Open the RF security session on Android device
Hi,
we are trying to using the ST25DV64K to implement the reading and writing data via RF between the ST25DV64K and Android device.
The area 3 is protected by RF password 3 with default password .
Tried to use the below code to open the RF security session but always return �(byte)0x01�. Could you advise ?
It would be appreciated if the sample code of reading and writing the data on the protected Area is also provided.
Thanks.
public static byte
[]SendPresentPasswordCommand
(Tag myTag, byte
PasswordNumber, byte
[] PasswordData,
DataDevice ma){byte
[] response =new byte
[] {(byte
)0xFF
};
byte
[] PresentPasswordFrame;
PresentPasswordFrame =
new byte
[]{(byte
)0x02
,
(byte
)0xB3
,
(byte
)0x02
,
PasswordNumber,
PasswordData[0
],
PasswordData[1
],
PasswordData[2
],
PasswordData[3
]};
PresentPasswordFrame =
new byte
[]{(byte
)0x02
,
(byte
)0xB3
,
(byte
)0x02
,
(byte
)0x03
,
(byte
)0x00
,
(byte
)0x00
,
(byte
)0x00
,
(byte
)0x00
};
int
errorOccured =1
;
while
(errorOccured !=0
) {try
{ NfcV nfcvTag = NfcV.
get
(myTag);
nfcvTag.close()
;
nfcvTag.connect()
;
response = nfcvTag.transceive(PresentPasswordFrame)
;
if
(response[0
] == (byte
)0x00
|| response[0
] == (byte
)0x01
)//response 01 = error sent back by tag (new Android 4.2.2) or BC
{ errorOccured =
0
;
//Used for DEBUG :
} }
catch
(Exception e) { errorOccured++;
//Used for DEBUG :
if
(errorOccured ==2
) {//Used for DEBUG :
//Used for DEBUG :
return
response;
} } }
return
response;
