PX4 issue with SIMULINK

I've a problem that when i deploy simulink model my drone spin on itself. ( no PID only THRUST ).
i can't find the problem
any suggestions?

How to build this code?

Hi
I make it, but there are some errors, do I need mavlink lib?
Thanks

Change UDP communications address to localhost from '192.168.46.2'.

Hello,
I have a Simulink model of a quadcopter which has the required infrastructure to send data to and receive from PX4 sitl. I connect the s-function block, the model compiles successfully; however, UDP communication is not established.

I changed the following line in PX4Main.c from:

_server.sin_addr.S_un.S_addr = inet_addr("192.168.46.2");
to
_server.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");

I create the mex file using 'BuildPX4Interface.m'.

I am not using a Ubuntu machine to run the px4 software by the way. It simply runs as a separate window after I type 'make px4_sitl none'. The only message after I am getting 'Simulator connected on TCP port 4560.' is

ERROR [simulator] poll timeout 0, 111

Thanks in advance.

Simulink QuadRotor Model along with MAVLink Interface

@MichaelSkadan Is it possible to add the QuadRotor, IMU and GPS Simulink Blocks to this repository as well in order to get started as described in "User Guide.docx" ? It would be great to have some baseline model which works with the PX4-Simulink_MAVLink Interface, before I start making complicated vehicle models.
