Help me with not updating button state

[Blynk_Coeur]

Haha

I have to write your code and test it

can you try to change V2 push mode to switch mode in the phone App ?

[waleedtaqi7]

i did try both, currently its in switch mode. No luck!

[Blynk_Coeur]

Ok I’m writing your code to see where is the bug

[Blynk_Coeur]

That works for me :

void checkPhysicalButton()
{
  if (digitalRead(P1) == LOW) {
    // btnState is used to avoid sequential toggles
    if (btnState != LOW) {

      // Toggle LED state
      ledState = !ledState;
      digitalWrite(ledPin, ledState);

      // Update Button Widget
      if(ledState==0){
      Blynk.virtualWrite(V2 , LOW);
      }else{
       Blynk.virtualWrite(V2 , HIGH);
      }
    }
    btnState = LOW;
  } else {
    btnState = HIGH;
 // Update Button Widget
     
  }
}

okay flashing it, and i want to show you this.
in phone app it works on GPIO ( digital ) GP0,
Not virtual.

[waleedtaqi7]

getting this error now…

error: ‘P1’ was not declared in this scope; did you mean ‘y1’?
98 | if (digitalRead(P1) == LOW) {
| ^~
| y1
exit status 1
‘P1’ was not declared in this scope; did you mean ‘y1’?

[Blynk_Coeur]

Yes replace P1 by btnPin
But V2 can’t work because you have select digitalPin instead of virtualPin

[waleedtaqi7]

Thats why im telling you…it is working on digitalpin…nothing works if i select V2

@waleedtaqi7

i got it working before somehow but i don’t remember.

Maybe you should look at your previous post…

Need help with this code (run the code if there is no internet or wifi)

i am making a project of standalone ESP8266 with single channel relay with a synced physical button. the code works fine. i just want to run the code if there is no internet or wifi is off. The code does not run without Internet. here is my code #define BLYNK_PRINT Serial #include <ESP8266WiFi.h> #include <BlynkSimpleEsp8266.h> // You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "88decc9cb88340c9a5bead06423469d3"; // Your WiFi credentials. …

Pete.

[waleedtaqi7]

yeah i have seen it but it was posted before fixing the button sync issue.

[Blynk_Coeur]

You can’t control V2 if it isn’t a virtual button

[waleedtaqi7]

Still no luck its not working…
we need to look somewhere else… look at the url it is working with D0 “”“oT5y/update/D0?value=0"”" not with V2.

God!!!

[PeteKnight]

Maybe the Sketch Builder “Sync Physical button” example is where you should start,

Pete.

@ [Blynk_Coeur]

Man it started to pick on V2 but the problem is " button states changes for a mili sec and goes back to off

[Blynk_Coeur]

@waleedtaqi7

// When App button is pushed - switch the state
BLYNK_WRITE(V2) {
  ledState = param.asInt();
  digitalWrite(ledPin, ledState);
}

The problem is here …
I think you have to start from scratch

[waleedtaqi7]

EEEEEEHAAA!!! WE SOLVED IT MAN

i removed the line

Blynk.virtualWrite(V2, millis() / 1000); // Send UpTime seconds to App

Its working now…tell me how do i buy you a coffee ?

[Blynk_Coeur]

[waleedtaqi7]

why shhhhh ?
let others taste the fruit of our tree.

[Blynk_Coeur]

Ok I just saw that

Blynk.virtualWrite(V2, millis() / 1000);  // Send UpTime seconds to App

[waleedtaqi7]

Comon DM me, i really need to say thanks to you.
Because you made my smart farmhouse project completed because i need lots of these.
