The configuration password (00, 00, 00, 00) and zone 1 password (00, 00, 00, 00, 00, 00, 00) of the tag have been confirmed using ST25R3911B-DiSCO evaluation version

Hi ,

The error code 5 is not a value that the ST25TV02K PresentPassword RF command is returning.

So we would need to know which subfunction of the rfalST25xVPollerPresentPassword is generating this error.

Also could you please provide the values of A1SS and A2SS registers?

Thanks & regards

JP

zone 1 password is (00, 00, 00, 00, 00, 00, 00，00) --8 bytes

Hi,

error code is ERR_REQUEST. I presume this is translated/produced by rfalNfcvParseError().

Please inspect inside rfalST25xVPollerPresentPassword() the structure rfalNfcvGenericRes res; which should give you the error code directly from the tag and thus more insights.

Best Regards, Ulysses

Hi,

for ST25TV02K/ST25TV512 products password length is different from one used in ST25DV series. See product datasheet §6.4.21 Present Password: Password is 32-bit wide for all passwords, except for Area 1 [...].

Just change line 19 of your code to

uint8_t pwd[4]={0x00,0x00,0x00,0x00}; //BT: for ST25TV02K, pwd is 4 bytes

Thanks, the problem still exists, and the output error message is the same。

After tracking, the screenshot is as follows

ST25PC-NFC software can help me to confirmation �?Password configuration is （00，00，00，00）“

Hi,

the pwdNum is incorrect. If you want to use the configuration password, pwdNum should be 3h.

See datasheet §6.4.21 Present Password::

Password number (00h = Password KILL or UNTRACEABLE, 0x01 = PWD_A1, 0x02 = PWD_A2, 0x03 = PWD_CFG, other = Error)

Hi,

err = 10 means "the password number is incorrect "

See datasheet §6.4.21 Present Password:

Response parameter:

Error code as Error_flag is set:

02h: command not recognized
03h: command option not supported
0Fh: the present password is incorrect
10h: the password number is incorrect
