hello,

       Recently, I fond that PN532 can't find some M1 card.the problem card of  UID 'length  is  4 bytes,and the first byte is 0x88 when I use pn512 device test . Just  to be  equal to the CT, but the UID is 4 bytes can  compute the ATQA  to reach. But the pn532 return no cards. I guess  that PN532 deal the first byte 0x88 as equal to CT,then consider the UID  more than  4 bytes,  then  return  no card.

    can you test this situation?  And sove it
