I'm trying to authenticate to ultralight c and I'm stuck for a few days on the following: (using OK5321)
I'm able to open the generic session:
-> FFA0000703010001
<- 90 00
Authenticate:
->FFA00005080100F30000641A0000
<-00 00 AF 92 11 26 10 8C 1B 8E 3F 90 00
The third step I have tried the following: //random rndbA: 0xA8, 0xAF, 0x3B, 0x25, 0x6C, 0xC7, 0x5E, 0x40
`-> FFA00005180100F30000640078C4B4CC65D91E62AFA8AF3B256CC75E40` //combined the first authenticate result with the rndbA and I get this result:
<- 08 04 00 90 00
Then when I try to read I receive an error.
Am I doing any step wrong?
