I am programming an app to power an MCU via NFC. The MCU is connected to a sensor, and the sensor data continuously updates to the NFC chip. However, I'm facing an issue where my app only reads a single value until I move the phone away and bring it back to sense again, which then updates to a new value. In many papers, I've seen NFC chips similar to mine (Natgi2c) continuously update sensor values to the app without needing to move the phone away and back again. Why is this happening? Is it a problem with how the app is programmed or with the chip itself?
Thank you
Yes, the scenario you describe is achievable, and NXP has relevant routines for you to refer to.
