How to deal with Blynk.syncVirtual(xx)?

Hello !

I have a problem with the synchronization of virtual pins.

I use an Arduino Nano with a HC08 BLE module and a direct connect with iOS 14.0 to deal with strip led (on/off, some animation, and custom RGB color with sliders)

I can sync all the widget on connection, the BLYNK_WRITE(XX) is never call after the sync.
The widget are in the right position, but I have to click button or slide a slider tu trigger the BLYNK_WRITE(XX).

My virtualpin V1 is a menu with some animation.
I want to restore the last animation when i’m connect to Blynk.

My question is: It’s possible to put my strip led to the last state without touch manually a widget?

here is my code (simplified):


#include <BlynkSimpleSerialBLE.h>
BlynkTimer timer;

// RGB Lights
#include <Adafruit_NeoPixel.h>
#define NUM_LEDS 36
#define PIN 6

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "xxx"; // Nano

  Blynk.syncVirtual(V0, V1);;

void setup()
  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  for (int x = 0; x < NUM_LEDS; x++) {
    strip.setPixelColor(x, 50, 0, 0);
  Blynk.begin(Serial, auth);

void loop()

void activity(int activity_button) {
	// Switch / case to select activity

  Serial.println("CALL V0");
  if (param.asInt()) {
    lamp_on = 1;
  else {
    lamp_on = 0;

BLYNK_WRITE(V1) { //Activity slider
  Serial.println("CALL V1");
  current_activity = param.asInt();

In the Serial monitor I just show CONNECTED from BLYNK_CONNECTED() But I never show my CALL from BLYNK_WRITE(XX).

Any suggestion??

Thank you !
