Hello, i'm currently working with NT3H2111 tag. I our use case, tags will be exposed to brute fore attack, so i have set PWD,PACK and AUTHLIM value. When AUTHLIM number of invalid password is reached, even a valid password cannot unlock the device.
But, in my case i want (via i2c) to re-enable (after one hours) that a valid password unlock the device.
I have try to re-set PWD,PACK and AUTHLIM to others value and then set again to valid value but it didn't work.
The only methods working i have foudn to reset NEG_AUTH_REACHED seem to be setting AUTHLIM=0 and sending valid password via NFC.
I can't use this solutions in final product.
Can you tell me is there's another way to reset internal counter or NEG_AUTH_REACHED bit via I2C access only ?
Thanks for your idea
