How the scanner works
- Uses your phone's Bluetooth to scan for your dog's BLE beacon — no internet or cell signal needed.
- Tap "Start BLE Scan" to list nearby devices. Each shows its name and signal strength (RSSI) only.
- Pick your dog's beacon to track it. We never show MAC addresses or private identifiers — just the name and signal.
- The radar screen shows signal strength, a closer/farther indicator, and vibrates as the signal grows stronger.
- Scans refresh continuously every 1–2 seconds. Walk around and watch the signal climb as you near your dog.
Quick tips
- Turn on your dog's beacon before you start scanning.
- Stronger signal (closer to 0 dBm) means your dog is nearer.
- If the signal drops, change direction and scan again.
- Works in woods, trails, and campus — anywhere Bluetooth reaches.
Note: Live BLE scanning works best in Chrome on Android or desktop. Some browsers don't support Web Bluetooth scanning.
