Hello SG3,

In case the app performs a deselect sequence for T4T case then the card emulations should trigger such by returning RFAL_ERR_SLEEP_REQ.

Hi,

I was able to detect when the mobile is removed when it returns the error LINK_LOSS.

 

I am still trying to figurate out how to know that the communication has end. I ma using the app NFC tools.
