Control devices over ethernet shield?
amjlopez 2012-04-10 03:39:43 5331 Views3 Replies I need to send UPD commands to a device connected to the ethernet shield. I am using UPDsendReceiveString code. But I don't find the way to include this parameters:
My device has IP 192.168.1.100 port (4352)
arduino IP 192.168.1.200
I want to send to the device this string "POWR 1" to switch ON/OFF
Can you help me please?
thank you very much

2012-04-11 18:47:09 Hi,
Actually at the end of the sample code there is a commented out section that explains how to do it.
Also, you could just define Udp.remoteIP, and Udp.remotePort manually.
[code]
// send a reply, to the IP address and port that sent us the packet we received
Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
Udp.write(ReplyBuffer);
Udp.endPacket();
}
delay(10);
}
/*
Processing sketch to run with this example
=====================================================
// Processing UDP example to send and receive string data from Arduino
// press any key to send the "Hello Arduino" message
import hypermedia.net.*;
UDP udp; // define the UDP object
void setup() {
udp = new UDP( this, 6000 ); // create a new datagram connection on port 6000
//udp.log( true ); // <-- printout the connection activity
udp.listen( true ); // and wait for incoming message
}
void draw()
{
}
void keyPressed() {
String ip = "192.168.1.177"; // the remote IP address
int port = 8888; // the destination port
udp.send("Hello World", ip, port ); // the message to send
}
void receive( byte[] data ) { // <-- default handler
//void receive( byte[] data, String ip, int port ) { // <-- extended handler
for(int i=0; i < data.length; i++)
print(char(data[i]));
println();
}

Hector 2012-04-11 01:09:07 Thank you very much for your response.
The code that I have was copied from Internet.
What I need is the following:
I have two Ethernet devices (Mitsubishi Projector).
Projector 1 has IP:192.168.1.10 port: 4352
Projector 2 has IP:192.168.1.11 port: 4352
Arduino IP: 192.168.1.12
I want to connect to an ethernet shield through a switch and send UDP commands to these devices.
Commands are very simple: "POWR 1" to switch ON and "POWR 0" to switch OFF. But I don't know how to send individually to each device.
Can you help me, please?
In the code that you sent me I don't how to wrtie the IP for the remote device.

I made a quick search on google and found: [size=78%][url=http://arduino.cc/en/Tutorial/UDPSendReceiveString]http://arduino.cc/en/Tutorial/UDPSendReceiveString[/url][/size]
Let me know if this helps. Otherwise I think I need a little more details about your problem. Could you post the sample code and tell me what you have tried? Hector
