µFR Nano Online Firmware flashing – upgrade & downgrade #
If you need to upgrade or downgrade your µFR Nano Online device, for the device connected to the desktop host (USB-connected) you may use the software tools provided for the µFR Online devices, or you can use the firmware update options of the device web configuration panel.
For the desktop, you should download the following firmware flashing software – ufr_online-flasher-oneclick.
This software tool implementation is further explained at https://www.d-logic.com/nfc-rfid-reader-sdk/software/ufr-online-flasher/.
However, this device is designed to be used primarily as a network device so that it can be entirely configured and both its firmware (uFR and ESP32) can be updated using its online fronted options.
To access its front-end panel, you need to connect the reader to your network. Then open its assigned IP address in your browser.
Further, follow the steps of the demonstration video.
Please remember that the default login credentials for the device online configuration panel are:
- user: ufr
- password: ufr
Both of the mentioned solution, desktop, and network, includes the Factory Reset option. However, be aware that the factory reset turns all the devices’ configuration options to their default values, but does not affect the firmware version.
If you need to upgrade or downgrade firmware, you need to perform this request separately.
Notice: The devices are always delivered with the most recent firmware version, so an upgrade is usually unnecessary if you are just starting to use this device. Also, if you want to use the desktop flashing tool, make sure you have the FTDI drivers running on your PC.
