So far, we’ve covered how to set up Tags and Anchors.
Now, we’ll explain the final step: configuring and integrating the Listener.
What is the Listener’s Role?
The Listener is a core device that collects tag data and integrates it with your system.
If this process is not configured properly, real-time location tracking will not work, so accurate setup is essential.
✅ Listener Functions
- Tag → Listener → Transfers data to the server (software)
- Real-time tag positioning visualization on maps (floor plans)
- Monitoring and visualizing tag movements within indoor spaces
Connecting the Listener & PAN ID Configuration
✅ How to Connect the Listener
- Connect the Listener to the USB port on your PC using a USB cable.
2. Launch the GrowSpace UWB configuration software.
3. Select the COM port connected to the Listener (e.g., Silicon Labs CP210x USB to UART Bridge (COM3)) and click the [Connect] button.
4. Once connected, set the PAN ID.
What is a PAN ID?
The PAN ID defines the UWB network group, and the Anchors, Tags, and Listeners must share the same PAN ID for proper data transmission.
What if PAN IDs are different?
- Listener won’t collect tag data.
- Real-time location data won’t appear.
- Ensure all devices have the same PAN ID (e.g.,
0x0000).
Low Pass Filter Configuration
The Low Pass Filter helps reduce noise in location data, providing a more stable signal.
✅ How to Configure
- Enter your desired value in the Low Pass Filter field.
- Click [Save] to apply the changes.
- Verify that settings have been correctly applied.
What is an appropriate Low Pass Filter value?
- Lower values (e.g.,
0.1): Fast response but increased noise. - Higher values (e.g.,
0.9): Reduced noise but delayed location updates. - Recommended range:
0.5 ~ 0.8
Setting values too high or too low affects signal quality. Testing is advised to find the optimal value.
Integrating Listener with Maps (Floor Plans)
Once the Listener is set up, you can view tag data on maps (floor plans) in real-time. However, setting up maps isn’t mandatory.
When is map integration necessary?
| Setup Method | Necessity |
|---|---|
| Coordinate data only | When only X, Y, Z coordinates are required (no map needed) |
| Map (floor plan) upload | To visually track tags in indoor environments (map required) |
| Large spaces (factories, logistics centers, hospitals, etc.) | Map setup required for easy asset and route monitoring |
You can either monitor coordinates numerically or set up a map as needed.
For detailed instructions, see the Tag Map Setup Guide.
Advantages of setting up a map:
- Real-time tracking of tags on facility maps
- Analysis of personnel movement paths and space optimization
- Identification and improvement of inefficient movement paths
We’ve now covered the setup process for Tags, Anchors, and Listeners step by step.
Once you finish the map integration step, you can fully utilize the GrowSpace UWB system.
