Send Value from Blynk app

Solved
1

Hello everyone;

I need some help please with my project.

I am sending the delay (xxx) value to my ESP8266 from Blynk app from mobile.

delay (xxx) ;

It works perfectly and I can change the delay as I wish. The problem that every time I reset the ESP8266, I must reconnect the app to the board again and set the delay. Is there any way to save the last xxx value I send even after resetting?

Thank you.

And you shouldn’t be using delays in your Blynk sketch, they block the code operation and can lead to Blynk disconnections and will certainly result in non-responsiveness of the hardware to widget changes in the app.
You should look at lambda timeout timers instead.

Thank you for your replay.

No problem as I need to use Blynk once when starting the project to set some variable without needing to edit the code every time. it works perfectly now.
