HALT only single tag in field

RMuiz.1 · ‎2023-08-17

Hi!

I have a case where I want to read all tags in area one by one. Issue is that if I call `HLTA` command, even after selecting a tag, all tags in area go to sleep. Is this intended behavior in ISO 14443A protocol or I am doing something wrong?

Hlta -> https://github.com/jspngh/st25r3911b/blob/master/src/lib.rs#L275
Select -> https://github.com/xpresshd/st25r3911b/blob/master/src/lib.rs#L575

Thanks!

1. Yes
2. Yes

Now with field restart before WUPA it works as I intended.

Currently I send `Reset` command to turn off field. I was wondering if there is a cleaner way to do it. No field off commands? :)

Hi,

our RFAL rfalFieldOff API just clears the rx_en and tx_en bits in the Operation control register.
