Hi everyone,Has anyone experienced issues with the NFC tag becoming unreachable via I2C? During debugging, I noticed a HAL timeout when waiting for the tag's response after setting the address to the EEPROM, static, or dynamic register. Additionally,...
Hi ST team,We’re using the ST25R3918 in a low-power BLE+NFC product. During testing, we noticed unexpected ~10 µA additional current draw when the chip was in Power-Down mode (with all VDD rails active), despite expecting ~1–2 µA per the datasheet.Af...
Hello,I’m currently working on NFC detection using the ST25R3917 with Felica.My system configuration is as follows:PC Application ⇔ USB to I2C ⇔ ST25R3917I’m running RFAL in the PC application and have extended rfal_platform.c to control the USB to I...
Hi there, I have a brand new STEVAL-25R3916B main board for my project which require NFC capabilities and Bluetooth (BLE) v5.x conectivity. According the user guide [User guide - Page 5] on the rear side of the board there is room for a bluethooth mo...
We are currently seeking layout recommendations for the ST25R3916 and ST25R3918 chips.On the Transmitter Side:ST25R3916B → Power Amplifier → Matching Circuit → AntennaOn the Reciever Side:Antenna → Matching Circuit →Power Harvester → ST25R3918The imp...
Hello,I would like to confirm the correct procedure for measuring antenna impedance using a NanoVNA. The chip under test is the ST25R3916.I came across the post titled "How to Measure Antenna Parameters According to AN4974 with NanoVNA," which was ve...
I am currently working on a project that involves reading NFC tags using the NFC X-NUCLEO-NFC08A1 extension, which utilizes the ST25R3916 NFC reader connected to an STM32 Nucleo-G0B1RE platform.Having completed the hardware interfacing for SPI commun...
Hi, I am using a customer board with h7. Similarly, I want to read a simple nfc card using the st25r3916 chip. For this, I made the necessary adjustments using RFAL libraries without using the cubeMx ready package.I have completed the necessary hardw...
Hi, We are developing a prototype containing a st25r3916b nfc reader. When the prototype is idle it goes into sleep mode and wakes up through the wakeup function. When we actively poll for a card from our MCU we can read a UID from a distance of abou...
Hi,I am currently working with the X-NUCLEO-NFC08A1 as reader another PCB with a stm32 microcontroller and a ST25DV04K tag. I don't have access to the source code of the board with the tag but i know the used protocol to interact with it.I got everyt...
