• Esp32s ble
• Android 4.4.2
• Blynk server
• Version 1.1.0


#define BLYNK_USE_DIRECT_CONNECT

#include <BlynkSimpleEsp32_BLE.h>

#include <BLEServer.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "X0TJTB-54TVrgIyl-x-SecukBkumRZJc";

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

  Serial.println("Waiting for connections...");

  Blynk.setDeviceName("Blynk");

  Blynk.begin(auth);
}

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

First of all, please edit your post and add triple backticks ``` before and after your whole sketch.

you’re using blynk legacy so you should downgrade the blynk library to version 0.6.1

thanks i will try

Well, you haven’t included any Blynk libraries, and even if you had, I don’t see how this sketch tells the Blynk library to use the ESP32’s BLE port to establish the connection.

I installed both the library and the code is one of the code samples of the blynk library but the problem still persists.

How are you powering your board ?

PeteKnight · July 27, 2022, 11:45am

We don’t want a photo of your serial monitor output, we want the text, formatted with triple backticks the same was as when you post code.

You’ve edited your forts post multiple times since your initial sketch, but I still don’t see how it knows to use the BLE connection - although I’ve never used BLE with Blynk.
