Before creating the topic

  1. Search forum for similar topics
  2. Check and
  3. Add details :
    • Hardware model + communication type. For example: Arduino UNO with Ethernet Shield
    • Smartphone OS (iOS or Android) + version
    • Blynk server or local server
    • Blynk Library version
    • Add your sketch code. :point_up:Code should be formatted as example below.

Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.

void loop()

Does the app work from your phone?
Can you login, create a blank project?

yes, i have account in the app
and create my project with arduino uno & ethernet shield but it always offline

Blynk-cloud is probably working just fine than.

I’d repost this question as “Trouble connecting with Arduino w/ Eth sheild”

Post the sketch you are using. Maybe add the comment you are in syria.

I don`t know how to post the sketch and i tried.
anyway we are connecting to the internet by ‘‘ADSL’’
and my speed is 2mbit … is this enough

How does your code compare to the example code?

my code is just like that from examples
i’ve added my auth token; it was send to mail
I am not a programming expert but I have instructions from YouTube

There are dozens and dozens of threads on the forum about getting your hardware combination to work. Problems are mostly around using too high a baud rate with SoftwareSerial, not having your ESP-01 set to use the correct (same) baud rate, not crossing the Rx and Tx connections between the Arduino and ESP-01 or not having a suitable separate power supply for the ESP-01.

Do some searching and some experimentation and you’ll come up with an answer.
