Loko GPS Tracker Configuration Tool

How to Use the Loko Configuration Tool

The Loko Online Configuration Tool lets you configure Loko Air and Ground units directly from your browser using the Web Serial API — no software installation required. You need Google Chrome (desktop) and a USB cable to connect your device.

Step-by-step connection

1. Open this page in Google Chrome on a desktop computer (Windows, macOS, or Linux).
2. Power on your Loko Air or Ground unit.
3. Connect the device to your computer with a USB-C cable.
4. Select the correct tab (Air Unit or Ground Unit) in the tool above.
5. Click Connect, then choose the correct serial port from the browser prompt.
6. The tool reads the current device settings automatically.
7. Edit any parameters and click Apply to save them to the device.

Configurable parameters — Air Unit

The Air Unit is the GPS tracker attached to the asset you want to track. The following parameters can be configured:

• Device ID 1 & ID 2 — Unique identifiers that pair the Air Unit with a Ground Station. IDs must match between paired devices.
• Radio frequency (Hz) — LoRa transmission frequency. Must match the Ground Station. Default bands: 868 MHz (EU), 915 MHz (US), 923 MHz (AS).
• GPS update interval (seconds) — How often the Air Unit transmits its GPS position. Shorter intervals increase battery drain. Range: 1–3600 seconds.
• Trace record period — How frequently GPS points are saved to the on-device data logger (up to 6,500 points).
• Firmware version — Displays the current firmware on the device. Update from the Firmware page when a new version is available.

Configurable parameters — Ground Unit

The Ground Unit receives GPS data from one or more Air Units and forwards it to the Loko mobile app via Bluetooth. Parameters include:

• Device ID 1 & ID 2 — Must match the paired Air Unit(s). A single Ground Station supports up to 30 Air Units simultaneously.
• Radio frequency — Must match all Air Units it should receive from.
• Firmware version — Keep the Ground Unit updated for best range and reliability.

Battery life and update interval

The GPS update interval has the single largest impact on battery life. The tool displays an estimated battery life based on the interval you set. At a 60-second interval, expect roughly 30 days of runtime — up to 1 year at longer intervals. At a 600-second interval, runtime extends to several months. At intervals above 3,600 seconds, battery life reaches 12 months or more on a full charge.

Troubleshooting

• No serial port listed — Make sure the device is powered on and the USB cable supports data (not charging only). Try a different cable or port.
• Connection fails immediately — Another app may be using the serial port. Close it and try again.
• Tool shows blank values — Click Read again after connecting. If it persists, power-cycle the device and reconnect.
• Browser not supported — Web Serial API requires Chrome or Edge (desktop). Use the desktop configuration app as an alternative on unsupported browsers.
