所以几个月前我开始开发一些 WiFi-Direct 应用程序。几天前，我将我的 Galaxy Nexus 都更新为 Jelly Bean (4.1.x) 并测试了我的应用程序，但似乎又出现了问题。获得主要功能集已经很痛苦了在 ICS 上，但现在它不再工作了。
在我的 logcat 中，我得到的只是这样的：
/wpa_supplicant( 392): p2p0: P2P-PROV-DISC-PBC-REQ a2:0b:ba:xy:zz:xx p2p_dev_addr=a2:0b:ba:xy:zz:xx pri_dev_type=10-0050F204-x name='Android_e9f0' config_methods=0x188 dev_capab=0x27 group_capab=0x0

“邀请对话框”在第二部手机上正确弹出，并且“有时”（随机）它甚至可以工作，但仅在每五次尝试时才会出现。所以 logcat 告诉我，因为我不是 android-intern 代码的专业人士，所以协商根本就失败了，设备会丢失一小会儿，然后再次被发现，似乎有点混乱。
我的邀请是这样发出的：
public void onPeersAvailable(WifiP2pDeviceList peers) {
if (isInvitationSent)
return;
for (WifiP2pDevice dev : peers.getDeviceList()) {
WifiP2pConfig c = new WifiP2pConfig();
c.deviceAddress = dev.deviceAddress;
c.wps.setup = WpsInfo.PBC;
if (initiator
&& !isInvitationSent
&& WiFiSupport.compareMacAddressesInsensitive(MAC_ADDRESS,
dev.deviceAddress)) {
isInvitationSent = true;
sendInvitation(c);
}
}
}
private void sendInvitation(final WifiP2pConfig config) {
log("Sending invitation to " + config.deviceAddress);
mWifiManager.connect(mChannel, config, new ActionListener() {
@Override
public void onSuccess() {
log("Invitation sent!");
}
@Override
public void onFailure(int reason) {
log("Invitation failed!");
Toast.makeText(getApplicationContext(), "Could not connect to peer, reason:"+reason, Toast.LENGTH_LONG).show();
if (!retryChannel) {
log("Retrying to send invitation.");
retryChannel = true;
sendInvitation(config);
}
}
});
}
我在 android 上的 wifi direct 上阅读了很多内容，在我将手机更新为果冻豆之前它一直运行良好。任何人都知道，可能出了什么问题？如果您需要更多代码示例或代码的任何特定部分，请告诉我，因为我不知道什么是可靠的。
感谢您的帮助。

将 WifiP2pConfig.wps.setup 方法更改为“显示”，这导致设备 #1 显示 PIN 码，设备 #2 弹出一个带有输入字段的对话框 - 输入正确的 pin 后，这是 logcat 告诉我的：

有趣的是：08-31 15:13:43.491: W/wpa_supplicant(384): p2p-p2p0-3: 无法连接到内核驱动程序
我认为。对我来说，这看起来像是 Android 自己的 wifi-direct-framework 中的一个错误？
