[SOLVED] Arduino ethernet shield 2 (W5500)

Hardware and Blynk Libraries

@naamah75 please share with us your sketch.

It is 100 req-sec

Iā€™m running the sample schetch:

  • to connect your project to Blynk.
  • Feel free to apply it to any other example. Itā€™s simple!
  • NOTE: You may have to install Arduino.ORG IDE to get it working:

  •   Pins 10, 11, 12 and 13 are reserved for Ethernet module.

  •   DON'T use them in your sketch directly!

#define BLYNK_PRINT Serial // Comment this out to disable prints and save space

Did you see sketch comments?

24

I was going to say I think you are missing your token.

Please paste the sketch again and then press the </> icon. I donā€™t need to see your token but I need to know it is not ā€œYourAuthTokenā€.

25

Yes I deleted the real token for privacyā€¦
Sorry for the </>

Iā€™ve examined my blynk.log on my serverā€¦
Every time I try to connect the app the server throw this exception:

Changed PIN, so now I not use 10,11,12 and 13, but the problem presist

28

Does your shield works without Blynk?

29

I just tested my W5500 with Arduino web server and web client sample sketches and seems to work very well.
I tested also my CC3000, this shield seem hang Arduino, but I would want to do more testing with this (even if the Arduino sample sketches seems to work).
Finally I try my ESP8266MODā€¦ Eureka! this works with both custom and cloud server! No errors at all.
Soā€¦ Now I have restricted the circleā€¦

  • my blynk server is OK.
  • my network and internet connection is OK.
    Maybe the blynk W5500 library could have some problem?
    Maybe my CC3000 shield could have a problem.
30

@naamah75 could you please try older Blynk library 0.3.1 for instance?

31

Okayā€¦ Iā€™m very confusedā€¦ I donā€™t know whyā€¦ but today the W5500 works very well, no one disconnection.
Never is changed on my sketch and on my hardware.
Iā€™ve just upgraded the app on my smartphone, but I think this isnā€™t related to my problem.
