Abstract
Aspects relate to improved mechanisms for updating parameter values for communications between a DH and a remote NFC endpoint. In one example, a DH associated with a NFC device may be configured to determine that one or more parameter values included in a parameter selection request message are different than one or more corresponding parameter values used during discovery of a remote NFC endpoint using a frame RF interface, and communicate the parameter values to a NFC Controller using a parameter update message. A NFCC associated with a NFC device may be configured to receive, using a NFC-DEP interface, a parameter selection request message including one or more parameters, determine to implement one or more parameter changes based on the received one or more parameters, and communicate an activation message to a DH indicating values to which the NFC Controller changed the one or more parameter values.
