Ditto is a technology enabling devices to connect and sync data without the internet by utilizing available network transports to form a mesh network. This capability is demonstrated through the Ditto Presence Viewer, which visually displays how devices recognize and connect with nearby peers using LAN, WiFi-direct, and Bluetooth low energy. In a practical demonstration, two iOS devices and one Android device running Ditto illustrate the seamless connection management, with iOS devices maintaining a stable link via Apple Wireless Direct Link (AWDL) while WiFi and Bluetooth connections are dynamically enabled and disabled to show Ditto's ability to disconnect and reconnect. Although multiple transport connections can be established between two peers, Ditto ensures efficiency by keeping only one virtual connection active. Further insights into Ditto's network transport handling are available through their blog post on the multiplexer, and interested users can test the Presence Viewer by downloading the demo apps for iOS and Android.
