ST25 NFC/RFID tags and readers

Hello,I'm trying the X-NUCLEO-NFC08A1 in combination with the NUCLEO-L476RG. I have programmed the demo firmware NFC08A1_PollingTagDetectNDEF.It detects tags but reading distance is very poor.  ( less then 1 cm for small ISO-15693 tags).Is there a GUI tool like the "ST25R3916 Discovery GUI" for this setup?  Is AAT done in the demo firmware?How can i increase power?    

I have been paying attention to the energy collection function of ST25, and I want to make ST25 collect energy to power low-power MCU through NFC. I want to know how this picture is realized, and do you have specific models and instructions?

我最近尝试实现NFC WLC功能，但是X-NUCLEO-NFC07A1中EH的能量输出仅为10mw，无法为NUCLEO-L476RG供电。直到我关注了NFC无线充电功能，却没有找到电池充电芯片的细节，我可以用STBC15实现NFC WLC功能吗？

I want to know the wireless power supply principle of NFC WLC, can I verify the effectiveness of wireless power supply through ST25DV series? Where the listener has a power receiver, how to achieve wireless charging?

I understand that I have exited the NFC WLC function and I currently have X-NUCLEO-NFC07A1. How do I charge the WLC-Listener using the battery charging function shown in the legend?

I need to use NFC to obtain several hundred watts of energy to drive the MCU of L4 to complete other tasks, Can I use ST25 and antenna to achieve this? Can the energy obtained from it be used to charge NFC? Can I use the QI standard provided by ST Company to design and achieve the purpose of NFC energy supply?

Can the NFC WLC shown in the picture be purchased? I need to do the passive test project. Can use NFC to collect energy to power MCU to complete other tests.

Hey, I have the ST25DV64KC-DISCO discovery kit, and I want to program it such that whenever an NFC-enabled mobile phone comes in contact, the phone will connect to a Bluetooth address that will be given inside the firmware code. So in  NFC firmware code in the ndef_demo i have given my mobile  Bluetooth address as I don't have Bluetooth module embedded in my discovery board  and local device name  I have giv my mobile device name now if I go into ble read info in the discovery board menu and try to read it through nfc enabled mobile it giving me the option of pairing with the given local device name but pairing is not happening now how to program it so that it will pair the other nfc enabled phone with the given Bluetooth address when try to read it through nfc tag .I have also adding the part of the code I am changing for this problem any solution from you will be appreciated    #include "ndef_demo.h" #include "string.h" #include "stdlib.h"

I noticed that there is the ST25DV SDK for Java, but is there any package yet for iOS devices? I am currently using Flutter and I can use the Java SDK for Android, but there is no package for the iOS devices. If currently there is no package for iOS yet, is there any plans in the future to create a package in Swift or Objective C? Thank you before!

Hello, i'm starting to work with a ST25DV64 device and at beginning the read command of UID (Address 0x0018) just work fine. And i get the UID of the chip.But after implement some write commands (password,fast transfer mode, enable gpo,...) the chip now only return NACK after reading the UID. I removed all other commands, but reading of UID only return NACK.What happens to the chip? Is he locked? And how can i get him unlocked? Or is maybe the chip deadlocked?We are testing with the ST board ANT7-T-ST25DV64KC and we put some pull-up resistors with 10k.I have now 3 boards that are all "locked".  

Hello Everyone,I'm developing a WPF(.NET Framework) application in which i'm using the CR95HF.dll also I'm using the CR95HF Demo Board to read some ICs like M24LRxxE and ST25DVxxKI've made some readings using VB.NET since all the information I found is for VB. and it works fine for me because I've read some tags.Unfortunately my final application is based on C#, so my question is if there are some code samples or some docs that give instructions on how to use C# to make the connections.or how to declare those kind of functions to be able to work using C#Public Declare Function CR95HFDLL_USBconnect Lib "CR95HF.dll" () As LongPublic Declare Function CR95HFDll_Idn Lib "CR95HF.dll" (ByVal mystring As String) As LongPublic Declare Function CR95HFDll_SendReceive Lib "CR95HF.dll" (ByVal mycmdstring As String, ByVal mystring As String) As LongPublic Declare Function CR95HFDll_STCmd Lib "CR95HF.dll" (ByVal mycmdstring As String, ByVal mystring As String) As Long

Hi,I'm using an ST25DV04KC tag with the STM32L476 microcontroller as the host. I can write and read from the tag without issues through I2C. However, I'd like to inquire about the feasibility of gradually adding data to an existing NDEF message stored in the tag's memory.I looked into some older topics, and I saw that this might be implemented in future versions. Has this been implemented in any library?I see that it is possible by completely rewriting the message with the new aggregated data. However, this would wear down the memory unnecessarily. So, I would like to simply add the new data to the end of the previous message. I know that to achieve this, I will need to modify the NDEF header to identify these new data. I'd like to know if I should implement this myself or if ST already provides this feature in any library.

