Offset on T5577

Please help to explain and how to set the offset value of the T5577 (the below list was read back from the card, there is other card with offset:31, how do I change this 32 to 31).

Thanks

proxmark3> lf t55xx detect
Chip Type : T55x7
Modulation : FSK2a
Bit Rate : 4 - RF/50
Inverted : Yes
Offset : 32
Seq. Term. : No

It’s not a T5577 setting, it’s a Proxmark3 setting:

Thank you :slight_smile: !!!
