UE-UDP: or named UEUDP, Unreal Engine UDP. 

This plugin encapsulates the implementation of UDP. Only need to use the blueprints, you can send and receive UDP messages. This plugin supports multiple platforms: iOS, Windows, Mac, etc. It supports Unicode(UTF8) characters. After using this plugin, you will find that it is so simple to receive and send UDP messages. In addition, this plugin also provides additional Wake-on-LAN functionality.

NOTES: Solutions for "The String ends with garbled characters."

To prevent garbled characters at the end of the String (such as the "NewUDPMessageString" parameter of "OnReceivedNewUDPMessageMulticastDelegate"), Bytes sent via UDP must end with the '\0' character.

Solution 1: Send the Bytes with '\0' (uint8 value is 0) at the end.

Solution 2: Add '\0' (uint8 value is 0) to the end of received Bytes. Then use the "Convert bytes to string" function to convert Bytes to String.
