To illustrate this functionality consider this scenario: Suppose you have a Twonky server at home (replace Twonky with your favorite Media Server) and you go visit a friend who has a brand new UPn P/DLNA device connected to his stereo and a Windows 10 PC with Window Media Player.Using your Android device and Bubble UPn P you can push music from your Twonky Server to his stereo.
This functionality can also be used on a regular LAN, for example to bypass regular UPn P SSDP device discovery in the rare cases it is not available for whatever reason (blocked by a firewall, UDP multicast disabled at the router level, ...).
Using Android Bubble UPn P or Bubble UPn P Tether client, you can make your Media Servers from your home local network visible on another LAN to any UPn P AV devices of this LAN (TV, Control Points, ...).
The information used to set this field is displayed in the Status tab of Bubble UPn P Server.
For example if the Status tab shows: To connect through HTTP, you must set "Server Address" to either or To connect through HTTPS, you must set "Server Address" to either https://1.2.3.051 or https://org:58051 Use the login that you defined in the Security tab.
Now every time your Android device switches to a mobile connection, Bubble UPn P will connect to Bubble UPn P server to make your Media Server available in the Devices tab.
And if you switch from a mobile connection to Wi Fi, it will disconnect and remove them from the Devices tab.With UPn P tethering you can do the same using the "Play to" functionality of Windows Media Player.In short, your Android device makes your home Twonky server visible to Windows Media Player on your friend's network. Many Media Servers have bugs and sometimes return incorrect data which can prevent them from working fully with some UPn P Software.For example you may want to connect to this network only when your Android device uses a Mobile data connection.In that case you would set this setting to "Mobile".Bubble UPn P Server can create a "proxy" Media Server (associated to a real Media Server on your LAN), that will attempt to convert incorrect data into correct data.
