ISO 15693 - SOF / EOF for St25R3911B

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.
