Bluefly

Bluefly is the essential companion app for Bluefly Vario.

Key Features:
Advanced Kalman Filtering: Experience ultra-smooth and near-instant vertical speed (vario) response. Bluefly processes raw pressure data using a sophisticated Kalman filter to eliminate sensor jitter while maintaining maximum responsiveness.

Local TCP Bridge: Turn your device into a flight data hub. Create a local TCP server (localhost) to pipe your vario data directly into other flight applications like XCSoar, or LK8000 running on the same device.

IGC File Management: Download your flight logs from the Bluefly.

Complete Hardware Configuration: Access every internal setting of your Bluefly Vario. Adjust audio thresholds, lift/sink tones, output modes, and power settings through a clean, grouped interface.

Raw Data Terminal: Monitor the live serial stream from your device. Includes a "freeze" feature for inspection and long-press copying for easy debugging or log sharing.

Modern & Persistent: Optimized for Android 10 through Android 16. The app features a persistent background service (tied to the TCP server) and high-priority threading to ensure your data stream never drops, even with the screen off.

Pilot-Focused UI: A high-contrast, clean interface designed for visibility. Toggle between Metric (m, m/s) and Imperial (ft, ft/min) units with a simple tap on the display.

Permissions & Privacy:
Bluefly is a pure utility app. It does not collect personal data, use analytics, or require an internet connection. It requires Bluetooth and Location permissions solely to communicate with your Vario hardware and Storage permissions to save your flight logs to your chosen directory.
