Dear 

 

Send command :

Buf[0]=0x0A|BLK;// I-block PCB with CID
BLK ^= 1; // Toggle block number
Buf[1]=CID; // CID
Buf[2]=0x80; // INF:CLA
Buf[3]=0xCA;// INF:INS
Buf[4]=0x00; // INF:P1
Buf[5]=0x66; // INF:P2
Buf[6]=0x00; // INF:Le

 

Recevice command :

size : 64  

data : 1a,0,66,4c,73,4a,6,7,2a,86,48,86,fc,6b,1,60,c,6,a,2a,86,48,86,fc,6b,2,2,1,1,63,9,6,7,2a,86,48,86,fc,6b,3,64,b,6,9,2a,86,48,86,fc,6b,4,2,15,65,b,6,9,2b,85,10,86,48,0,0,

 

Usually, it should be received as follows.

A>> T=0 (4+0000) 80CA0066 00 A<< (0078+2) (25ms) 664C734A06072A864886FC6B01600C060A2A864886FC6B02020101630906 072A864886FC6B03640B06092A864886FC6B040215650B06092B8510864864020103660C060A2B06 0104012A026E0102 9000
