[SOLVED] Toggling between two commands

Need Help With My Project
1

Dear Sirs,
I am trying to implement something and I have stucked at a very silly point.
What i want? Using a virtual pin as switch in push mode, I want the first time that I push the Blynk virtual button (switch) my ESP application to execute command 1, the second time to execute command 2… in short to toggle between command 1 and command 2…
How??? I burned my head to solve this simple problem…

Thanks and Best Regards,
Mike Kranidis

The shorthand for “toggling” is something like:

yourvariable = !yourvariable;

Longhand:

if (yourvariable == 1){
  yourvariable = 0;
  //do something
}
else{
  yourvariable = 1;
  // do something different
}

Hello @Costas!

I am using BLYNK_WRITE(V1)
Pseudo Code:
BLYNK_WRITE(V1)
if (param.asInt() )
execute command 1;
else if (param.asInt() )
execute command 2;

I know that from my pseudo code is missing the logic to implement the toggling of the commands but that is my problem…

Thanks

why this is does not work???

status is a boolen global value initially has LOW

  BLYNK_WRITE(V1)
  {
    if (param.asInt() && status == LOW) {
    command 1;
    status = HIGH;
    } else {
    command 2;
    status = LOW;
      }
  }

i found my bug, it was the double == instead of single = I corrected my code above

STILL DOES NOT WORK…

bool / boolean is true or false not LOW.
