Synchronization of app with blynk console and phone app

my problem is my phone app and console and esp32 connected on same router but the values change on arduino esp32 and on console but it cannot change by phone blynk app ,but the app on phone display change value by the blynk

I don’t really understand your explanation of the issue, so more explanation is required.
We also need to see you full sketch (as text, with triple backticks at the beginning and end of the code.
Triple backticks look like this:

Copy and paste these if you can’t find the correct symbol on your keyboard.

You also need to post your serial monitor output - also as text with triple backticks.

BTW, the “Projects made with Blynk category is intended for users to showcase their projects. In your case you should have chosen the “Need help with my project” category. I’ve changed it to the correct category.


#define BLYNK_TEMPLATE_ID "TMPL66dw15J5h"

#define BLYNK_TEMPLATE_NAME "slider"

#define BLYNK_AUTH_TOKEN "KzpFJpu4ELVwpaRGwkcU-MNFPOn-H-zd"

#include <WiFi.h>

#include <WiFiClient.h>

#include <BlynkSimpleEsp32.h>

// Your WiFi credentials.

// Set password to "" for open networks.

char ssid[] = "Mobile networks";

char pass[] = "";


int value = param.asInt();

Serial.print("Received value: ");



void setup()


// Debug console


Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass);


void loop()



when i move the slider from the app the values cannot change on arduino and not same movement of slider widget on occurs on blynk console/ blynk website ,but when i change slider widget from blynk console/blynk website then the values change on arduino and the change value show on blynk app

Despite me giving you triple backticks to copy/paste, you’ve chosen to use different characters, which don’t work.

Please edit your post, using the pencil icon at the bottom, and replace your characters with triple backticks.


So, instead of taking onboard this suggestion…

You’ve decided to post a screenshot of a small part of your serial output instead.

I think it would be helpful if you scared screenshots of the device and widget setup in the Blynk app, along with details of which app version you are using.
