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.

export config

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.

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).
