How to use App Tethering with internet connection?

I'm using Embarcadero RAD Studio Delphi XE8.

Multi-Device Application app tethering components are designed for traditional WiFi and Bluetooth coupling. Does it support also Internet connections?

I would like to try to make small p2p app. I'm using App tethering via Wifi but I would like to connect App tethering via internet connection.

how to do that ?

Yes, TCP/IP (LAN and Internet) is also supported. This is clearly explained in the documentation.

Using App Tethering

The app tethering feature does not depend on a specific transport or protocol, and new transports and protocols can be implemented using the app tethering API. The RTL provides built-in support for IP and Classic Bluetooth connections. IP support includes connecting applications running on the same device.

IP connections are not limited to WiFi only. WiFi is just a wireless connection to a LAN, much like Ethernet is for wired connections. IP works the same regardless of the type of connection used.

Connecting to Remote Applications Using App Tethering | Connecting to Applications Outside Your Subnet

By default, both AutoConnect and DiscoverManagers perform the discovery on the subnet of the local area network (LAN) where the device running your application is.

However, you can use their optional parameter Target to override this behavior, and specify an IP address or subnet:

  • To specify an IP address to search for remote managers, specify that IP address as the Target.

  • To specify a subnet of IP addresses, specify an IP address with a 0 as its fourth number. For example, if you specify "192.168.4.0" as the Target, your manager searches the 192.168.4.x subnet for remote managers. Note: You can not specify wider subnets. For example, "192.168.0.0" is not supported.
