Hi, i'm new in arduino's WORLD. I create a web switch with a enc28j60 but i don't know the reason when i try to control the board over the internet, it doesn't work. I only see the ''web page'' and can't control  any led from the 3 i set. In lan it works perfectly !


i open the port 85
check this sketch :
Code: [Select]
#include "etherShield.h"


// please modify the following two lines. mac and ip have to be unique
// in your local area network. You can not have the same numbers in
// two devices:
static uint8_t mymac[6] = {0x54,0x55,0x58,0x10,0x00,0x24};
static uint8_t myip[4] = {192,168,1,15};
static char baseurl[]="http://192.168.1.15/";
static uint16_t mywwwport =85; // listen port for tcp/www (max range 1-254)



#define BUFFER_SIZE 1500
static uint8_t buf[BUFFER_SIZE+1];
#define STR_BUFFER_SIZE 200
static char strbuf[STR_BUFFER_SIZE+1];

EtherShield es=EtherShield();

// prepare the webpage by writing the data to the tcp send buffer
uint16_t print_webpage(uint8_t *buf, byte on_off1, byte on_off2, byte on_off3);
int8_t analyse_cmd(char *str);

// LED cathode connects the Pin4, anode to 5V through 1K resistor
#define LED_PIN4  4
#define LED_PIN5  5
#define LED_PIN6  6
    uint16_t plen, dat_p;
  int8_t cmd;
  byte on_off1 = 0;
  byte on_off2 = 0;
  byte on_off3 = 0;

void setup(){

   /*initialize enc28j60*/
es.ES_enc28j60Init(mymac);
   es.ES_enc28j60clkout(2); // change clkout from 6.25MHz to 12.5MHz
   delay(10);
       
/* Magjack leds configuration, see enc28j60 datasheet, page 11 */
// LEDA=greed LEDB=yellow
//
// 0x880 is PHLCON LEDB=on, LEDA=on
// enc28j60PhyWrite(PHLCON,0b0000 1000 1000 00 00);
es.ES_enc28j60PhyWrite(PHLCON,0x880);
delay(500);
//
// 0x990 is PHLCON LEDB=off, LEDA=off
// enc28j60PhyWrite(PHLCON,0b0000 1001 1001 00 00);

//

// enc28j60PhyWrite(PHLCON,0b0000 1001 1001 00 00);
es.ES_enc28j60PhyWrite(PHLCON,0x990);
delay(500);
//
  // 0x476 is PHLCON LEDA=links status, LEDB=receive/transmit
  // enc28j60PhyWrite(PHLCON,0b0000 0100 0111 01 10);

delay(100);
       
  //init the ethernet/ip layer:
  es.ES_init_ip_arp_udp_tcp(mymac,myip,85);
 



Thx in advance

SRY In lan, when i open the port 85 it doesn't work. When I set default seting (port and ip) it works

Did you assign a static IP and open the ports both through you wireless router and your ISP router? I forgot the ISP once, drove me insane.

Hanrun

there is no isp router but Modem. And yeah in my router the port is open. As i said, i can see the web page over the internet, but i can't do any action.



Nick Gammon

You haven't exactly posted the whole sketch, so it's all guesswork really. But I doubt this is right:

Code: [Select]
static char baseurl[]="http://192.168.1.15/";

If you are generating forms, and that form is designed to respond to baseurl, then it will go back to the wrong address.

Also, what Arduino board are you using?
Please post technical questions on the forum, not by personal message. Thanks!

I use ENC28J60 the cheapest version of a real ethernet shield w5100 haha!


I try 192.168.1.15:85 but it do not work

The sketch I posted is only the ''ethernet'' part, the rest is to control ledpins. If you realy want i can show all my sketch.

Nick Gammon

Which Arduino are you using? Uno? Mega2560?

Yes, show the whole sketch.

192.168.1.15 is not an address that is routable on the internet. Your router/firewall will have a different IP address when seen from the outside internet. Thus, any form that references that address simply won't work from the outside.
Luckily, HTTP already defaults the base URL to whatever you used to get to the form in the first place. Thus, you can try changing the baseurl to simply "/" and it might have some chance of working, if I read that sketch right.
That is -- assuming you can get to the page in the first place, then posting the form should work if you set the baseurl to "/" rather than a specific protocol and address.

with this change, i can control trough the lan, not over internet.

I creat a DNS with my dhcp IP   ex:

71.112.345.3 is now Mydomain.no-ip.com
I opened the port 85 both udp & tcp
I can acces my router from anywhere with : Mydomain.no-ip.com
but nothing work with  http://mydomain.no-ip.com:85/

In "code" tags, not "quote" tags thanks. It makes it (almost) impossible to read. Edit those posts and change [ quote ] to [ code ] (leaving out the spaces).
