STUHFL tag write password length 8 digit

[Sandhu]

Is there any limitation for tag write password length? Because in C demo, its limited the length of password as 4. But our tag is protected with 8 digit password. Would like to know how to handle the 8 digit password?

is it only the modification of 'STUHFL_D_PASSWORD_LEN' to make it compatible to 8 bit password? What will be the effect of changing 'STUHFL_D_PASSWORD_LEN' to 8?

Hi Sandhu,

could you share the exact tag that you are looking at? Also what do you mean by 8 digits/bits? Passwords in Gen2 are 4 bytes long, which in typical hex/base16 representation will be displayed as 8 hex digits.
