Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hello!Is there any additional information about on how to use on ST25R3916 the bypass mode of internal VDD_RF regulator to be able to a transmitter output current higher than 350 mA (up to 500 mA) supplied from an external source.In ST25R3916 datashe...
I want to use my ST25DV with both I2C and RF interfaces. There is no clear arbitrage between the 2, but the first is served. Moreover, I tested that while I2C is operating in reading and writing bytes in a for loop, the RF can corrupt the data in so...
Hi ST Community,I'm developing an NFC reader for a payment interface and require recommendations for suitable STMicroelectronics chips that are compliant with EMV Level 1 and preferably Level 2Regards
We've had issue with reading NTAG215 cards with some devices, presumably due to the large spread-out antenna, so I'm working on a better understanding of the power output so that we can properly calibrate devices out of manufacturing.Currently, I do ...
I'm trying out the ST25R3911B-DISCO board to evaluate how to read data from multiple 14443A RFID tags. Under the Polling tab I can see all the UIDs for the tags near the board. However, when I go over to the NFC Type 2 tab, if I select "Configuratio...
This is my first time developing a project to read NFC using the ST25R3916B (I bought the Discovery kit for testing). The first thing I did was open CubeMX, but unfortunately, the ST25R3916B is not listed as a supported device for code generation. Th...
I'm needing to get readings from more than one st25r3916 at once for a project using the pc (and java sdk). I'm unsure as to how to do this because"STReader stReader = new STReader(); stReader.connect();"Always connects to the same reader - the only ...
Hi,I use the component ST25R3911B. I'm able to tune some antennas, no issues.But, now I have to use some RF switches to drive several antennas. Unfortunaly the RF switches have a resistor Ron and this drops the output power of the RF reader. The tuni...
Hi, I'm trying to compile NFC Tap for iOS but no luck so far. I've resolved the following issues, by following the advice of other posts on this forum:Add st25sdk header search pathRemove ST25NFCAppClip from buildFix signing and j2objc pathAdd st25s...
Hi thereStarting pointI am currently working on porting our NFC implementation from the ST25R3916 to the ST25R100.We will also replace our current library (Lib-NFC & ST_25r & RFAL) and use the current libraries (RFAL and NDEF) from ST.For the migrati...
