Error with esp32 and BluetoothSerial.h library

[Aleja14]

After loading a code with the BluetoothSerial.h library it does not work, a light flashes all the time and in the console I get this error:

Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.

This is the arduino code (example BluetoothSerial):

Code: Select all

#include "BluetoothSerial.h"

#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it
#endif

BluetoothSerial SerialBT;

void setup() {
  Serial.begin(115200);
  SerialBT.begin("ESP32test"); //Bluetooth device name
  Serial.println("The device started, now you can pair it with bluetooth!");
}

void loop() {
  if (Serial.available()) {
    SerialBT.write(Serial.read());
  }
  if (SerialBT.available()) {
    Serial.write(SerialBT.read());
  }
  delay(20);
}
