Attempting connection with Arduino and Matlab

Hi! I am using simulink and connection an arduino uno board to my mac via USB. My problem is, whenever I run my code, the command window says, " attempting connection . . . . . " This takes a long time, about 10 seconds. Any way to make it faster?

Hello Bryan,

The origin of this issue could be that the MATLAB serial command is taking longer to respond. Try opening the arduino.m file and replacing the lines 89 to 92:

                for i=1:7,
                    fprintf(1,'.');
                    pause(1);
                end

with these ones:

                for i=1:15,
                    fprintf(1,'.');
                    pause(1);
                end

to see if that solves the issue.
