I am currently trying to connect an esp32 to the DFPlayer mini, but i am unable to get a connection to the DFPlayer.
However I am able to play music with the Arduino UNO in the following setup:
with RX resistor (1k, 10k, 100k) and (1k + 680Ohm, as seen in picture)
The following code returns "Connecting to DFPlayer Mini failed!".
I am 100% sure i connected everything right, as it is working with a specific setup on the arduino.
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
// Use pins 2 and 3 to communicate with DFPlayer Mini
static const uint8_t PIN_MP3_TX = 10; // Connects to module's RX
static const uint8_t PIN_MP3_RX = 11; // 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(30);
// Play the "0001.mp3" in the "mp3" folder on the SD card
player.playMp3Folder(1);
} else {
Serial.println("Connecting to DFPlayer Mini failed!");
}
}
void loop() {
}
Nothing works. I even had problems with the arduino. Non of the setups i found online, expect the one from the picture, worked.
Not working. I dont get an "Connecting to DFPlayer Mini failed!" error anymore.
But even if the player is physically not connected the code is not returning an error.
So i assuem its juts dissabling validation

Did you read the thread, which was using a Mega 2560? Or just copy the code without change. My sketch used Serial 1 (pins 18/19) so you’d have to change for your board. If that’s an ESP32 why does your schematic show a UNO?
Also, I’m not clear which version of my sketch you used: the abbreviated one (without the test) or my EDIT? That is your original with my one line correction., so that does include the module test.
