When using Send Data in Fast Transfer Mode with ST25DV64KC-DISCO and Android App ST25 Tap, communication will stop with an error if the data size is 200000 bytes.Is there a limit on communication size?
Our application is not related to payment but more around NFC charging and tagging, we'll be using the X-NUCLEO-NFC06A1 (+ NUCLEO-L476RG) combination for the poller.Regarding the listener, we saw that the ST25DVxxKC lineup would be compatible. I'm no...
Hello, I am trying to open a project that can turn on the low power MCU stm32l031 with ANT7-T-25DV64KC while turning high and low periodically for GPO pin of the MCU. I tried many different ways but still not done with any of them (steval code and us...
I'm trying to open a security session with an st25DV tag. I followed the manual and I am sending a message to present the default password (8 x 00h + 09h command + 8 x 00h) using HAL_I2C_Mem_Write. I already looked at the signal with a logic analyzer...
Am in the infancy of a proof-of-concept investigation with ST25DV64. I have been able to do some read/writes with NFC without issue - and am working on the i2c side.We are working with a custom/proprietary system/i2c stack so I don't have much off-th...
Hello,We are now entering the stage of PCB editing and I wanted to ask for your help in the needed calculations and outcome of a printed antenna to be used with the ST25DV04K IC.I have read the app note titled "an2866-how-to-design-a-1356-mhz-customi...
I'm looking for a dev board for the ST25R3916 and I see two options: what would be the difference between the ST25R3916-EMVCO and X-NUCLEO-NFC06A1?I see that the X-NUCLEO-NFC06A1 requires a separate MCU board to connect to, but is that the only diffe...
Hi,Do you have cad for the ST25R3911_MB1325 reference design?
Im trying to get the Pollerexample with the ST25R911b-DISCO working i attached a Picture that shows where.It just stared the programm an had no connection to NFC devices befor.How can i get out of ERR=BUSY ?
Hello, I have an application where we are using a couple of the ST25R3916B in a design but with a different processor. I've looked through the forum posts and gleaned some information here and there, but is there a guide on how to port this library...
