Problems doing updateBinary

Problem doing updateBinary on ST25TA 8K.  I have been able to write using updateBinary only several times.   Most often I get a strange set of bytes.

 

For example:

I send 16 bytes using the NDEF updateBinary command after the NDEF Select file

 

0x2 0x0 0xd6 0x0 0x4 0x10 0x54, 0x77 0x61 0x73 0x62 0x72 0x69 0x6c 0x6c 0x69, 0x67 0x61 0x6e 0x64 0x74 0x68 

 

and I get back

0xf2,0x2,  

 

Which almost fits as a WTX but the bits 7 and 6 are not set.  So it's almost like a deselect?

 

Sometimes I get no response from the card.

 

 

Any insight into this would be greatly appreciated.

 

Thanks,

 

Larry
