Hello everyone,I am working on a project where I need to measure the RSSI value on an NFC reader and NFC tag. The RSSI needs to be the same (or proportional) on both sides and then stored on two microcontrollers on both sides for further processing.I...
Hello, I want to use the ST25R3916 as poller for a WLC project. Is there a firmware library (in best case open source) available which is compliant with the NFC Forum Wireless Charging Specification 2.0?Many thanks for your answers in advance,Kind re...
I use a ST25DV on my board, which communicates through I2C to a uC and through NFC with a smartphone, app developped with Flutter for Android and iOS. Everything works correctly, but sometimes, when I'm writing from Smartphone to ST25DV EEPROM and th...
How to put ST25R3916 in high power transfer mode without communication with NFC tag. for wireless charging?Is amplitude measurement method good for checking the FOD?Does Having tunable capacitor in hardware design and not using those function can cre...
Hi,I am developing new UHF RFID board using ST25RU3993. Can i connect this board to GUI written for ST25RU3993-HPEV eval board?I want to test my board with GUI. I downloaded SDK files for eval board but i am not sure if can connect my board to GUI.B...
Hello,I need to make ST25R3916 read as power efficient as possible. I am searching for documentation, but only this voltage regulator I see (0x2C). Is there any option to change field power of NFC to make a read as power efficient as possible? NFC ta...
We are working on a couple ST25R3916B designs and would like to get some of the latest and greatest reference design, the x-nucleo-nfc08a1. Where can we buy these? I've been watching the distributors for a couple months and haven't seen any which is ...
I am using ST25NFC_Embedded_Lib_ST25R3916_1.4.0 on STM32L5 discovery board with X-NUCLEO-NFC06A1And I have no problem to detect and read ST Tag (always correct), but if I use NXP tag I have super strange behavior.On bare-metal application, it works o...
Hello, In the x-nucleo-nfc08a1 reference design, there is the standard 3 variable cap setup (2 series, 1 parallel) plus also a second set of parallel vari-caps (C307 and the oddly named 4C30). But these are not populated on the board. Should we pop...
