Extra command line "-f json:"

I’m attempting to conduct simulations using a Matlab physics model. Initially, everything was working fine. However, at some point, the command “-f json:” started generating an error stating “Failed to connect to SITL instance.” I observed that this error occurs when the introduced command isn’t recognized. It’s worth noting that this procedure was functioning correctly for me two months ago.

What about reading the documentation JSON interface — Dev documentation
-f works with sim_vehicle.py
–mode works with vehicle binary… guess what MP is using… .:slight_smile:
