Drone Awareness
Relay System

Better airspace awareness for safer drone operations.

D.A.R.S. gives drone operators a complete picture of who else is flying nearby. It turns your M5Stack Unit C6L into a passive Remote ID receiver and relay — silently monitoring WiFi and Bluetooth for Remote ID signals from surrounding drones and delivering a unified feed to your companion app.

Know what's sharing your airspace before problems arise. Whether you're flying professionally, at a club field, or in complex environments, D.A.R.S. helps you operate with confidence.

What you're buying: the firmware that makes this work. A 3D-printable case model and LoRa mesh (MeshCore) mode are included free as a bonus. The D.A.R.S. Android app is a free download for everyone (with an optional in-app PRO upgrade).

D.A.R.S. is independent third-party firmware and is not affiliated with, endorsed by, or produced by M5Stack Technology Co., Ltd. "M5Stack" and "Unit C6L" are trademarks of M5Stack Technology Co., Ltd. D.A.R.S. is likewise not affiliated with or endorsed by the MeshCore project; "MeshCore" is the property of its respective owner, and LORA-mode compatibility is provided on a best-efforts basis.

What it does

Complete airspace awareness in one device

Know which drones are sharing your airspace. D.A.R.S. consolidates all nearby Remote ID signals into a single live feed on your phone.

📶

WiFi & Bluetooth Scanning

Passively monitors the 2.4 GHz band for Remote ID signals from nearby drones — both WiFi beacon frames and BLE advertisements, all captured simultaneously.

🔵

Unified Feed to Your Phone

Re-broadcasts all detected Remote ID signals to your companion app via BLE, giving you a single, consolidated view of every drone in the area regardless of how it's transmitting.

Free Bonus

📡

LoRa Mesh (MeshCore)

Optional LORA mode turns the device into a BLE-connected LoRa mesh radio compatible with the MeshCore app. Note: LORA mode is a companion radio — Remote ID detection is inactive while in this mode. Provided as a free bonus.

🌍

Works Everywhere

Detects drones transmitting Remote ID on 2.4 GHz WiFi and Bluetooth. Covers EU, US, JP, and World regulatory domains — take it wherever you fly.

🔔

Instant Drone Alerts

Get alerted the moment a new drone enters the area — visual count on the OLED display and a configurable audible alert. Never be caught unaware.

⚡

Easy Flashing

No drivers, no IDE. Open the web installer in Chrome, plug in your device, enter your license key — firmware is flashed in under 60 seconds.

Operating Modes

Three modes, switchable on the device

Switch modes from the on-device button menu — or remotely from the companion app for DARS and USB. Changing the mode reboots the device.

DARS Mode default

The everyday mode. Passively scans WiFi & Bluetooth for drone Remote ID and delivers every detection to the D.A.R.S. Android app over an encrypted Bluetooth LE link. It does not rebroadcast Remote ID over the air.

USB Mode wired

The same Remote ID scanning as DARS, but detections stream to the Android app over a wired USB-C (OTG) cable instead of Bluetooth — ideal when Bluetooth is unavailable or for maximum reliability.

LORA Mode free bonus · MeshCore

Turns the device into a BLE-connected LoRa mesh radio for the MeshCore app. Remote ID detection is inactive in this mode — use DARS or USB mode for drone awareness.
