Hi all..
I have a big problem. I used pic18f67j50 and enc28j60. I created new project with ccs wizard. I used http client project. I tried below option.
1- auto ip (dhcp enable) connect to www.mypage.com result is OK
2- auto ip (dhcp enable) connect to 216.70.123.120 (example ip) result OK
3- static ip (dhcp disable) connect to 216.70.123.120 (example ip) result OK
4- static ip (dhcp disable) connect to www.mypage.com result is FAIL
what is the problem?
Thanks |

well I tried going to www.mypage.com.. and my W7 FFox says insecure connection, and it'll track my PC. Also nothing comes up(I assume that's my browser protecting me...)
I'll assume the PC with www.mypage.com is running from needs to be configured to allow the PIC (and me..) to connect. |

How is it going to find the IP address of www.mypage.com?.
Remember DHCP supplies the DNS address as well.
I'd suspect it can't resolve the name to an IP address. |

| I thing i solved problem. If I wait 30 sec. it has not problem. Because HttpClientIsBusy() function returned value 0. 30 sec. later returned value 1 and i can send data. |

if(DNSBeginUsage()) DNSResolveROM("mcugomsis.site",DNS_TYPE_A);
DNSEndUsage();
printf(lcd_putc,"%03u:%03u:%03u:%03u",ResolvedInfo.IPAddr.v[0],ResolvedInfo.IPAddr.v[1],ResolvedInfo.IPAddr.v[2],ResolvedInfo.IPAddr.v[3]);
returned 000.000.000.000
I don't understand how is it resolve dns |

You do understand, that a device wanting to connect to a 'named' location on the internet, has to issue a DNS request to get this resolved to a physical IP address.
To do this is has to know the IP address of the DNS server the network is allowed to use (so either a specific IP for your service provider or a 'public' one like Google). With this it can 'call' this address and ask for the IP address corresponding to the name. Without knowledge of where to go for DNS, the device can't resolve a name to an IP address.
Now your device was being given the IP of the DNS server by DHCP. You have disabled DHCP, so it doesn't know who to ask for the IP address. With DHCP disabled, the code on your device will need to have a legitimate DNS server address 'hard coded'.
I have to ask 'why'?. Just use DHCP. That is what it is there for.... |

| So setup a static IP on the firewall for the device. You can still use DHCP. |

| So just second. You say to me you use DHCP and you can use static ip for device. Is true? If yes how? |

Your firewall should have an option to supply a fixed address to specific devices. Static DHCP.
<https://wiki.dd-wrt.com/wiki/index.php/Static_DHCP>
This is an example for a particular router. However most/all offer this.
This is how you can do things like port forwarding for a data server sitting on a network.
Your device then behaves as a normal device on the network, but when the router 'sees' it's particular MAC address in a DHCP request, it will always give it the same IP. |

Thanks for your answers. I think first choice is the best for me.

1- i sent to thingspeak my ip address.
2- i want to data like below command (pic or browser)
| Code: | | http://18.235.222.172/channels/600214/fields/1.json?api_key=.....api_key...&results=2 |
3- thingspeak's answer
| Code: | | {"channel":{"id":600214,"name":"IP","latitude":"0.0","longitude":"0.0","field1":"Field Label 1","created_at":"2018-10-11T19:21:47Z","updated_at":"2018-10-11T19:21:47Z","last_entry_id":1},"feeds":[{"created_at":"2018-10-11T19:31:04Z","entry_id":1,"field1":"035.233.222.163"}]} |
This is my ip : field1":"035.233.222.163"
After that i used static ip and i sent to server successfully. Because i use ip number (server ip number).
If change my ip later, i can change on the thingspeak.
Maybe my method is stupid, but it works. |
