Interface_Example. (Do I also have to copy these .dll files to the directory of RadarStudio ?)

    I'm using the "mmwave_dfp_01_00_00_01" package.

    Thanks
    Bien

    Hi Bien,

    The path to the dlls is hardcoded in line 4 of RSTD_Interface_Example.m - could you make sure this is pointing to the correct location?

    You do not need to copy the .dll files to the same location as the script - it may be better in fact to run the script from a different location instead.

    Best Regards,

    Hi Anand

    The dll path in RSTD_Interface_Example.m was adjusted to the current direction. The hard-coded path is commented out and replaced by the new path as showed belowed (dll files are already placed in Matlab directory).

       % RSTD_DLL_Path = 'C:\ti\mmwave_dfp_01_00_00_01\rf_eval\radarstudio\Clients\RtttNetClientController\RtttNetClientAPI.dll';

       RSTD_DLL_Path = 'RtttNetClientAPI.dll';

    There is another thing which I'm not sure if it cause the problem that is:

      -  I was using a Matlab-Server ,which is not the one installed on my computer, to run the  "RSTD_Interface_Example.m", but I don't think it makes the software not able to find the .dll

    Thanks Bien

    Hi Bien,

    To keep it simple, would you be able to run with Matlab running locally on the same computer as RadarStudio?

    Hi Anand

    Yes, I also planed to run it with a local Matlab to test it. I'll check it.

    Thanks

    Hi

    I checked it again, and i seems like the problem is the directory path. When I use the absolute path instead of relativ, it works. Namely:
    RSTD_DLL_Path = 'D:\My_Project\RtttNetClientAPI.dll'; --->> working
    RSTD_DLL_Path = 'RtttNetClientAPI.dll'; --->> not working

    Thanks
