Run Simulation from Raspberry Pi

A step-by-step guide to running the simulation from a Raspberry Pi and connecting it to your computer.

Install Sim & WSL Ubuntu 24.04

Download Raspberry Pi Imager:
https://www.raspberrypi.com/software/

Set the following:

• Device: Raspberry Pi Zero 2 W
• OS: Other General Purpose → Ubuntu → 24.04
• Storage: Select your SD card (Generic Storage Device)
• Next
• Edit Settings
• UNDER GENERAL
• Enable Set hostname = sim
• Enable Set username and password
• Username = sim
• Password = sim
• Enable Configure wireless LAN
• SSID = MST-GUEST
• Password = Miner2020
• Enable Hidden SSID
• Wireless LAN country = US
• Enable Set locale settings
• Time zone = America/Chicago
• UNDER SERVICES
• Enable Enable SSH
• Select Use password authentication
• Save

Flash the image to the SD card.

Set Up the Raspberry Pi and Connect via SSH

Insert the SD card into the Pi and plug in:

• Power (micro USB power port)
• Keyboard (micro USB data port)
• Display (micro HDMI)

Once the Pi finishes booting, run:

ip a

Look for your IP under wlan0, for example:

inet 192.168.1.15/24

On your computer, open PowerShell and connect:

ssh sim@192.168.1.15

When prompted:

• Accept fingerprint → type yes
• Password → sim

Set Up the Repository and Environment

Clone the test repository onto the Pi:

git clone https://github.com/PG13park/simpitest.git
cd simpitest

Install uv:

curl -LsSf https://astral.sh | sh

Set up the environment:

uv sync

---

Allow MAVLink Through Firewall (Windows)

On your computer, open PowerShell as Administrator and run:

New-NetFirewallRule -DisplayName "Allow MAVLink 5762 TCP" -Direction Inbound -Protocol TCP -LocalPort 5762 -Action Allow

New-NetFirewallRule -DisplayName "Allow MAVLink 5762 UDP" -Direction Inbound -Protocol UDP -LocalPort 5762 -Action Allow

---

Start the Simulation

Open your simulation in Unreal Engine.

Then open a new terminal and start WSL:

wsl -d Ubuntu

Navigate to your project:

cd /mnt/c/.../.../SUAS-2025

Start the Unreal editor player and run:

./run_container.sh

---

Connect from the Raspberry Pi

From the Pi (SSH session), run:

uv run AirSimControllableFlight.py

---

Fix Connection Issues

If you are not SSH’d in or the connection fails, manually set the IP.

Edit the file:

sudo nano AirSimControllableFlight.py

Replace the connection address with your computer’s IP (find it using ipconfig on Windows).

Save and exit:

• Ctrl + O
• Enter
• Ctrl + X

Done

You should now have the simulation running and connected to your Raspberry Pi.
