Thanks Takashi i already make it work, the main issue was that matlab/simulink 2012a request to add NXT support via "ECRobotInstaller – Simplified installation" in order to recognize all the files, after the instalation also need the "" command to update the system after all that is when it work

Hi Luis,

The error is the known one which is caused by changes on Simulink Data Object in 2012a
As MATLAB command window tells,
And restart MATLAB will solve it.

prety complicated design , just the simulink model give me an error on matlab/simulink2012

Block Error EnterButton Interface Error evaluating'InitFcn' callback of Enter Button Interface block (mask) 'nxtscara_controler/Enter

Model error unknown Undefined function or variable 'NXT.Signal'

that same error with all the interfaces,
plese some help
