We are working with ST25RU3993 eval board and controlling it from linux based STUHFL C code base.Could you please suggest best config for reading weakest tags with ST25RU3993 using C code base.
I thought I could send custom commands to the ST25DV Tag by using the NFC Tap app. Is that possible?In the app there are two fields when I chose "Custom":1) Custom Command. There I enter "AC", to Read Message (mailbox).2) Data: what to enter here? Ca...
I'm considering a ST25R3916B design to emulate a 14443 A&B device and preferably be powered by the field. It's not at all clear from the datasheet what the current draw is when not operating in an Active mode - there's a big gap between 4uA in Initi...
