A corrupted µFR Nano Online firmware recovery – desktop app

A corrupted µFR Nano Online firmware recovery – desktop app If you are experiencing a problem with a corrupted firmware of your µFR Nano Online device, and it cannot be connected to your network, or for some other reason you cannot access its web backend configuration in your browser, you need to recover the device using the desktop tools. Windows desktop tools – µFR Nano Online firmware recovery Plug the device into your Windows machine USB port and make sure your FTDI drivers are running properly. As you are probably already aware, the µFR Nano Online device consists of the two joined hardware, uFR Nano and ESP32, both having individual firmware. Therefore, one firmware flashing tool may not recover the entire device. It is most likely that the device’s ESP32 firmware failed. The console flasher can flash the uFR Nano reader of the device, but you first need to fix the ESP32 with the following  ufr_online-flasher-oneclick  tool (explained at https://www.d-logic.com/nfc-rfid-reader-sdk/software/ufr-online-flasher/). In case you have trouble detecting the device on the Windows machine, make sure you meet the following conditions: – FTDI drivers present – The device is plugged directly into the host machine USB port (not into the external power...

µFR Nano Online 2.4GHz pairing problem – Android

Problem Nano online is working when pairing is made. But When I turf off Nano Online and then turn it On I have to make pairing again. Other devices after first pairing, connect automatically to the phone without pairing again. Solution This is resolved in the higher firmware versions. Please update your Nano Online to version 2.5.2W, or higher if available. One way to do this is to use the firmware update option at the bottom of the device frontend configuration panel. You can also use the desktop firmware flashing tool available at https://code.d-logic.com/nfc-rfid-reader-sdk/ufr_online-flasher-oneclick.

FTDI device unrecognized on Linux OS

The FTDI device is not recognized by the Linux operating system? To fix this issue, you can perform the following: Check the FTDI drivers’ installation If the Linux OS is unable to recognize the Digital Logic FTDI device, please ensure that the drivers have been properly installed. Follow your operating system’s FTDI driver installation manual and ensure you’ve chosen the appropriate D2XX and VCP drivers for your hardware architecture. Grant USB access to local users Download and run the USB permissions script for Linux to grant the FTDI device access to local users (user group). Blacklist the ftdi_sio and usbserial modules Check if  ftdi_sio and usbserial modules are loaded.  If so, disable them : lsmod –  – Module Size Used by –  – ftdi_sio 26993 0 – – usbserial 21409 1 ftdi_sio sudo rmmod ftdi_sio usbserial sudo rmmod ftdi_sio usbserial To make this change permanent, blacklist modules in the /modprobe.d/ftdi.conf file. Edit ftdi.conf file: sudo vim /etc/modprobe.d/ftdi.conf Add the following code and save the changes: #disable auto load FTDI modules – D-LOGIC blacklist ftdi_sio blacklist usbserial
