Virtual button and send data do not work together

[Baris_Cetin_Kirca]

I am using esp-01 and uno. I have updated my ESP with ESP8266_NONOS_SDK-master. Everything is great so far. With blynk I can send data with DHT22. and I can view it with iPhon. The problem starts with this point. There is no problem displaying data. but when I want to control the relay or LED with the virtual button, I can not achieve this. no problem just burning virtual buttons and leds. but the two are not together.
Or is it happening?
here is my code…

#include <SimpleTimer.h>
#include <avr/wdt.h>
#include <stdlib.h>
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
#include <DHT.h>
#include <DHT_U.h>
#include <SPI.h>
#include <SoftwareSerial.h>
#define BLYNK_PRINT Serial
#define DHTPIN 12
#define DHTTYPE DHT22
#define RAINPIN A3
SimpleTimer timer;
char auth[] = "eXXX4";
char ssid[] = "denger";
char pass[] = "asdasdas";
SoftwareSerial EspSerial(2, 3); // RX, TX
#define ESP8266_BAUD 9600
ESP8266 wifi(&EspSerial);

// Select your pin with physical button
const int btnPin = 8;
int pin13 = 13;
int phpin = A5;
float t=0;
float n=0;
//float ph=0;
float h=0;
DHT dht(DHTPIN, DHTTYPE);
WidgetLED led1(V29);
WidgetLED led3(V31);


//BlynkTimer timer;

// V3 LED Widget represents the physical button state
boolean btnState = false;
void buttonLedWidget()
{
  // Read button
  boolean isPressed = (digitalRead(btnPin) == LOW);

  // If state has changed...
  if (isPressed != btnState) {
    if (isPressed) {
      led3.on();
    } else {
      led3.off();
    }
    btnState = isPressed;
  }
}

void data(){
  float h = dht.readHumidity();
  float t = dht.readTemperature(); 
  float n = analogRead(A3) / 9.31;
  float ph = analogRead(phpin);
  Blynk.virtualWrite(V20, t);
  Blynk.virtualWrite(V21, h);
  Blynk.virtualWrite(V22, n);
  Blynk.virtualWrite(V23, ph);
  Serial.print("Ph=");
  Serial.println(ph);
   Serial.print("ISI=");
  Serial.println(t);
    Serial.print("NEM=");
  Serial.println(h);
    Serial.print("toprak nem=");
  Serial.println(n);
  
}

void setup()
{
  // Debug console
  Serial.begin(9600);

 
  EspSerial.begin(ESP8266_BAUD);
  Blynk.begin(auth, wifi, ssid, pass);

  // Setup physical button pin (active low)
  pinMode(btnPin, INPUT_PULLUP);

  timer.setInterval(500L, buttonLedWidget);
  timer.setInterval(500L, data);
  
}
BLYNK_WRITE(V4)
{int pinValue = param.asInt(); // Get the state of the VButton
if (pinValue == 0)
{(digitalWrite(pin13,LOW),led1.off());} else {digitalWrite(pin13,HIGH),led1.on();}
}
void loop()
{
  Blynk.run();
  timer.run();
}

BLYNK_WRITE(V4)
{int pinValue = param.asInt(); // Get the state of the VButton
if (pinValue == 0)
{(digitalWrite(pin13,LOW),led1.off());} else {digitalWrite(pin13,HIGH),led1.on();}
}

Is this the function you are having issues with? And what are those issues… doesn’t compile, compiles fine but just no result… partial result… crashes… etc.

I am no good with condensed (shorthand) code, so I have no idea if that is the issue… but I think you need to try breaking it out and testing what does and doesn’t work e.g. the digital pin command & the virtual LED command

Hello
I did some research on the problem yesterday and I organized my coding as follows. It works very well.
I just wonder something.
The virtual button works like this.
BLYNK_WRIT (V2)

{int y2 = param.asInt ();
if (y2> 0) {digitalWrite (role2, HIGH), led2.on ();
else {digitalWrite (role2, LOW), led2.off ();
Serial.print (“Second Button Status:”);
Serial.println (y2);}
“else” (y2) does not work if we do not tell what to do.
so;
BLYNK_WRITE (V2)

{int y2 = param.asInt ();
if (y2> 0) {digitalWrite (role2, HIGH), led2.on ();
Do not you have to work in the form of?
