- 1200 bps (SF9)
- 610 bps (SF10)
- 300 bps (SF12)
- 244 bps (SF12)

GPS receiver settings.
| Parameter | Description |
|---|---|
| Strict 3D Fix (Mountain) | Enables PDOP (≤5.0) instead of HDOP checking for APRS beacons. Requires at least 6 satellites. |
| Mode | Criterion | Description |
|---|---|---|
| Normal (OFF) | HDOP ≤ 5.0 | Horizontal accuracy only |
| Strict 3D (ON) | PDOP ≤ 5.0 | Combined 3D accuracy (horizontal + vertical) |
The yellow GPS 3D icon on the dashboard indicates this mode is enabled.
Note: If the criterion is not met, the beacon is silently skipped (SmartBeacon continues). PDOP mode ensures accurate altitudes in mountainous terrain, but may cause delays in forest/city where the sky is partially obscured.
| Parameter | Description |
|---|---|
| Sound | Enable/disable all sounds |
| Volume | Master volume (0–100%) |
Adjusting the volume plays a test beep reflecting the new level.
Enables repeater mode: the tracker retransmits all received APRS packets.
Uses more power. Only use if you are operating a digi-repeater.
| State | Description |
|---|---|
| OFF (disabled) | WiFi disabled |
| Connecting... | Connection attempt in progress |
| Connected | Connected, IP shown |
| Eco (retry) | Eco mode, periodic reconnection |
Once connected, the local IP and WiFi RSSI are displayed.
WiFi and BLE cannot operate simultaneously. Enabling one disables the other.

| State | Description |
|---|---|
| OFF | BLE disabled |
| ON (waiting) | Waiting for connection |
| Connected | Client connected |
WiFi and BLE cannot operate simultaneously. Enabling one disables the other.
Launches a WiFi access point for advanced configuration:
- Enable Web-Conf Mode
- Connect to the WiFi network
LoRa-Tracker-AP(password:1234567890) - Open
http://192.168.4.1 - Configure SmartBeacon, APRS filters, beacon comment, etc.
- Save, then Reboot on the T-Deck
Note: Alternatively, web-conf mode is accessible via the tracker's IP address if WiFi is enabled.
Restarts the T-Deck Note : To prevent accidental reboots from mishandling, I recommend removing the overly sensitive reboot button on the left side of the T-DECK Plus by opening the device (2 screws).
