2.2.2 Data Messages
D
ata Messages are used to transport data to either a Remote NFC Endpoint (named RF
Communication in NCI) or to an NFCEE (named NFCEE Communication). NCI defines
Data Packets enabling the segmentation of Data Messages into multiple Packets.
Data Messages can only be exchanged in the context of a Logical Connection. As a result,
a Logical Connection must be established before any Data Messages can be sent. One
Logical Connection, the Static RF Connection, is always established during initialization of
NCI. The Static RF Connection is dedicated to be used for RF Communication. Additional
Logical Connections can be created for RF and/or NFCEE Communication.
Logical Connections provide flow control for Data Messages in the direction from DH to
NFCC.
