Jan 16, 2017 · In UDP there are no connections, just senders and receivers. In your set up, if the arduino is "streaming" (i.e. sending) data, it is the UDP sender and it must know the IP address (and listening port) of your the receiver (your PC). It simply opens a socket and uses socket.sendto (or the equivalent of the Arduino API) to send UDP packet to. Sending UDP Packets across the Internet with Python sockets module. For a class, I have to develop a socket listener for a Windows machine in C# and a packet sender in Python. Everything works fine when I send the packets on the localhost. The Python UDP packets are sent and the C# socket receives and reads the packets just fine. Udp Server Code. The C++ example also shows a simple implementation of sending several packets of telemetry similar to the Python example above. Each payload contains data of all message types.
