[ESP8266/D1Mini] HeartBeat Timeout

Issues and Errors
1

Hey together,

after finishing my project, i´ve tested the code and my ESP for one day.

After 1-2 minutes, the console send me the error “HeartBeat Timeout”…
Then it tries to reconnect constantly, but doesn´t work…
Can someone give me some tips or tell me what it is?

Thank u!

There is something quite strange happening in your code which i cannot understand why you have done it

timerNr2 = timer.setInterval(200000, startFeuchte);
timer.disable(timerNr2);
//Thats OK//

void startFeuchte()
{
  feuchteSenden(); //??????
}

void feuchteSenden(){
  Serial.println("Feuchte: ");
  Serial.print(feuchte);
  Serial.print("%");
  Blynk.virtualWrite(V4, feuchte);
}

Why have put put a function within a function??
You could just do

timerNr2 = timer.setInterval(200000, feuchteSenden);
timer.disable(timerNr2);

void feuchteSenden(){
  Serial.println("Feuchte: ");
  Serial.print(feuchte);
  Serial.print("%");
  Blynk.virtualWrite(V4, feuchte);
}
//And delete void startFeuchte() altogether.

Hey

Yeah I know. But if I don’t do this, it don’t accept my code.
If I put the function in a function it works.
Idk why :man_shrugging:

What widget is V10?

V10 is Menu switch with Automatic and Manual option

What does that mean exactly?

Weird.
When I first programmed it that way, IDE did not want to accept it.
Now I made it like that again, now it works.

But still the same problem…

8

And, there is a problem with this code…

  for (i = 0; i < 10; i++)  //
  {
    feuchte += analogRead(A0); 
    delay(20);   
  }
  feuchte = feuchte / (i);

10 readings will be taken (i=0 through to i=9) but the result will be divided by 9, not 10.

What is this?

@PeteKnight
So I have to start with
for (i=1; i<10; i++)?
Or
feuchte = feuchte / 10

@proietti
Includes the Blynk library.

Either solution would work.

It’s not necessary.

Thank you again Pete.

Tomorrow I’ll change my D1mini and try it again.
Maybe it’s a hardware issue, because till yesterday it works fine and today it stuck…

I’ll give you tomorrow response, thanks for helping me.
