Speed Up initializiation

[weoiss1998]

Hello,
I need to be able to detect NFC tags that pass by very quickly. Is there any way I can bypass switching the RF field on and off so that the RF field is always on?

Hi,
I chose to deliberately activate/deactivate the RF field (and reload the ISO15693 protocol into the RF register) on each call to getInventory() as suggested at https://www.nxp.com/docs/en/application-note/AN12650.pdf. This ensures the inventory operation is completely atomic and, in my limited testing, ensured better reliability.

It would be a relatively trivial change to leave the RF field on and just clear the IRQ before activating the transceive command instead, but I'm not sure if this might introduce any other issues. What's your use case?
