You can easily use TCP and UDP connections to send and receive data in blueprints with this plugin . This is a client. You can find my server plugin here. You don't need C++. I recommend my JSON plugin for data communication. I recommend this tool for testing and developing. Nativizing may not be possible in the blueprints where the plugin is used.

A demo for searching for LAN servers is also available in the documentation. Screenshots, Video

Version 2.00 tested on: Windows 10, Android 7.1.2 (S4 mini with LineageOS). IOS 12.1.2 (iPhone 5s).
