Requirements

• Python 3.10+
• PX4 flight controller connected via USB

Setup

# Create virtual environment
python3 -m venv venv

# Activate it
source venv/bin/activate  # macOS/Linux
# or: venv\Scripts\activate  # Windows

# Install dependencies
pip install -r requirements.txt

Usage

# Activate virtual environment (if not already)
source venv/bin/activate

# Run the server
python main.py

Features

• Parameters: View and edit flight controller parameters
• Console: MAVLink shell access (run commands like mavlink status, listener sensor_optical_flow 1)
• Inspector: Live view of all MAVLink messages with Hz rates

Troubleshooting

"No serial port found": Make sure your flight controller is connected via USB and powered on.

Console not responding: Switch to another tab and back, or refresh the page. Only one feature can use the serial port at a time.

Parameters not loading completely: Stay on the Parameters tab while loading. The Inspector runs in the background and can interfere.
