Can't receive packages for Json Interface

[Kinggrass]

Hi @chrisdalke,

awesome project you setup here.

I also want to experiment a litte bit but are hanging some time at the point where I don't get it to work to receive these packages.

I also changed like you sugesseted in the README to change the target json interface to the IP-Address of the host but doesn't change anything for me.

What I want to ask is if ou have any advice how I could check anything to narrow it down?

Best regards,

Edit:
The GQ can connect to it but then ArduPilot is waiting on JSON sensor messages and is resending servos continously.

Hi @Kinggrass ,

I think I may have some solutions as I came across the exact same issue.

I'm not running the ArduPilot SITL in a Docker container like in the project, I'm running it in WSL2.

sim_vehicle.py -v ArduCopter --map --console --model JSON:192.168.128.1

First set the JSON IP to your local windows default gateway, which I think you already have.

Second, ensure that Unity editor is not blocked in any capacity in the Windows Firewall settings.

Go to "Windows Defender Firewall with Advanced Security" > "Inbound Rules" , and remove the rule that blocks the Unity Editor.

Third, add port 9002 to the inbound rules.

This allowed me to receive incoming messages on port 9002 from the SITL and send back static JSON packets. https://github.com/bwally0/ardupilot-unity3d/blob/main/ArduCopterSim/Assets/Scripts/CopterJsonInterface.cs
