The code I’m pasting uses the OSC library, but I get the same results without OSC, using UDP.write. And it will also receive the button status from Circuit-2. It will transmit the information in form of UDP packets.

Occasionally it will speed up to ~5ms for a second or two, then drop back to 400ms. It will transmit various data like temperature reading, Flame detection Status, and Push Button Status (On/Off) to the Circuit-2 using UDP Protocol through Ethernet cable. Sending to a single address works great, I see about 0 - 2ms between received messages (which I’m assuming is network latency).Ĭalling UDP.beginPacket/endPacket twice in the loop, however, gives me ~400ms between received messages. Once a packet is received, the code will printing out the IP address and port of the sender as well as the length of received packet. I seem to be sending exactly what I think I am. When I send this packet, I can confirm it through Wireshark on my PC. Drop UdpBytewise.h/. and I've updated the Arduino code to reflect that. UdpBytewise.cpp: Library to send/receive UDP packets with the Arduino ethernet shield. It also has a built-in HTTP client for GET/POST requests and Panel Generation for the creation of complex control systems. Features Packet Sender can send and receive UDP, TCP, and SSL on the ports of your choosing.

EthernetServer server(80) The int variable ‘led’ stores the Arduino digital pin connected with the anode pin of the LED. This will be the port where the server will listen to the requests.

I’m trying to send UDP packets to multiple IP addresses from a single Arduino Uno with an Ethernet shield. / include
