Control inputs from SITL->Bridge are not applied in MSFS

[dmitriylavrovwork-stack]

Hello Marco,

I tried to set up a bridge between SITL instance and MSFS, and everything worked almost perfectly until the final step where control inputs should affect the aircraft in MSFS.

What works correctly. I followed the setup instructions step-by-step:

• ArduPilot SITL is running inside WSL2
• The Bridge application is installed and running in Windows 11

In the Bridge UI:

• SimConnect status is OK
• TX and RX sensor data are working
• Joystick connection is detected
• Axis mapping to MSFS controls is configured

When the aircraft moves inside MSFS, I can see position updates in Mission Planner, so the telemetry path
MSFS → Bridge → ArduPilot is working correctly.

The problem - control commands do not reach plane in MSFS:
When I move control inputs (ailerons, elevator, throttle) via ArduPilot/SITL:

• I can see servo outputs changing in the Bridge UI
• I can see RC channel values changing in Mission Planner
• The Bridge shows the axis mapped correctly to MSFS controls
• I tried both to deactivate joystick in MSFS, and just remove mapping between channels and control axises as you recommended

However, the aircraft in MSFS does not react at all: No aileron/elevator/throttle movement

So the path
ArduPilot → Bridge → MSFS seems to stop at the last step.

I attached a screenshot showing:

• Axis 1 mapped to ailerons in the Bridge
• Servo output changing
• RC channel changing in Mission Planner
• Despite this, the ailerons in MSFS do not move.

My environment

ArduPilot SITL running in WSL2
Bridge running in Windows 11
Mission Planner connected via UDP
MSFS 2024 + SDK 1.5.7

Do you have any ideas what i could do wrong? Any guidance on what to check next would be greatly appreciated.

Thank you in advance!
