Control Parrot minidrone with joystick controller

Hi, I changed the VSS_COMMAND to the 1. Then I deployed the flight controller to the hardware. But, I cannot control with the joystick controller. I tried on the simulation, the joystick controller was working well.

Also, I tried with signal builder as well. I modified the signal builder in the reference value server, then I deployed the flight controller to the hardware. But it did not work as well.

Does anyone know what is the problem?? ( I followed the Webinar - https://www.mathworks.com/videos/programming-drones-with-simulink-1513024653640.html)
