thanks again

in my esp32 , when wifi is connected the blue led is glow , on my esp32 , but i want to flash ( on and off ) it when it connected automatically

John93 · June 16, 2022, 5:47am

Try this

void checkBlynkStatus() { // called every 2 seconds by SimpleTimer

 bool isconnected = Blynk.connected();
 if (isconnected == false) {
   wifiFlag = 1;
   Serial.println("Blynk Not Connected");
   digitalWrite(wifiLed, LOW);
 }
 if (isconnected == true) {
   wifiFlag = 0;
   if (!fetch_blynk_state){
   Blynk.virtualWrite(VPIN_BUTTON_1, toggleState_1);
   Blynk.virtualWrite(VPIN_BUTTON_2, toggleState_2);
   Blynk.virtualWrite(VPIN_BUTTON_3, toggleState_3);
   Blynk.virtualWrite(VPIN_BUTTON_4, toggleState_4);
   Blynk.virtualWrite(VPIN_BUTTON_5, toggleState_5);
   Blynk.virtualWrite(VPIN_BUTTON_6, toggleState_6);
   Blynk.virtualWrite(VPIN_BUTTON_7, toggleState_7);
   Blynk.virtualWrite(VPIN_BUTTON_8, toggleState_8);
   }
   digitalWrite(wifiLed, HIGH);
   Serial.println("Blynk Connected");
   timer.setTimeout(1000, []() 
    {  
    digitalWrite(wifiLed, LOW);
 }
}

John93 · June 16, 2022, 6:28am

You have to change pumpPin[0]

Kamalesh · June 16, 2022, 6:31am

i dont understand

PeteKnight · June 16, 2022, 6:33am

I’m guessing that it’s wifiLed that he wants to flash.

Pete.

John93 · June 16, 2022, 6:39am

That’s Right.

digitalWrite(wifiLed, LOW);

Kamalesh · June 16, 2022, 7:01am

is there any code for this

John93 · June 16, 2022, 7:14am

Go back to post number 24, I’ve modified it.

Kamalesh · June 16, 2022, 7:25am

your massage is " You have to change pumpPin[0] " , i dont understand the meaning of pumpPin[0]

John93 · June 16, 2022, 7:42am

I’m using it in my sketch, it was a mistake .
Post number 24 is ready, you can give it a try.
