适用于多种设备的WiFi Direct [英] WiFi Direct for multiple devices

问题描述

我正在尝试通过

http://developer.android.com/training/connect-devices-wirelessly/wifi-direct.html

这已说明了如何管理2台设备之间的连接.经过关于stackoverflow的一些帖子后，此帖子- WiFi Direct(Android 4.0)和多个(3个以上)设备解释了如何以A-> B和C-> B的方式连接3台设备，我将B视为组所有者.我想知道是否可以通过某种方式同时传输B-> A和B-> C的文件.

This has explained how to manage connections between 2 devices. After going through some posts on stackoverflow, this post - WiFi Direct (Android 4.0) with multiple (3+) devices has explained how to connect 3 devices in a manner where A->B and C->B, where I've considered B as my Group Owner. I wanted to know if there is any way in which I can transfer a file in a manner where B->A and B->C simultaneously.

感谢您的所有帮助！:)

Thanks for all your help! :)

推荐答案

由于B是组所有者(GO)，A和C是客户，因此B可以通过 WifiP2pManager.requestGroupInfo的回调函数获取客户的地址.().

Since B is the group owner(GO) and A and C are clients, B can get clients' address by the callback function of WifiP2pManager.requestGroupInfo() .

像这样连接后请求群组信息.

Request group info after connected like this.

mWifiP2pManager.requestGroupInfo(mChannel,new WifiP2pManager.GroupInfoListener() {
        @Override
        public void onGroupInfoAvailable(WifiP2pGroup wifiP2pGroup) {
            Collection<WifiP2pDevice> peerList = wifiP2pGroup.getClientList();
            ArrayList<WifiP2pDevice> list = new ArrayList<WifiP2pDevice>(peerList);
            String host;
            for (int i = 1; i < list.size(); i++) {
                host = list.get(i).deviceAddress;
                /** transferFile here **/
            }
        }
    });
