Notifications from the Notification widget stopped coming. The device worked for several years without problems. Recently I noticed that notifications from several devices stopped coming. I began to check on the test board the simple sketch from the examples for Blynk.notify( “Test notify!” ) and it also does not work. What happened to the Notifications? Help pls!

BR,
Artem.

This is test sketch:

#define BLYNK_PRINT Serial

#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>

char auth[] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

void notifyOnButtonPress()
{
  // Invert state, since button is "Active LOW"
  int isButtonPressed = !digitalRead(2);
  if (isButtonPressed) {
    Serial.println("Button is pressed.");

    // Note:
    //   We allow 1 notification per 5 seconds for now.
    Blynk.notify("Test button is pressed!");
  }
}

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

  Blynk.begin(auth);

  // Setup notification button on pin 2
  pinMode(2, INPUT_PULLUP);
  // Attach pin 2 interrupt to our handler
  attachInterrupt(digitalPinToInterrupt(2), notifyOnButtonPress, CHANGE);
}

void loop()
{
  Blynk.run();
}

I’ve fixed your code by adding triple back-ticks.

You should read this:

The solution is probably to uninstall then reinstall the app.

I reinstalled the blynk application and it all worked. Thanks of coursr, but what made this happen?

I’ve no idea. I’m assuming that it has been caused by an Apple update.
