Can not read NFC card on PN7150

My PN7150 can read most NFC cards.

 

I got a  ISO 14443-A NFC card.

ACOS3 Microprocessor Card (Contactless) | ACS 

 

I can receive i2c data from PN7150, but can not parse its UID and return Undetermined target.

 

Here is the i2c log 

====================================================

<< 61 03 0e
<< 61 03 0e 01 05 00 09 04 00 04 b0 8c d0 72

 

<< 61 03 0e
<< 61 03 0e 02 04 00 09 04 00 04 b0 8c d0 72

 

<< 61 03 0e
<< 61 03 0e 03 02 00 09 04 00 04 b0 8c d0 72

 

>> 21 04 03 01 05 03

 

<< 41 04 01
<< 41

 

- POLL MODE: Undetermined target
>> 21 06 01 01

 

<< 41 06 01
<< 41

 

CARD REMOVED

====================================================

 

I used NXP Software package is SW3241.zip

I traced the code in NxpNci.c 

 

It seem did not have case when i2c receive is  

Answer[0] == 0x61

Answer[1] == 0x03

in "bool NxpNci_WaitForDiscoveryNotification(NxpNci_RfIntf_t *pRfIntf)"

 

 

Any idea for it  ?
