H A Dnfc-hci.rst2 HCI backend for NFC Core
11 The HCI layer implements much of the ETSI TS 102 622 V10.2.0 specification. It
12 enables easy writing of HCI-based NFC drivers. The HCI layer runs as an NFC Core
14 to HCI commands and events.
16 HCI chapter
19 HCI registers as an nfc device with NFC Core. Requests coming from userspace are
20 routed through netlink sockets to NFC Core and then to HCI. From this point,
21 they are translated in a sequence of HCI commands sent to the HCI layer in the
24 from HCI Rx context).
25 HCI events can also be received from the host controller. They will be handled

22 In the normal (HCI) mode the protocol used is derived from the ETSI
23 HCI specification. The firmware is updated using a specific protocol,
24 which is different from HCI.
26 HCI messages consist of an eight bit header and the message body. The
27 header contains the message length. Maximum size for an HCI message is
