[android-developers] NFC bidirecional communication with Android ICS using two Nexus S
I am working on my Computer Science’s thesis about NFC and I’m facing some unexpected difficulties in Android ICS. My application basically needs to implement these steps (using two Nexus S): 1 – Phone one sends a NDEF message to the phone two; 2 –The phone two receives and process this message and returns a new message to the phone one; 3 – The phone one receives and stores this message. The problem is that I can only send one message by tap and along with it, I’m forced to touch the “Touch to Beam” UI. Isn’t it possible to have a bidirectional communication between two Android NFC enabled phones? I can even give up using NDEF if I can achieve the above behavior, mas I can’t accept that this limitation is real. In this way, it is not possible to write an application in a most used architecture where you need to perform an action based on a confirmation. The current onNdefPushComplete callback method will only tell my application that the message was correctly sent, but I have no way to know it was received by correct application and processed with success. Any help is appreciated. Best regards. Woody -- You received this message because you are subscribed to the Google Groups Android Developers group.

Are you using the openfire server or trying some how to connect driectly between two phones? If so, how are you publishing and discovering an IP? On Wed, Mar 28, 2012 at 4:46 AM, Woody Lemes N.

mdp, no no, I'm talking about NFC (Near Field Communication) in p2p mode, there is no IP involved in such techonology.

Oh yes sorry. I have not worked on NFC yet. Maybe some one that has will reply On Wed, Mar 28, 2012 at 9:44 AM, Woody Lemes N.
