Hi am using ST25R3911B DISCOVERY Board, and I am using ISO15693 Single read and write function.but this function not work properly and i found an err code after execution the code.the value not to be read and write properly. but  st25r3911WriteTestRegister(res,value);this function work properly for read and write.Do u have any suggestion regarding this .

Hi,

I was expecting that led A and LED B ON after succesive read and write in tag. but here both led's are off.and also confused with RFAL_NFCV_REQ_FLAG_DEFAULT VALUE, is it possible to use here a particular flag value like 0x02.
