Hi,
The STATUS_NO_ROOM usually tells you that the given array to receive the data is too small.
MFRC522::StatusCode DESFire::PICC_RequestATS(byte *atsBuffer, byte *atsLength)
You are passing a pointer to the atsBuffer, and the length of that buffer as atsLength
. Have you tried with a bigger buffer?
Hi, I am trying to port this desfire library to my ARM MCU. ISO14443 level is finished successfully and I received valid SAK,but when I want to try for RATS,after sending equivalent command to PICC I do not receive any answer and PCD_TransceiveData() method returned STATUS_NO_ROOM ,can any one help me please?
