USB-connected µFR Nano Online NFC RFID Reader Writer on the Raspberry Pi

USB-connected µFR Nano Online NFC RFID Reader Writer on the Raspberry Pi To connect and run the µFR Nano Online reader plugged into the Raspberry Pi USB port, follow the instructions below: 1) USB-CONNECTED µFR NANO ONLINE NFC READER INSTALLATION All µFR series devices require FTDI drivers for USB communication. This also applies to the µFR Nano Online NFC reader if it is used as a standard USB device. If you have no FTDI drivers installed on your installed Raspberry Pi, please follow the manual for the FTDI drivers installed on the Linux-based platforms. This article is also available in our Knowledge Base. Important notice: Before you proceed with the µFR Nano Online implementation, make sure you grant the USB PORT access permission to the local user (the script is available in our GitLab projects repository). Once you have the FTDI drivers installed with your USB-connected NFC reader, you will be able to open the port and establish communication with the device by the ReaderOpen function provided by the ufr library. Important notice: The recommended library for the Raspberry Pi is the 64-bit aarch64. However, there are some known problems with aarch64 on a Raspberry Pi 4 with 8 GB...

µFR Series devices installation on Linux distributions

Is there any simple console application example for continuous reading?

Is there any SDK for C # .NET Core 3.1?

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  

Can µFR devices be used in OpenWRT projects?

OpenWRT (OPEN Wireless Router) is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The application of µFR Series devices in OpenWRT projects has not yet been tested. Since these devices have full support for Linux and Linx based environments (eg Raspberry Pi, BeagleBone, etc), the implementation on OpenWRT should theoretically be easy to achieve. Even though the MIPS libraries were not compiled yet, the ARM and x86 libraries can be used for these projects’ development. Find out more on https://dev.openwrt.org/wiki/platforms. 

Is the library for ARM architecture (for Linux on the Raspberry Pi) available?

Among others, µFR Series SDK includes the libraries for the ARM processors. Please, check all available support below. µFR Series libraries µFR Series libraries are available for the following platforms: Windows 32 and 64 bit (static and dynamic) Windows ARM Linux 32 and 64 bit (dynamic only) Linux ARM and ARM-HF (dynamic only) Mac OSX 32 and 64 bit (dynamic only) iOS 64 bit (static only).
