[SOLVED] Read Step/Slider Widget during Setup

Solved
1

I would like to read the value of the Step Widget at the start without having to physically step the widget on my phone.

Example:

If my Step Widget is set at say 20, now if my ESP8266 has a cold power start I want it to automatically read the value “20” This would apply to a Slider Widget as well

How would I implement the code?

Thanks

int someValue;
BLYNK_WRITE(V0) 
{
   someValue = param.asInt();
}

And in setup add
Blynk.syncVirtual(V0);

Edit virtual pin for your setup

Thanks so much, that worked.

I’m interested in doing the same thing, but this didn’t work for me. Everything runs well and outputs to Serial when I step V3 and V5. But when I hit the “start” button on pin V6, I want it to already have the values from V3 and V5.

#define BLYNK_USE_DIRECT_CONNECT
#define BLYNK_PRINT Serial

// You could use a spare Hardware Serial on boards that have it (like Mega)
#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(2, 3); // RX, TX

#define BLYNK_PRINT DebugSerial
#include <BlynkSimpleSerialBLE.h>

char auth[] = "...";

int travelTime;
int motorSpeed;

BLYNK_WRITE(V3)
{
  travelTime = param.asInt(); // assigning incoming value from pin V1 to a variable
  // You can also use:
  // String i = param.asStr();
  // double d = param.asDouble();
  Serial.print("Travel Time: ");
  Serial.println(travelTime);
}

BLYNK_WRITE(V5)
{
  motorSpeed = param.asInt(); // assigning incoming value from pin V1 to a variable
  // You can also use:
  // String i = param.asStr();
  // double d = param.asDouble();
  Serial.print("Motor Speed: ");
  Serial.println(motorSpeed);
}

BLYNK_WRITE(V6)
{
  int pinValue = param.asInt(); // assigning incoming value from pin V1 to a variable
  // You can also use:
  // String i = param.asStr();
  // double d = param.asDouble();
  Serial.print("START!      ");
  Serial.print("     Travel Time: ");
  Serial.print(travelTime);
  Serial.print("     Motor Speed: ");
  Serial.println(motorSpeed);
}

void setup() {
    Serial.begin(9600);
    Blynk.begin(Serial, auth);

    Blynk.syncVirtual(V3);
    Blynk.syncVirtual(V5);           
}

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

@ChrisPomerleau You should really start your own topic instead of a “Me Too” addon. Your situation could be completely different… as in… aren’t you running via Bluetooth? because Blynk.syncVirtual(Vx);requires a server connection.
