mavproxy config sitl

Hallo

Iam use a pi connected to Ardupilot-Device
and sitl running on a VM.

Ardupilot-Device — pi:192.168.1.112:mavproxy — vm:192.168.1.103:mavproxy:sitl

pi:mavproxy
/usr/bin/python3 /usr/local/bin/mavproxy.py --master=/dev/ttyACM1 --baudrate 115200 --out 192.168.1.103:14550

vm:sitl:
./Tools/autotest/sim_vehicle.sh -L MY -v APMrover2 --map --console
/usr/bin/python /usr/local/bin/mavproxy.py --master 0.0.0.0:14550 --sitl 127.0.0.1:5501 --out 127.0.0.1:14550 --out 127.0.0.1:14551 --cmd= --map --console

pi:mavproxy can read param and write param
vm:sitl can read param, but not write

What can i do?

I’m a bit confused on what you’re trying to achieve here. You appear to have a flight controller connected to the Pi, which you are forwarding to the VM.

You also have a SITL instance running on the VM?

So you have 2x instances of MAVProxy running on the VM, one for the Pi and one for SITL?
