Field-ready Search and Rescue coordination over MeshCore + BLE
MeshCore SAR helps teams coordinate in low-connectivity or no-connectivity environments with messaging, voice, images, maps, and live location context in one app. It uses the MeshCore protocol over LoRa for long-range, infrastructure-free communication. iOS TestFlight: https://testflight.apple.com/join/nCZYMPPz
- Rapid mesh chat for both 1:1 and group coordination
- On-demand voice (Codec2) and image (AVIF) transfer tuned for low-bandwidth links
- Offline-first mapping with tactical overlays and SAR incident markers
- Live team location, movement trails, and shareable tactical drawings
| Area | What you get |
|---|---|
| Messaging | Direct and group chat over mesh, with contact/room awareness from live telemetry |
| Voice | Push-to-talk voice clips (Codec2), fetched on demand when play is pressed, auto-play on completion |
| Images | Camera/gallery image sending (AVIF), auto-compression, tap-to-load receiving, full-screen viewer |
| Maps | Street/topo/satellite/terrain layers, offline tile downloads, optional MBTiles import |
| SAR Operations | Team markers with freshness indicators, SAR markers for incidents and staging points |
| Tracking | Continuous GPS updates, personal trails, distance/duration trail stats |
| Trail Interop | GPX export/import for trail sharing and reuse |
| Tactical Drawing | Line/rectangle drawing, distance measurement, drawing sharing to channel/room |
