pn5180-icode xli x2 read password err

[guangshi]

first get random

detal:

send 09 00 22 b2 04 + UID

rev 00 xx xx(randdom number)

xx Rand[0] Rand[2]

xx Rand[1] Rand[3]

then XOR_password

detal:password 0000 0000(original password)

In the end! Set read password

send 09 00 22 b3 04 +UID +01(read type) +XOR_password

rev 01 0f 

Final reply error.

Are my steps correct?

Hi @guangshi ,

Hope you are doing great the process for this should be :

1. activate the ICODE by sending the inventory command
2. select the ICODE you want with the select command
3. get random number 
4. set password, for the PWD ID you want to use:
   • 01- Read
   • 02 - Write
   • 04 - privacy
   • 08 - Destroy
   • 10 EAS/AFI

you can find a script I just did for you doing the above process for the ICODE SLIX2 and Read PWD.

Hope this information helps.

Have a great day!

BR

Jonathan
