Hello,
I'm developing a System for different NFC types. ISO 14443-A and B works well with ST25R3911B, but I have some trouble getting the ISO 15693 working.
The St25R3911B is set to Sub-carrier Stream-Mode and all settings are done.
I have my dataword (flags, command, mask, makslength, crc16) with LSB and LSb first.
I write this to FIFO. But start transmit with direct Command 'RFID_TRANSMIT_WITHOUT_CRC' / ('RFID_TRANSMIT_WITH_CRC') does not give me any response.
To me it looks like the SOF / EOF ( actually I do not do any SOF / EOF - datasheet tells timing is done in St25R3911B)
is wrong.
Could someone give me a hint ?
Best regards, Nicolai.
Solved! Go to Solution.

Hi Nicolai,
ST25R3911B does not support ISO15693 framing/bit coding decoding. All that must be done inside software. Our demo sources (e.g. x-cube-nfc5 contains the so-called RFAL) show how to perform all the necessary codings, etc.
Regards, Ulysses.
