Hello
I have and Wiznet IoShieldA that I connect to an Arduino DUE in order to become a TCP SERVER.
I downloaded Arduino IDE 1.6.12.
I copy in the Ethernet library the Wiznet Ethernet library.
in utility/w5100.h I uncommented #define WIZ550io_WITH_MACADDRESS
Then I wen to the the TCP Example
arduino.cc/en/Reference/EthernetServer
I copy this code in a new sketch, and I gives me an error.
Problem is in
if (client == true)Reading some forums, it seems the example is wrong and should modify it to
if (client)I changed the MAC (the one written in the Wiznet), IP and Subnet to be the one that fits my Server.
I donwloaded the code in my Arduino DUE+ioShield- A without trouble.
To test if it worked I connected ioshield by means of a crossed utp cable to the PC, I put the PC in the same net as Arduino, with the same mask.
I try to test the doe using AX1 application. I go to TCP> Connect … it takes some seconds, and finally Connection Failed message appears.
I don’t know why. Any help will be appreciated.
I tested the Arduino as Client using AX1 with the same configuration and it worked.
Here is my code:
[code]#include <Ethernet.h>
// network configuration. gateway and subnet are optional.
// the media access control (ethernet hardware) address for the shield:
byte mac = { 0x00, 0x08, 0xDC, 0x4D, 0xD1, 0x22 };
//the IP address for the shield:
byte ip = { 10, 1, 3, 1 };
// the router’s gateway address:
//byte gateway = { 10, 0, 0, 1 };
// the subnet:
byte subnet = { 255, 255, 255, 0 };
// telnet defaults to port 23
EthernetServer server = EthernetServer(3000);
void setup()
{
// initialize the ethernet device
Ethernet.begin(mac, ip);
// start listening for clients
server.begin();
}
void loop()
{
// if an incoming client connects, there will be bytes available to read:
EthernetClient client = server.available();
if (client) {
// read bytes from the incoming client and write them back
// to any clients connected to the server:
server.write(client.read());
}
}[/code]
