UDP Socket programming

Hello,

we´re testing the IoT2020 for a school project. We want to use a UDP Socket to connect to a PC. Is there any Guideline for a simple test Sketch and which libraries I have to include?

We use the Eclipse IDE to write our code.

Thanks for your help!

Hi,

If you are going through C/C++ use the standard.

Usual Includes:

#include <sys/socket.h>  // Core BSD socket functions and data structures.
#include <netinet/in.h>    // AF_INET and AF_INET6 address families and their corresponding protocol families PF_INET and PF_INET6.
#include <arpa/inet.h>    // Functions for manipulating numeric IP addresses.
#include <netdb.h>         // Name resolution

Best Regards!
