I tried to connect ESP32 and PN7150 plug and play device. I connected in I2C. The serial monitor shows Setup Ok. But when I scan the card nothing happens. Which microcontroller did you use?

Hi @hkarthik97

This library is not ready to work in ESP32 yet, apparently there is not enough buffer for the responses of the PN7150, but welcome your pullrequest, check wire library

this library has been tested on SAMD21, but should work on SMT32, Teensy and similary boards
