About this app

D-Tracer — FPV Telemetry & Flight Planning

D-Tracer is an Android application designed for FPV pilots using ELRS protocol and EdgeTX transmitters. The app connects to the transmitter via USB OTG cable and, after minimal configuration in EdgeTX, begins streaming telemetry data directly to your smartphone.

Key Features
USB OTG telemetry: Receive flight data directly from your transmitter with minimal EdgeTX setup.

ELRS protocol support: Optimized for FPV systems running EdgeTX or OpenTX.

Real-time flight monitoring: Display the drone’s current position on the map, visualize its trajectory, and track essential telemetry.

Telemetry data: GPS coordinates, speed, altitude, battery voltage, current consumption, and RSSI link quality.

Flight planning: Create and evaluate routes before flying, including total distance and segment lengths.

Single waypoint marking: Place one marker on the map. The app draws a dashed line between the drone and this anchor, showing direction and distance to the selected object.

Offline maps: Cache maps in advance for use without internet connection.

Usage
To function properly, the application requires either an active internet connection or pre-cached maps. Connect your transmitter to the smartphone via USB OTG cable, configure EdgeTX to output telemetry via USB, and DTracer will start receiving and displaying flight data.

Benefits
Enhanced situational awareness during FPV flights.

Easy route planning and evaluation before takeoff.

Real-time monitoring of drone performance and link quality.

Convenient map interface with telemetry overlay.

DTracer is built for FPV enthusiasts who want reliable telemetry, navigation, and planning tools in one app. Whether you are tracking your drone’s live position or preparing a route, DTracer provides the essential features to make your flights safer and more efficient.
