下面就是我想要做的2银河Nexuses运行Android 4.0 NFC功能：

Here's what I'm trying to do with 2 Galaxy Nexuses running Android 4.0 with NFC capabilities:

我有一个从最初的梁 - >乙工作正常，但不能通信回来。我也想送更多的东西不仅仅是一个ACK，就像一个小的有效载荷数据。有没有办法做到这一点在NFC与当前的API或我将不得不把目光投向WIFI / BT等P2P通信？

I have the initial beam from A -> B working fine but not the communication back. I do want to send something more than just an 'ACk', like a small payload of data. Is there any way to do this over NFC with the current APIs or will I have to look towards WiFi/BT p2p communication?

推荐答案

我不认为这是可能的，除非你拉设备分开，然后从Device B把它们放在一起一次明确束数据到与触摸梁UI。您可以使用NFC来，虽然启动BT连接，并把工作做好。

I don't think this is possible unless you pull the devices apart then put them together again and explicitly beam data from Device B to A with the touch to beam UI. You can use NFC to initiate a BT connection though and get the job done.
