void loop()
Hello, please I need help, Blynk App sows that was not online yet. below is my NodeMcu Code
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SoftwareSerial.h>
char auth[] = "Y12vESUKNP5YEa7pmHwA_fbwGda1fAKB";
// Your WiFi credentials.
char ssid[] = "speeder";
char pass[] = "Billions@";
BlynkTimer timer;
String myString; // complete message from arduino, which consists of sensors data
char rdata; // received charactors
int firstVal, secondVal,thirdVal; // sensors
int led1,led2,led3,led4,led5,led6;
// This function sends Arduino's up time every second to Virtual Pin (1).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V1, millis() / 1000);
}
void setup()

// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
