Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hi, I am using an ST25R3911B using the ST25NFC_embedded_library in polling mode on an stm32f103CBT6. In my program, I poll my ST25 and then move on to reading values from arrays of hall sensors (4 arrays of 16 sensors each) a total of 64 sensors. The...
Hello,I'm using the X-NUCLEO-NFC03A1 dev kit with the CR95HF RFID chip. The protocol to talk to the chip I'm using is SPI, and the ISO configured is 15693. I can confirm SPI comms are working as both the ID and ECHO commands work. I also seem to get ...
Hi ST Community,I am an iOS developer exploring communication with your ST25 NFC products. However, I couldn’t find any binary library like a .framework or Swift Package that can be easily integrated into our project.We have attempted to work with th...
I´m developing the PollingTagDetect (for nucleo L746RG) example code into s32k116 microcontroller. I´m only programming the NFC type A (get ID card) feature. There are three main steps, first it´s detect the card type, for this it´s needed to use the...
Hello,I'm currently evaluating the ST25DV chip to implement bidirectional NFC communication with a custom device. So the idea would be to take advantage of the enhanced operating range of ISO 15693 and use the mailbox for direct data exchange.For the...
Hello,I would like to go a bit deep in the inductive wake up function. Unfortunatly seems that i will need to work with delta 1 at least for the moment, but due that it is a battery powered device i need to avoid as much as fake awake when there is n...
In the library functions of arduino, I found that there are only existing functions that receive WiFi, uri, and so on. Now I want to receive picture bytes and store them in an array, but I can't find any built-in functions that are used to receive th...
I use ST25R95 to detect the ST25D tag. I keep the tag on the antenna of the Reader all the time, and some situations have occurred. Hi Even if I place it precisely on it all the time, the tag may not be read probabilistically during detection. Is thi...
Where can I find details on inductive sensor wakeup for the ST25R3916? It's only even mentioned on pages 1 and 11 of the datasheet. My understanding is that inductive wake-up will detect tags only, whereas capacitive will detect other objects like a ...
Hello,I would like to know where I could find the ST25FTM library for Android.Thank you in advance,Best Regards,Selvaraj
