Hello,I've changed the impedance matching network on the NFC06A1 such that the system is resonant at 13.56MHz with an impedance of 2.6 ohms. The reader is in 5V mode with the regulator display register measuring 4.3V at VDD_RF. I have set the output ...
Hi ST,We are trying to integrate a ST25ru3993 with a new µC. We managed to detect and list tags using inventoryGen2() command, but we are struggling with the gen2ReadFromTag() one:In the doxygen embedded in gen2.h code, we can see the following examp...
I am having problems with the ANT7-ST25DV04K module. What happens is that when I bring the mobile close to the module to read it, the NFC of the mobile is activated and deactivated all the time and never finishes reading the card. I'm using the ST25 ...
Hello ST,We are working with the ST25RU3993-HPEV board to evaluate the RFID chip.We have performed measurement of the output level on the antenna port and below are the obtained results:For the internal PA:Output level set using ST GUI / Expected out...
How do I enter a password on the NFC Tap iOS app when the keyboard covers the action buttons?I'm trying to password protect a ST25TA02KB using NFT Tap for iOS, and having some difficulty. First, it's giving me a, "This is not a type 4A tag" error. If...
Hi,I have a project where we use the STM32WB55 with the ST25R3911B as NFC module for OOB pairing.I couldn't find any example for OOB pairing flow.My start point is the p2p_server example and I can see there are:BleApplicationContext.BleApplicationCon...
Hi eveyone,I need to use the CR95HF.dll library on a VB.NET application but when i try insert on the project i get an error.I think this library is VB compatible only but i dont sure about this.Maybe anyone know how to port this library to be used on...
Is there a register to set the outputpower on the ST25R3916 like on a Texas Instruments RFID transceiver? Or is the output power entierly controlled by the DPO?
