Hello @ujwal_kumar_N_L

Hope you are doing well.

Discovery Loop from the NFC reader library may only be designed for POLL mode.

Perhaps you can take a look at the LPCD example from the NFC reader library (NfcrdlibTst12_Rc663Lpcd) and refer to the following articles:

Hi,

NfcrdlibTst12_Rc663Lpcd example project is included in the NFC Reader Library. You can download the library corresponding to your device from the Downloads section of the webpage:
