Are you using Blynk IoT or Blynk Legacy?

What version of the ESP32 arduous using?

Pete.

4

I am using Blynk IOT
And it’s ESP8266

5

you’ve

You should be using Blynk library version 1.2.0 and I’d recommend opening the latest version of the example you are using, once you’ve installed that version I’d recommend opening one of the examples that are installed with that library.

What version of the ESP8266 Core do you have installed?

Pete.

6

It’s 3.1.2

7

It worked with the library update of the Blynk
