When creating or running a model using the MATLAB And SImulink Robotics toolbox, I get the following error:
Error evaluating 'InitFcn' callback of block_diagram 'untitled'. Callback string is 'RPInit'
Caused by:
  • Changing property 'UnconnectedLineMsg' is not allowed

To fix the error, go to the Simulink model settings and set the UnconnectedLineMsg connectivity diagnostic to 'none'. See how to do it in the picture below:

clc; clear all
model = 'bright2';
close_system('model',0)
open_system(model)
setpref('MathWorks_Embedded_IDE_Link_PIL_Preferences','COMPort','COM4');
setpref('MathWorks_Embedded_IDE_Link_PIL_Preferences','BaudRate', 115200);
setpref('MathWorks_Embedded_IDE_Link_PIL_Preferences', 'enableserial', true);
set_param(model, 'CreateSILPILBlock', 'PIL');
close_system('untitled',0)
rtwbuild([model '/Brighttest'])
Error using pilcontriller (line 10)
Changing property 'CreateSILPILBlock' is not allowed
I found an error and would like to ask how to fix it.
