The extracted project root folder contains subfolders with uFR Online Configurator software executive files for supported operating systems.
Go to the folder named after your PC/laptop operating system and run the executable file of the uFR Online Configurator software tool.

3. uFR Online Configuration – Connect the reader

Connect µFR Nano Online NFC reader to your PC/Laptop via USB cable and click the Connect uFR Online button.
This will establish communication with the connected device and display the device configuration settings.

4. uFR Online Configurator – Switch modes

As via the device’s frontend configuration panel, this software also allows you to quickly change your µFR Nano Online device modes by clicking the desired mode button at the top of the screen.

4.1  – uFR Online Configurator – Slave Mode

4.2  – uFR Online Configurator – Master Mode

4.3  – uFR Online Configurator – BLE Mode

4.4  – uFR Online Configurator – BLE HID Mode

4.5  – uFR Online Configurator – BT Mode

4. uFR Online Configurator – View/Edit device configuration

Click the Edit Device Configuration button to view and edit all the device configuration settings.


Click the Edit Device Configuration button and find the desired feature (in our case it is BT mode).

The option Value is an actual desired value for the features (Keys) that require a specific parameter/value entry.  
The rest of the options refer to the status of those specific functions (Keys) and the value can be:

1 – for the status Enabled
0 – for the status Disabled.

To modify the device current settings manually, follow the steps:

  • Click the Edit Device Configuration button 
  • Find the desired feature (in our case it is BT mode).
  • Edit the feature Value (we will replace the Value 1 with 0 to disable the BLE mode) 
  • Click the Save Configuration To Device button to apply the changes.

5. uFR Online Configurator – Export/Import device configuration

Export and Import device configuration function provides the ability to save one or more versions of device settings. The software stores the configuration in a JSON file that can be easily imported back. In this way, multiple versions of the configuration can be backed up and applied to the device very quickly without the need to edit each feature individually.

5.1  – uFR Online Configurator – Export device configuration

Click the Export Device Configuration button to export the current device configuration file.

Select the location on your computer where you want to save the exported file.
You can optionally enter the appropriate file name or just confirm the default file name that matches the serial number of the device.

Click the Save button to save this configuration.

5.2  – uFR Online Configurator – Import device configuration

Click the Import Device Configuration button to import the previously saved configuration file.

Select the desired JSON file and confirm the import to apply the previously saved device configuration settings. 

6. uFR Online Configurator – Reset configuration to the factory default

This function resets the device configuration to the factory default settings. 
Click the Reset Configuration To Factory Defaults button to reset the device configuration.

NOTE: The factory reset will reset the device network connection so the online configuration panel will no longer be available on the previously assigned device IP. However, the reset does not apply to the ESP32 and Nano reader firmware (both embedded into the µFR Nano Online device).
