How can I deploy a standalone app for obtain data in real time from simulink

I create a simulink file for obtaining data from joystick, then I create an app in appdesigner to show data. In appdesigner I am using set_param() to set time simulation and get_param() to get data from output port in simulink when simulink is running that is the reason why I am using get_param() instead of sim function to run simulink. My app operates well . But afte I deploy a standalone desktop app for my project, when I test it comeout this error: Unsupported command in deployed mode: set_param.

I find that this function is not supported follow this link: https://www.mathworks.com/help/compiler/unsupported-functions.html

Have any another way to help me get data in real time from simulink and I can deploy a standalone app for using in another pc?

I am looking forward to hearing from you.

Thank you

Hello Khang,

As mentioned by you, a Simulink function, in your case set_param, is not supported by the MATLAB Compiler that is responsible for the deployment of a MATLAB App. You can also refer to the following MATLAB answer post for a similar observation and unavailability of a workaround in terms of utilizing the same functionality in a deployed app:

However, to perform real time functionality such as getting/setting the parameter of a block or any such real-time component, you can utilize the Simulink Real-Time components with the "Instruments Panel in App Designer" to connect the app with the components of the app and then deploy them onto a standalone app with "Application Compiler" for further use. You can refer to the below documentations to know more about the creation of such apps with the help of examples:

Hope this helps!
