Resolved! Setting Area Protection Password In Automated Application?

I would like to start setting area protection passwords on some of these chips. I have a FEIG RFID reader which I can do this through using the ST25PC-NFC Windows Application, but the reader won't fit into the space I need to reach the chip during n...

Resolved! How can we read/write using SPI

Hi,I don't really understand the datasheet of the ST25R3916 IC chip.At page 53, they show an exemple of a direct write command. As I understand, we need to send 1-1-C5-C4-C3-C2-C1-C0. When I check table 13 to see the command code that go for bits C5....

Resolved! ST25R95: What impedance should the antenna be tunned to (16, 27 or 50Ohm)?

Hi,According to the datasheet, the differential impedance between TX1 and TX2 is 27Ohm for 3.3V and 16Ohm for 5V. For the version without EMI filter the matching criteria should: input impedance of the maching circuit is eqault to ST25R95 differentia...

Resolved! SPI interface for STM32L476VG

STM32L476VG is the MCU we are interfacing with ST25R3911B using SPI.what we have understood from some search is that we need RFAL (abstraction layer) to interface with RF HAL.Then once we integrate RFAL and RF HAL in our system workbench(ac6) project...

Resolved! ST25R3911B Collision Resolution returns TIMEOUT_ERR

Hi,I have ported RFAL library to ESP32 platform and have set up proper interrupts for it to function in capacitive wakeup mode.So the issue:We are using RFAL-HL ( higher layer ) in our project ( based on X-Cube-NFC5, but using the latest version of R...

Resolved! Gerber File for ANT7-T-ST25DV04K

Hallo, i Cant find any gerber file for the ​ANT7-T-ST25DV04K.Or can someone tell me what thickness and spacing the antenna has.Many thanks

Resolved! How to configure External power amplifier gain? Internal power amplifier is able to control using txRxCfg.txOutputLevel. How to configure external power amplifier?

Resolved! What's the unit of the variable "deviation" in the evalAPIcommands.c file?

In the evalAPIcommands.c file have the function "reflectedPowerTooHigh()" in the line 907. The goal of that function is to calculate the value of the reflected power and the deviation variable received this value, but don't have a comment in code say...

Resolved! How to get read per second and time stamp of read from ST25RU3993 SDK?

I would like to get the time stamp of read and read per second of one tag. Which is the best way to implement the same using SDK? I would like to get the timestamp of each read as in ST25RU3993 Reader Suite.

Resolved! RSSI Measurement via ST NFC Sensor App

Hello,I am a newbie to the field of RF communication. I am planning to design an antenna using the ST25TV IC. Ultimately, I want to measure the Received Signal Strength Indicator (RSSI) value of the RF communication. I am thinking of using the ST NFC...
