As specified in the NCI spec, NFC Execution Environment (NFCEE) is an environment where NFC applications are executed (e.g. secure element). NCI provides features to allow DH to NFCEE communication. NCI therefore includes methods to discover and enumerate connected NFCEEs and the Interfaces they support, and to establish connections between DH and NFCEE Interfaces. A logical connection is a connection between the Device Host (DH) and the NFC Controller (NFCC) that is used for communication towards a target, either NFCEE or Remote NFC Endpoint. More than one Logical Connection MAY exist to the same target. > Out of curiosity, is this NCI HW of yours based on the TRF7970A > chipset ? No, it's a new TI combo device, not in the market yet.
