Hi,

Do you mean:

• Your system is based on a dynamic tag communicating with a microcontroller (MCU) over I²C.
• Your system is woken up when entering the phone's NFC field, that is, your system is powered by the harvested energy.
• Reading the tag by the phone triggers an action on the phone.

As the title of your post refers to ST25R3916B, do you mean your system is based on a reader in Card Emulation mode?

Feel free to provide more information, such as which tag or which MCU is used or whether Card Emulation is use. 

Usually, iPhone reacts when the tag memory contains an NDEF URI message. Using the NFC Tap iOS app, NDEF messages can be written to and read from the tag memory. Once an NDEF message (e.g., containing a URI) is written to the tag memory, you can tap the tag and observe how the iPhone handles it.

If an ST25R3916B is being used in Card Emulation mode rather than a physical tag, the X-CUBE-NFC6 provides a demo that includes Card Emulation. Just enable the DEMO_CARD_EMULATION_ONLY compilation flag. A default URI (st.com) is provided in the emulated memory.
