STM32 NUCLEO H753ZI Mqtt Simulink block is not sending

[Khadratov]

Hello! With this Simulink model, containing a MATLAB function to convert the vector of numbers to ASCII, I was able to send a vector of numbers until a length of only [1x20], while with a length >20, the simulink model works normally with the external mode, with the MATLAB function being able to handle any length of any row vector as an input, but no messages are displayed on Node-red.
Is it possible that the problem would be with the STM32 Mqtt block? Perhaps you can help me, please, by telling me if there are some settings in CubeMX that I can modify.
I really appreciate any help you can provide.

Hello @Khadratov 

For question related to the Matlab/Simulink implementation on the STM32, I suggest you to ask on Mathworks forum.

Best Regards.
