No, the NPP server is *always* the recipient of NDEF messages. I.e. each Nexus S has a NPP server running in the background that listens for incoming NDEF messages from *other phones*. As soon as an NDEF message is received, this message is dispatched through the NFC intent dispatching architecture. The NPP client is *always* the sender of NDEF messages. Thus, whenever you invoke enableForegroundNdefPush(), you feed the client with an NDEF message. As soon as another phone supporting LLCP/NPP comes into range, the NPP client sends its current NDEF message to the *other phone* across the NFC peer-to-peer link. > Can i first delivered in one Nexus S phone NDEF_DISCOVERED intent,and > received the > NDEF messages.Then use the enableForegroundNdefPush to throw the > messages back. > Can i use this to alternate the questions how to get reponses above? Sorry, I didn't quite understand what you tried to ask with these questions. br, Michael -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
