## Blockers

*No current blockers*

### ~~BT RSSI Acquisition~~ (RESOLVED)
**Problem:** Cannot get reliable RSSI values for Bluetooth devices
- `hcitool rssi <addr>` - Only works for connected devices
- `bluetoothctl info` - No RSSI for cached devices

**Solution:** Switched to `bleak` Python BLE library which provides reliable RSSI via D-Bus/BlueZ.

---

## Notes

- BLE scanning now uses `bleak` Python library (reliable RSSI via D-Bus)
- WiFi scanning works well with `iw` command
- Live BT tracking auto-starts on page load (4-second scan interval)
- Historical data stored in SQLite database with auto-cleanup
- Movement detection uses statistical analysis (5-sample avg + 2σ threshold)
- Floor assignments persist in database across page reloads
- Popups stay open during live tracking updates
- Manual position override: drag floor-assigned device markers to set custom position
