GPS and Buzzer not working for Embedded Coder for Simulink


As PX4 is not really designed for the vehicle I’m about to control and regulate, I decided to build my own flight controller by using the
Embedded Coder Support Package for PX4 Autopilots, designed by MathWorks.

I’m flashing my Pixhawk 4 with it, and so far everything’s fine: sensor data are readable, pwm output are operating as expectation. There is, sadly, one thing that don’t work as is should: The GPS and Buzzer is not working. Funnily, the LED works! Is anybody experiencing a similiar problem? I used the uORB write block in this case, just like the example given my MathWorks.

Thanks in advance!
