Wi-Fi直接连接问题

我正在尝试使用Android自己的Wi-Fi直接接口将设备直接与另一台设备配对。

但是我在接受来自类似设备的传入群组邀请时遇到问题。

从客户端我设法得到这个错误:

GO(组所有者)使用以下代码连接:

WifiP2pConfig config = new WifiP2pConfig();
                    config.deviceAddress = device.deviceAddress;
                    config.groupOwnerIntent = 15;
                    config.wps.setup = WpsInfo.PBC;

                mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() {

                    @Override
                    public void onSuccess() {

                        new FetchDeviceInfo().execute(device);

                    }

                    @Override
                    public void onFailure(int reason) {
                        // TODO Auto-generated method stub
                        Toast.makeText(getBaseContext(), "Failure to connect: " + reason, Toast.LENGTH_SHORT).show();


                    }
                });

执行Asynctask只是为了获取客户端IP地址。

如果两个设备都想成为组所有者(config.groupOwnerIntent == 15),则协商组所有者的协议将失败。如果GO意图相同并且会成功,那么任何下面都有一个决胜局位。

我连接两台设备(使用您的代码)的方式如下:

WifiP2pConfig config = new WifiP2pConfig();
    config.deviceAddress = device.deviceAddress;
    config.wps.setup = WpsInfo.PBC;
    Random r = new Random();
    config.groupOwnerIntent = r.nextInt(14);

    mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() {
    ...
