Firmware for M5Stack Unit C6L

D.A.R.S.
Drone Awareness
Relay System

See every drone around you — even the ones your phone misses.

D.A.R.S. turns your M5Stack Unit C6L into a passive drone detection relay. It silently monitors WiFi and Bluetooth for Remote ID beacons broadcast by drones, then re-transmits them via BLE so your companion app receives a clean, unified feed — regardless of how each drone is broadcasting.

What it does

Everything in one device

A single M5Stack Unit C6L running D.A.R.S. replaces a stack of separate monitoring tools.

📶
Passive WiFi Scanning
Monitors the 2.4 GHz band in receive-only promiscuous mode. Captures Remote ID beacons from drone beacon frames, action frames, and probe responses.
🔵
BLE Relay
Receives standard OpenDroneID BLE advertisements and re-broadcasts them via BLE — providing a clean, unified feed to your companion app.
📡
LoRa Mesh Networking
Optional LORA mode pairs with your phone via BLE GATT and acts as a long-range LoRa mesh radio. Compatible with MeshCore companion app (limited support).
🌍
Global Coverage
Detects drones transmitting Remote ID on 2.4 GHz via WiFi and Bluetooth. Operates under EU, US, JP, and World regulatory domains.
🔔
Drone Alerts
Built-in buzzer plays a detection alert when a new unique drone is detected. OLED display shows live drone count. Alerts are configurable and stored across reboots.
⚡
Easy Flashing
