Open-Source Variometer using ESP32S3 for XCSoar (WIP)

Warning

It has not been tested yet

Introduction

This project is an open-source variometer designed to work seamlessly with XCSoar, a popular flight planning and navigation software. Built around the ESP32S3 microcontroller, it leverages the power of Rust programming language and Espressif's standard libraries to ensure memory safety and high performance.

Key Features

• Collects sensor data and converts it to NMEA format for compatibility with XCSoar
• Transmits NMEA data over TCP (Wi-Fi) to XCSoar-compatible devices, such as Android smartphones or Kobe eReader

Getting Started

• Installation
• Usage
• License

Installation

Change the SSID and Password in src/util/tcp_client.rs to your device hotspot Wi-Fi details.

You can flash this project on your ESP32S3 easily.

• git clone https://github.com/LuMarans30/esp32vario-xcsoar.git
• cd esp32vario-xcsoar
• cargo build --release
• espflash flash target/xtensa-esp32s3-espidf/release/esp32vario-xcsoar

Usage

The ESP32S3 will automatically connect to your phone via Wi-Fi. To use the variometer as a device:

• open XCSoar
• Add a new device in the config page: OpenVario on port 8880

The variometer will start sending NMEA data to XCSoar over 8880.
