本文介绍了TDLS（Tunneled Direct Link Setup）无线标准，该标准允许设备通过WiFi网络进行点对点直连，节省带宽并提高连接质量。文章详细解释了如何通过设置特定IP地址或MAC地址启用或禁用TDLS，并提供了与之相关的API介绍。

一，WifiManager

　　新增：

 1 public void setTdlsEnabled (InetAddress remoteIPAddress, boolean enable)
 2     
 3 Enable/Disable TDLS on a specific local route.
 4 
 5 TDLS enables two wireless endpoints to talk to each other directly without going through the access point that is managing the local network. It saves bandwidth and improves quality of the link.
 6 
 7 This API enables/disables the option of using TDLS. If enabled, the underlying hardware is free to use TDLS or a hop through the access point. If disabled, existing TDLS session is torn down and hardware is restricted to use access point for transferring wireless packets. Default value for all routes is 'disabled', meaning restricted to use access point for transferring packets.
 8 
 9 Parameters
10 remoteIPAddress    IP address of the endpoint to setup TDLS with
11 enable    true = setup and false = tear down TDLS

public void setTdlsEnabledWithMacAddress (String remoteMacAddress, boolean enable)

Similar to setTdlsEnabled(InetAddress, boolean), except this version allows you to specify remote endpoint with a MAC address.

Parameters
remoteMacAddress    MAC address of the remote endpoint such as 00:00:0c:9f:f2:ab
enable    true = setup and false = tear down TDLS

　　变更：

public DhcpInfo getDhcpInfo ()

Return the DHCP-assigned addresses from the last successful DHCP request, if any.

Returns
the DHCP information
