ST25R3916 How to set it into 14443-A emulation mode and send/receive APDU ?

[Stasevich]

Hi everyone !

After successfully launched ST25R3911 (in 14443-A smart card reader mode) without RFAL , using only analysis of dialog on ST25R3911B-DISCO there was a need to implement an 14443-A emulator based on ST25R3916.

With the DISCO everything is easy : logic analyzer, datasheet, and a week to learn and reproduce control commands for ST. The result is a sequence of instructions and register values to implement read mode, sleep mode and so on.

ST25R3916 it’s difficult here, let’s say I’m not friends with RFAL in the context of integration into my project and I don't have access to something like DISCO for 3916.

The Q is : in which document can I find a sequence of commands using RFAL or register values / direct commands and algorithm for implementing the emulation mode ?

Hi,

Your attempted read of FIFO status register actually ends up as a write! The MOSI byte for reading FIFO status register needs to be 5Eh. By using 1Eh you are performing a write (to a read-only register).
