More tests for DF Player

Today we tried to solve the issue we had last week to make the DFplayer work with the ESP32:

following this tutorial : (8650) DFPlayer Mini Interface with ESP32: Audio Playback Tutorial | Add voice to ESP32 - YouTube

here is the code from the video:

#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"

// Use pins 2 and 3 to communicate with DFPlayer Mini
static const uint8_t PIN_MP3_TX = 25; // Connects to module's RX 
static const uint8_t PIN_MP3_RX = 27; // Connects to module's TX 
SoftwareSerial softwareSerial(PIN_MP3_RX, PIN_MP3_TX);

// Create the Player object
DFRobotDFPlayerMini player;

void setup() {

  // Init USB serial port for debugging
  Serial.begin(9600);
  // Init serial port for DFPlayer Mini
  softwareSerial.begin(9600);

  // Start communication with DFPlayer Mini
  if (player.begin(softwareSerial)) {
   Serial.println("OK");

    // Set volume to maximum (0 to 30).
    player.volume(20);
    // Play the first MP3 file on the SD card
    player.play(1);
  } else {
    Serial.println("Connecting to DFPlayer Mini failed!");
  }
}

void loop() {

 
   }

However, I get an error message :

I tried another code I found in the comments:

#include "DFRobotDFPlayerMini.h"

DFRobotDFPlayerMini player; // Create the Player object

void setup() {

  Serial.begin(9600); // Init USB serial port for debugging

  Serial2.begin(9600); // Init serial port for DFPlayer Mini

  // Start communication with DFPlayer Mini

  Serial.println("Connecting to DFplayer");

  while (!player.begin(Serial2))

  {

      Serial.print(".");

      delay(1000);

  }

  Serial.println(" DFplayer connected!");

  player.volume(20); // Set volume to maximum (0 to 30).

}


void loop() {

    player.play(1);

    delay(3000);

    player.play(2);

    delay(3000);

    player.play(3);

    delay(3000);

   }

but I get the same error message.

SO, I tried another code from another source :

#include <DFPlayer_Mini_Mp3.h>


#include <SoftwareSerial.h>

#include <DFRobotDFPlayerMini.h>


SoftwareSerial mySerial(25, 27); // RX, TX

void setup() {
    mySerial.begin(9600);
    mp3_set_serial(mySerial);
    mp3_set_volume(15);       // fixe le son (30 maximum)
    mp3_set_EQ(0);            // equalizer de 0 Ã 5
}

void loop() {
    mp3_play();  // joue mp3/0001.mp3
    delay(5000); // pause de 5 secondes

}

and another one:

#include <SoftwareSerial.h>
#include <DFPlayer_Mini_Mp3.h>

SoftwareSerial mySerial(25, 27); // RX, TX

//
void setup () {
  Serial.begin (9600);
  mySerial.begin (9600);
  mp3_set_serial (mySerial);  //set softwareSerial for DFPlayer-mini mp3 module 
  mp3_set_volume (15);
}


//
void loop () {        
  mp3_play (1);
  delay (6000);
  mp3_next ();
  delay (6000);
}

However, the libraries involved might only work for Arduino and give this type of error message with the ESP32:

Then, I tried reinstalling the libraries, re-setting up the ESP32, and did all the updates.

But nothing works I still get this error message:

DEBRIEF :

I still have the same error message, the ESP32 set-up does not seem faulty, the last 2 libraries don't work for ESP32, something is still not clear in the first 2 codes
