AirSim with ROS WSL2 Connection Error

[blakermchale]

I've been trying to connect my WSL2 ROS instance to AirSim on Windows. The settings.json I am using is front_stereo_and_center_mono.json from airsim_tutorial_pkgs. When I run the command roslaunch airsim_ros_pkgs airsim_node.launch output:=screen host:=$WSL_HOST_IP it gets connected, but starts outputting this error:

Exception raised by the API:
rpclib: function 'simGetGroundTruthEnvironment' (called with 1 arg(s)) threw an exception. The exception contained this information: Vehicle Sim-API for 'SimpleFlight' is not available. This could either because this is not a simulation or this vehicle does not exist.

Currently, I am using Ubuntu 20.04 in WSL2 and have confirmed that the ros packages work on another linux computer running only Ubuntu 20.04.

Has anyone ran into this issue and resolved it?

I have same issue - with ROS melodic in WSL Ubuntu 18.04 in Windows 10 - Unreal 4.25

In WSL, I set
ROS_IP = '172.27.154.160'
ROS_MASTER_URI = 'http://172.27.154.160:11311'

in Windows 10: IP: 172.27.144.1

Airsim is git-cloned from the update version.

roslauch is similar to Blake McHale (@blakermchale) : roslaunch airsim_ros_pkgs airsim_node.launch output:=screen host:=172.27.144.1
And I got the same output. Waiting for solution.

Is there any progress on this? I have the same issue.

I found this has something to do with the vehicle name in AirSim settings.json.
If you change the name like this:
...
"Vehicles": {
"ComputerVision": {
...

the error goes away.

xistix Can you send me your settings.json? I tried to change it like you describe but it doesn't work as expected.

xistix Thanks! I was able to get it working by changing the name to "SimpleFlight". You also have to make sure that there is a settings.json in your WSL Documents/AirSim directory
