Android的NFC：SNEP协议和P2P响应 [英] Android NFC : SNEP protocol and P2P response
问题描述
我想实现两个Android手机（其中一人将通过一个独立的设备最终被替换）之间的P2P通信。我已经看到了安卓4.0支持SNEP这是由NFC论坛公布，并应可在非Android设备。
I am trying to implement a P2P communication between two Android phones (one of them will be replaced by an independent device in the end). I have seen that Android 4 supports SNEP which is published by the NFC forum and should be available on non-android devices.
我有以下的谷歌教程NFC P2P（http://developer.android.com/guide/topics/nfc/nfc.html#p2p），我可以从一个手机发送一些信息给对方，但我有几个问题：
I have following the Google tutorial for NFC P2P (http://developer.android.com/guide/topics/nfc/nfc.html#p2p) and I can send some information from one phone to the other, but I have a few questions:
- 在Android的光束仅仅是一个名称，NFC，或者是一款Android协议工作在SNEP / NPP？如果它是一个协议，该怎么办NFC点对点无梁？
- 如何设置使用SNEP的？
- 如何发送到其他设备的响应，当连接被初始化（接收第一消息）？
感谢您的帮助！
推荐答案
Android的光束只是一个名字，正确的。设备使用SNEP默认情况下，如果失败，它会尝试核电站。不能从接收装置向发送方发送响应真。一个成功的推只能使用一个回调来通知：
Android Beam is just a name, correct. Devices use SNEP by default, if that fails, it tries NPP. You can't send a response really from the receiving device to the sender. You can only use a callback to be notified of a successful push:
