Fork of NDefLib by
NDEF NFC library
This library provides an abstract API to create NDEF formatted messages and records and to read/write them from/to a Type4 NFC Tag.
Implementations
At the moment, the NDEF API is implemented by X_NUCLEO_NFC01A1 and X_NUCLEO_NFC02A1 Dynamic NFC Tag libraries respectively driving the X-NUCLEO-NFC01A1 and X-NUCLEO-NFC02A1 boards.