The existing version of the ST25RU3993 Reader Suite (ST25RU3993_GUI_v1_8_6_EVAL) is not supporting the C Library files (from en.STSW-ST25RU-CLIB) that are currently available. Please inform by when the new version is releasing.

Hello,I have a jewelry brand and i´ve been thinking about making smart jewelry with NFC technology. I found a 5x5mm NFC chip but it´s still too big for fine jewelry; i read somewhere in a forum that i can find here the smallest NFC chip (2x3mm), does that chip exist (I think is in the ST25T series)? or which one do you recommend for that purpose?.Thank you in advance.

Hello.I have two nucleo boards, first one is NUCLEO-L476RG other one is NUCLEO-F767ZIAnd I have one X-NUCLEO-NFC08A1 (ST25R3916B).I want to use NFC08A1 on NUCLEO-F767ZI (or other board).I have started to create new project on STM32CubeIDE.And I copied sample codes from NFC08A1 EXAMPLE PROJECT.I modified code to avoid error and warning. and It is done.But, The code that I created is not working.sadly, I do not know why. May I get simple code for ST25R3916B? Example code privided from ST is very complicated.I am gonna attach my source codes and provided example codes from ST.Please help me!! :crying_face: my codehttps://drive.google.com/file/d/1UCDHrzmj59AH6B0b1C6I15UvrhaD2Ykm/view?usp=drive_link st codehttps://drive.google.com/file/d/1dEmPlHNlsBykh4ErHa3s9A3vB4GcDaa1/view?usp=drive_link

I am thinking if it is possible to use a reader to read out the values through the ST25DV(Powered mcu by the Veh from ST25dv). Therefore, I bought x-nucelo-NFC7 and stm32l4, and I hope to power L4 through EH energy, but the energy obtained through NFC makes the L4 power lamp light up, but the MCU does not run successfully. What should I do?

Hi we are developing a product in lighting with STM32MCU and ST25 NFC Chip.We are planning to develop an customer app for our products with certain parameters that we can have the variables through NFC .One of my colleague recommended the app can be developed using ST25 NFC App(SDK).Is it possible to use the app for our products.Just as a new joinee a doubt about the idea or else we have to develop it with different IDE (eg.Eclipse)to have it as exclusive for our product.

Hi there,we are currently using st25r3911b in our project with F32F302CC.I've ported the example project from here, notice that the latest version is v2.0.0:https://www.st.com/en/embedded-software/x-cube-nfc5.html#st-get-softwareNow I found out, that v.2.0.0 isn't the latest version anymore, when looking at your website:https://www.st.com/en/nfc/st25r3911b.html#tools-softwareSo I now tried to upgrade to the latest firmware "V2.8.0 / 14-Dez-2022" (mentioned link), and tried following examples as an upgrade: "STSW-ST25RFAL001" and "STSW-STM8-NFC5".But it seems there are critical changes between v.2.0.0 and v.2.8.0, meaning such things as "utils.h" is now named "rfal_utils.h" but that't the small problem. It seems there are a lot more changes (definitions), so it is too complicated to easily upgrade here. It also seems that the "ST25RFAL001" example has some missing header files?!So my question is:Can you please also provide the latest version "v.2.8.0" for the x-cube-nfc5? Thanks in

I wonder if STSW-ST25R-LIB supports ST25R3918 or if there is a plan for future support?As well if there is any RFAL library that supports ST25R3918?

Figure 1 of the ST25R3918 spec shows an AGD pin in addition to the GND_A pin.   It is connected to VSS through two capacitors.  I don't see this pin on the Table 1 pin assignments.  What is the intention?Thanks,Ted

Has anyone implemented or does ST provides a library where the NDEF records can be appended or chained together for data logging such as long term sensor data etc without overwriting the old records? Looking at the current NDEF library of the ST25DV it does not seem to do so. Does anyone has any workaround or solution for this?Thanks

Hello Support team,We are working on the ST25R3916 NFC-based device and we are getting a lower range for passive tag type 5 is around ~10mm. So, we want to increase the detection range through.Is it possible to increase the NFC tag detection range through the DPO feature?If you have any reference code or document then please provide us.Thanks & Regards,Chintan Patel

Hey, So I've encountered an issue with STSW-ST25PC001 software. I notice that it doesn't work on windows 11 machines, the install process works fine. But once it's finished the application opens then closes immediately. I also tried to run the program as admin, and it opens and crashes instantly. Any solution on how to get STSW-ST25PC001 to run on windows 11?

Hi!I have a case where I want to read all tags in area one by one. Issue is that if I call `HLTA` command, even after selecting a tag, all tags in area go to sleep. Is this intended behavior in ISO 14443A protocol or I am doing something wrong?Hlta -> https://github.com/jspngh/st25r3911b/blob/master/src/lib.rs#L275Select -> https://github.com/xpresshd/st25r3911b/blob/master/src/lib.rs#L575Thanks!
