ESP32-C6, issues with Bluetooth

[Gob2003]

Hello to all!

I am in a school project that requires Bluetooth and this is my project resumed shortly: I am making my own MP3, of course, I will be using an ESP32 to make my project working. I tested my buttons, functional, the screen is also functional, but I can't make the Bluetooth working (BLE).

I tried those libraries: Esp32 BLE Arduino and ArduinoBLE.

The first step I did was to run an example just to see how it works, but I have this issue when using Esp32 BLE Arduino:

And here's the code:

*/

#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>

int scanTime = 5; //In seconds
BLEScan* pBLEScan;

class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
    void onResult(BLEAdvertisedDevice advertisedDevice) {
      Serial.printf("Advertised Device: %s \n", advertisedDevice.toString().c_str());
    }
};

void setup() {
  Serial.begin(115200);
  Serial.println("Scanning...");

  BLEDevice::init("");
  pBLEScan = BLEDevice::getScan(); //create new scan
  pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks());
  pBLEScan->setActiveScan(true); //active scan uses more power, but get results faster
  pBLEScan->setInterval(100);
  pBLEScan->setWindow(99);  // less or equal setInterval value
}

void loop() {
  // put your main code here, to run repeatedly:
  BLEScanResults foundDevices = pBLEScan->start(scanTime, false);
  Serial.print("Devices found: ");
  Serial.println(foundDevices.getCount());
  Serial.println("Scan done!");
  pBLEScan->clearResults();   // delete results fromBLEScan buffer to release memory
  delay(2000);
}

I am not sure what is wrong too... I require help please.

Kind regards.

just remove the libary from arduino ide which => "BLEUtils.h"
