UAV Toolbox Support Package for PX4 Autopilots Error

Whenever i try an Example simulation on my Pixhawk 1 i get this error. Any fixes?

Error occurred while executing External Mode MEX-file 'ext_comm':

Unexpected response from target. Expected EXT_CONNECT_RESPONSE.

Component:Simulink | Category:Block diagram error

Unable to connect to the 'PX4 Pixhawk 1' target for 'px4demo_Read_Parameter'

Hello,

Can you confirm that you have run the PX4 Hardware setup screens and inserted an SD card to Pixhawk 1 with custom startup script as described here?

Also, please check that the Enable MAVLink checkbox in the Configuration parameters are not selected.
