How can I resolve TCP/IP error in rapid accelerator mode?

When I run Simulink model with TCP/IP Client Send and Received blocks in Rapid Accelerator Mode I get the following error.

Unable to build a standalone executable to simulate the model 'testSimulinkTcp' in rapid accelerator mode.

Caused by: In order to generate code from AsyncIO, the target hardware must be MATLAB Host or a compatible device. The error occurred for MATLAB System block 'testSimulinkTcp/TCP//IP Receive'

However, it works properly in both Normal and Accelerator modes.

Hi @Piotr,

It appears that the 'TCP/IP Receive' block being used is not supported for code generation on the selected hardware, which is a necessary step for the Rapid Accelerator target. More information about Rapid Accelerator mode can be found here:

To address this error, selecting the appropriate 'TCP/IP Receive' block for the specific hardware is required. For instance, on Arduino, the following 'TCP/IP Receive' block is necessary:
