Hi guys,
Im running 2018b version, with Ubuntu 18.04. I already installed the support package and fixed the toolchain for the firmware.
I just bought my first pixhawk 4 (by radiolink), and im trying to simply read the accelometer sensor with a simple model in the simulink:

when I try to build the model and start read the values, I get the following message:

I opened the Model Configuration Parameters, and tried to figure out what ports should I set.
I opened a new terminal window and type lsusb, and I found out the it is "ttyACM0", so I set this port in both "Building Options" and "External Mode", but It still dosent work and I get the same error.
Here is how I tried to set the ports on the Model Configuration Parameters:

Iftach.

How have you connected the Pixhawk to the PC. Direct USB cable connection or via telemetry. This port mapping might help.
