Hi I am trying to implement a custom ISO/IEC 15693 command called "Fast Read Unlimited Blocks" command for the Fujitsu Tag MB89R118C (attached the datasheet). This command allows reading all 256 memory block or 2048 bytes on the Tag's memory in one t...

I ran into the same issue of the read multiple registers being seen as 2 SPItransactions. I also have a SPI driver that manages the CS pin. What I did was to let the SPI manage the CS pin as well as left the platformSpiSelect() and platformSpiDeselec...

Hi @CDowd.1 ,You need to call the rfal lib function st25r3911Isr() (in st25r3911_interrupt.c) in your ISR for the INT pin from ST25R3911B to your MCU. I was missing that. Your ST25R is setting the INT high correctly, your ISR for the INT pin then ne...

Hi Ulysses,I am seeing the exact same issue. I checked the SPI signals on the logic analyzer and I do see an interrupt set on the INT pin after sending the field ON command is sent in the st25r3911PerformCollisionAvoidance() routine. See attached. H...

Getting ERR_NOMEM when implementing custom "Fast Read Unlimited Blocks Command " ISO/IEC15693 command with ST25R3911B and MB89R118C Fujitsu Tag, to read 256 memory blocks/ 2048 bytes in one transaction.

Where can I find an updated platform.h to go with the latest version of RFAL library (en.STSW-ST25RFAL001, v2.2.0/22-May-2020)

Is it possible to use non-blocking SPI drivers to setup RFID comms using the ST25R3911B and STM32L496 MCU

What does a Security Status = 63 mean when reading a single block from a RFID tag using the ST25R3911B and ISO-15693?
