The main screen is displayed at startup and shows all real-time information.
| Element | Description |
|---|---|
| Callsign | Your APRS callsign |
| APRS Symbol | Icon representing your station |
| Date/Time | Format DD/MM HH:MM (GPS time) |
| GPS 3D | Golden icon when strict 3D fix mode is enabled in settings (beacons then require PDOP ≤5.0 instead of HDOP) |
| WiFi | Green icon when connected |
| Bluetooth | Green icon when a BLE client is connected |
| Battery | Percentage + color (green >50%, orange 20–50%, red <20%) |

Satellites — Number of satellites + HDOP quality indicator:
-
+HDOP ≤ 2.0 (excellent) -
-HDOP 2–5 (good) -
XHDOP > 5 (poor)

Locator — 8-character Maidenhead grid square (e.g.
JN03AA12) - Position — Latitude / Longitude in decimal degrees
- Altitude — in meters
- Speed — in km/h
-
Frequency — In MHz (e.g.
433.775) - Speed — In bps
The 4 most recently received stations with their RSSI (dBm) and SNR (dB).
| Button | Color | Action |
|---|---|---|
| BCN | Red | Send an APRS beacon immediately (if GPS quality sufficient: ≥6 satellites and HDOP ≤5.0) |
| MSG | Blue | Open messaging |
| MAP | Green | Open the map |
| SET | Purple | Open settings |
The tracker sends beacons automatically using SmartBeacon logic:
- More frequent when moving fast
- Less frequent when stationary
- GPS requirements: at least 6 satellites and HDOP ≤5.0 (or PDOP ≤5.0 in strict 3D mode)
The BCN button allows sending a manual beacon at any time, under the same GPS quality conditions.
