Hi I am absolute newbee using ENC28J60, I want to upload some data to my seerver (in php) :
I take a php hosting from 0fees and now I can send the data to my server using : http://ashutest123.0fees.us/dataupload1.php?data=somedata and check the uploaded list of data in the table as http://ashutest123.0fees.us/showdata.php ——— u can take a view yourself.
I wrote an arduino code (using Aruino Uno and ENC28J60 module from ebay.in) using UIPEthernet lib
#include <UIPEthernet.h> // Used for Ethernet
// **** ETHERNET SETTING ****
// Arduino Uno pins: 10 = CS, 11 = MOSI, 12 = MISO, 13 = SCK
// Ethernet MAC address - must be unique on your network - MAC Reads T4A001 in hex (unique in your network)
byte mac[] = { 0x54, 0x34, 0x41, 0x30, 0x30, 0x31 };
// For the rest we use DHCP (IP address and such)
EthernetClient client;
char server[] = "ashutest123.0fees.us"; // IP Adres (or name) of server to dump data to
int interval = 5000; // Wait between dumps
void setup() {
Serial.begin(9600);
Ethernet.begin(mac);
Serial.println("Tweaking4All.com - Temperature Drone - v2.0");
Serial.println("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\n");
Serial.print("IP Address : ");
Serial.println(Ethernet.localIP());
Serial.print("Subnet Mask : ");
Serial.println(Ethernet.subnetMask());
Serial.print("Default Gateway IP: ");
Serial.println(Ethernet.gatewayIP());
Serial.print("DNS Server IP : ");
Serial.println(Ethernet.dnsServerIP());
}
void loop() {
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("-> Connected");
// Make a HTTP request:
client.print( "GET /dataupload1.php?");
client.print("data=");
client.print( "somedata" );
client.println( " HTTP/1.1");
client.print( "Host: " );
client.println(server)
client.println( "Connection: close" );
client.println();
client.println();
client.stop();
}
else {
// you didn't get a connection to the server:
Serial.println("--> connection failed/n");
}
delay(interval);
}
when I run it in serial monitor it shows all ip, dns, gateway etc addresses as 0.0.0.0 ---- seems no dhcp abtained then shows "connected"
no data goes to my server
Please help me I am in a need of it
Thanks in advance
You might want to try this example code, it might help you alot to understand your problem and where it come from.
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {
0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02
};
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
// this check is only needed on the Leonardo:
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
for (;;)
;
}
// print your local IP address:
printIPAddress();
}
void loop() {
switch (Ethernet.maintain())
{
case 1:
//renewed fail
Serial.println("Error: renewed fail");
break;
case 2:
//renewed success
Serial.println("Renewed success");
//print your local IP address:
printIPAddress();
break;
case 3:
//rebind fail
Serial.println("Error: rebind fail");
break;
case 4:
//rebind success
Serial.println("Rebind success");
//print your local IP address:
printIPAddress();
break;
default:
//nothing happened
break;
}
}
void printIPAddress()
{
Serial.print("My IP address: ");
for (byte thisByte = 0; thisByte < 4; thisByte++) {
// print the value of each byte of the IP address:
Serial.print(Ethernet.localIP()[thisByte], DEC);
Serial.print(".");
}
Serial.println();
}
Then I let you edit your code with your custom functions to get all informations you might need.
Note that if you set an hard-coded IP address even in a DHCP range it will be working.
