A user space application like neard can send type 3 tag commands through the NFC core. Process flow for NFC-F detection is as follow: 1 - The digital stack sends the SENSF_REQ command to the NFC device. 2 - A peer device replies with a SENSF_RES response. 3 - The digital stack notifies the NFC core of the presence of a target in the operation field and passes the target NFCID2. This also adds support for CRC calculation of type CRC-F. The CRC calculation is handled by the digital stack if the NFC device doesn't support it.
