uFR Zero Online – Unified Firmware Package System

µFR Zero Online – Unified Firmware Package System Introduction With the release of ESP32 firmware version 3.0.82, µFR Zero Online devices have adopted a unified firmware package system. This change simplifies firmware management by allowing developers to update both the ESP32 main controller and the NFC reader-writer in a single process. Instead of handling separate firmware updates, you now select from precompiled firmware packages that ensure both components always run mutually compatible versions. This article explains how the new system works, what package types are available, and how to resolve common issues when working with firmware packages. How Firmware Packages Work When you click “Check for Updates” in the device frontend: Individual firmware versions are no longer listed. Instead, you will see packages named in the format: Zero_Online_YYYYMMDD The date indicates when the package was created. A newer date corresponds to a newer firmware version. Once selected, the package automatically installs the correct versions of: The ESP32 main unit firmware The NFC reader firmware This ensures both parts of the device run on compatible builds. Package Variants Three types of firmware packages are available: Zero_Online_YYYYMMDD – the standard package for most devices. Zero_Online_Lite_YYYYMMDD – for Lite variants of µFR Zero...

µFR Reader Writer on macOS – FTDI drivers and communication permissions tips

µFR Reader Writer on macOS FTDI drivers and communication permissions tips *NOTICE: Applicable only to old macOS versions and legacy µFR devices. Do not use for the µFR Zero series and recent macOS releases! macOS has a bit different structure than Linux so communication with the reader cannot be enabled with a simple script available for Linux users. Enabling the communication between the software and the USB-connected reader varies depending on the macOS version. The OS versions from Mavericks (version 10.9) and above already have the AppleUSBFTDI driver. The interface is matched to the FTDI kext, which in turn creates a BSD serial port for use at the application layer. The application opens the serial port to communicate with the hardware. On the other hand, the USB-connected µFR devices implement user client drivers to communicate directly with the device from the user space (FTDI D2XX Driver). Therefore, the presence of the AppleUSBFTDI kext might affect communication with the software. Software applications may fail to open a connection with the hardware because IOKit already has matched the AppleUSBFTDI driver to the device. The solution in this instance is to unload the AppleUSBFTDI drivers before installing the FTDI D2XX. You may find...

Long-distance connected reader – Base HD

A Long-distance connected reader refers to a device with the capability to be connected to the host by significantly long cables. Some projects may require the devices to be placed at a significant distance from the host/PC/server, etc. For these cases, we recommend using the Base HD device. These devices can be connected on a total distance of 1.5 km of standard UTP cable Cat5e or higher. They use USB to RS485 and vice versa signal conversion, transparent to the end-user. For the configurations closer than 320 meters, the additional power is not necessary. One device can be powered using just a USB from its host. For longer distances, the additional power supply is a must, due to voltage drop on long cable runs. For more details, please contact our technical support.  

Firmware update & upgrade

Digital Logic provides a fast and easy firmware upgrade in just a few steps. We release new firmware versions frequently. Once we have a new release, we provide a tool for a simple firmware upgrade. Firmware flashing tools Download the flashing tools for your device: ufr-flasher-oneclick – One-Click Programmer for µFR Series readers (devices with serial number: UF:00XXXX, UN:00XXXX and UC:00XXXX) basehd-flasher-oneclick – One-Click Programmer for BaseHD Series readers ufr_plus-flasher-oneclick – One-Click Programmer for µFR Plus Series readers (devices with serial numbers: UF:1XXXXX and UN:1XXXXX) ufr_online-flasher-oneclick – One-Click Programmer for µFR Online Series readers.  The same firmware version applies to all devices of the assigned series. The software is smart enough to recognize the attached device model and accomplish the firmware upgrade.

What is the purpose of RTC and EEPROM upgrade for µFR device?

Embedded RTC Some projects require accurate current time instead of relying on the PC system time or the host time. Accepting the time from these sources bears a potential risk because it can be changed on purpose, causing a potential system vulnerability and security issues. For this reason, the readers’ built-in RTC module ensures accurate timekeeping without any influence from its environment. The time set for the reader can be modified with password authentication only. Embedded EEPROM User EEPROM is part of non-volatile memory for storing small amounts of important data, such as license keys and similar. It is also a password-protected area: a valid password is required for writing data into that area. The data reading is also available with a provided password only. This feature is very convenient for the device integration with the custom made software, or another complex project.

What is the hardware AES128 encryption?

About encryption processes Communication with high-security cards, e.g. DESFire, which uses cryptographic protocols (DES, 3DES, AES), relies on cryptographic algorithms. This means that there are a lot of intensive calculations and repetitions. In case this is done in a library or software, the communication channel remains the security weak point. Otherwise, if this takes place in hardware, the entire cryptography is secure. Digital Logic high-security solution Given the above security weaknesses, Digital Logic has applied a special method of storing and processing keys within the hardware. All calculations, key exchange, key storage, and more are performed in the hardware (reader). This means that secret keys do not come out of the device when the reader and host communicate. For this feature, Digital Logic uses the AES128 crypto algorithm for DESFire cards/tags. The keys are securely stored in the reader and cannot be compromised. It was a logical solution because AES128 is quite fast and efficient compared to DES and 3DES which still perform processes externally by the software.

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.

Can Digital Logic devices be integrated into other RFID door access control systems and use previously programmed cards?

The possibility to successfully replace some other manufacturer hardware with Digital Logic devices in already installed RFID door access control systems depends on many factors. To make sure that new hardware will be fully functional with the previously programmed cards or tags, it is necessary to check if the new devices support those card/tag type, but also to have insight into the current system structure, security Keys, encryption type, etc. Depending on the system, the hardware replacement may be easy, but also impossible to accomplish. Also, technical and programming knowledge is a must.
