Can't connect except for telnet

@bernas_123 so seems USB works for you, right? Are you able to make blinking some LED?

bernas_123 · October 25, 2015, 6:08pm

sucess! it works, making the led blink! thank you very much!
what about now with the ethernet shield?

Dmytro · October 25, 2015, 6:33pm

Well, it was just a start =). Now we know that you have no router issues, no library issues and no arduino issues. So it’s time for Ethernet shield. Please plug Ethernet shield and try again basic Ethernet example. Try to connect without changing anything (just put auth token). Do you see again

[0] Blynk v0.3.1
[0] Getting IP...

? and nothing happens for a long time?

bernas_123 · October 25, 2015, 6:37pm

yes i stilll get the same thing…

Dmytro · October 25, 2015, 6:45pm

No more output? How long did you wait?

bernas_123 · October 25, 2015, 6:47pm

yes i get “getting ip”, i waited for 10 min ±, should i wait more? i once left it for an hour and it doesn’t connect

Dmytro · October 25, 2015, 7:04pm

No =). Your code below should work

byte arduino_mac = { 0x90, 0xA2, 0xDA, 0x10, 0x1F, 0xC4 };
IPAddress arduino_ip ( 192, 168, 1, 70);
IPAddress dns_ip ( 8, 8, 8, 8);
IPAddress gateway_ip ( 192, 168, 1, 254);
IPAddress subnet_mask(255, 255, 255, 0);

Just wait a bit. You could see few

Connecting to cloud.blynk.cc:8442

Until you really be connected.

Dmytro · October 25, 2015, 7:05pm

By the way. Where this from

[1300] My IP: 0.106.106.106

?

bernas_123 · October 25, 2015, 7:07pm

i was just replying that, i don’t know i keep getting that even with your code:

Here is some problem with your IP. Try to change from

192,   168,   1,  70

to another. Maybe this one is busy.

bernas_123 · October 25, 2015, 7:13pm

tried already several and im tryinng others too, i receive that message always

Dmytro · October 25, 2015, 7:14pm

Try

IPAddress arduino_ip ( 192,   168,   1,  62);

this one is out of DHCP pool.

bernas_123 · October 25, 2015, 7:16pm

yeah the same thing… what a mystery

Dmytro · October 25, 2015, 7:19pm

Did you restart your router already? Sometimes it helps. I’m out of ideas. The thing is - your router doesn’t give Arduino correct IP.

bernas_123 · October 25, 2015, 7:22pm

yeah restarted and reseted… maybe i should abandone the ethernet shield and go for a wifi shiel or would i have the same problem?

bernas_123 · October 25, 2015, 7:25pm

but its strange cause i have the official ethernet shield rev2, i can connect form my laptop to the cloud and never had a problem connecting devices to my network, never used ethernet tough except for my tv recorder that my provider set up for me but it works great…

one last time this is the code that im using, i think everything is ok…:

@vshymanskyy any ideas?

bernas_123 · October 25, 2015, 7:39pm

This is my physical connection, the grey one without the protection is connected to arduino

djinn111 · October 25, 2015, 8:34pm

hello there.
I started with the ethernet shield and blynk . i have been facing the same issue and had been struggling with it for the last 100hrs. After some RnD, i stumbled upon your post and found that i am having the exact issue just like yours.

the last sketch as u tried, my serail monitor showing this
