I am facing problems connecting multiple sensors to my EV3 brick. They do show up in the port view and read correct values. However when I run code like:

 color_sensor = colorSensor(robot,2);
 touch_sensor = touchSensor(robot,1);

I get errors on the second line. The same thing happens when I swap the line (meaning it's not related to a certain sensor) and I've also tried using other ports.

I am using Matlab R2015a and the error is as follows:

>> bci_ev3
Error using error
