ISO-DEP protocol
This library is an NFC ISO-DEP protocol implementation for an NFC polling device.
You can use the NFC Reader ST25R3911B library to transmit and receive frames with a tag in NFC-A technology. To start data transfer, a polling device must activate the ISO-DEP protocol by sending the RATS command to the tag. After receiving a response (ATS) from the tag, data can be exchanged.
The ISO-DEP protocol defines three frame types:
I-block - used to convey information to the application layer
R-block - used to carry positive or negative acknowledgments
S-block - used to exchange protocol control information
The library automatically decides which frame type to use and provides full protocol support including error recovery and chaining mechanism.
