I started working on android (ics) nfc applications. Now I have the scenario of using an nfc smartphone an another nfc device which should communicate with each other.
Not a real problem, but I need a kind of Request/Response scenario. Like the nfc smartphone is held in front to the nfc device and sends an key to it via nfc. The device takes the key and starts communicating with an backend system and after that sends a response back to the nfc smartphone. The smartphone gets the response, handles it, smartphone can’t be removed from device and we’re done.
But I really need the response. I did not get this done via the nfc possibilities android ics (beam) is offering.
So therefore my question. Is this somehow possible??
And if yes could somehow explain how? Like using an external library or creating an own?
I think probably you need the NFC to enable the phone’s Wifi-direct then do the two-way data transfer.
Or you may need to put the phone close to the device again, then do the beam again.
