Hmm, that looks interesting, I've just ordered one...

I've worked on this in the past, here are the results of inline c code :

#If C
#include <DFPlayer_Mini_Mp3.h>

void Mp3_set_serial(B4R::Object* o) {
   SoftwareSerial* soft = (SoftwareSerial*)b4r_main::_softserial->getStream()->wrappedStream;
   mp3_set_serial(*soft);
}

void Mp3_send_cmd2(B4R::Object* o) {
mp3_send_cmd(b4r_main::_cmd, b4r_main::_arg);
}

//void Mp3_send_cmd(B4R::Object* o) {
// mp3_send_cmd(b4r_main::_cmd);
//}

void Mp3_set_volume(B4R::Object* o) {
mp3_set_volume(b4r_main::_volume);
}

void Mp3_next(B4R::Object* o) {
mp3_next();
}

void Mp3_prev(B4R::Object* o) {
mp3_prev();
}


void Mp3_sleep(B4R::Object* o) {
mp3_sleep();
}

void Mp3_reset(B4R::Object* o) {
mp3_reset();
}

void Mp3_pause(B4R::Object* o) {
mp3_pause();
}

void Mp3_random_play(B4R::Object* o) {
mp3_random_play();
}

void Mp3_stop(B4R::Object* o) {
mp3_stop();
}

void Mp3_play(B4R::Object* o) {
mp3_play();
}

//void Mp3_play_num(B4R::Object* o) {
// mp3_play(b4r_main::_num);
//}

void Mp3_single_play(B4R::Object* o) {
mp3_single_play(b4r_main::_num);
}

void Mp3_single_loop(B4R::Object* o) {
mp3_single_loop(b4r_main::_state);
}

void Mp3_get_tf_sum(B4R::Object* o) {
mp3_get_tf_sum();
}

void Mp3_get_tf_current(B4R::Object* o) {
mp3_get_tf_current();
}

void Mp3_get_state(B4R::Object* o) {
mp3_get_state();
}

#End If

This is how it is used, from remote :

Sub Astream_NewData (Buffer() As Byte)
    Private st As String
    Log(st)
    If Buffer(0) = 0x76 Then  ' "v"
        Private buf(2) As Byte 
        bc.ArrayCopy2(Buffer,1,buf,0,2)
        st = bc.StringFromBytes(buf)
        Log(st)
        Volume = st
        RunNative("Mp3_set_volume", Null)
               
    Else   
        st = bc.StringFromBytes(Buffer)

        Log(st)
       
        Select st
           
            Case "Cont"
                State = False

                Log("song ",Arg)
                Cmd = 0x03

Can you share DFPlayer_Mini_Mp3.h?

Or port this library

[Ilya G.]

Can you give a full project and a connection photo please?

 

[derez]

Attached find B4A and B4R applications. the player is operated by connections to pins 3 - rx and 4 - tx (and of course vcc, gnd and the two spk pins), because it is controlled by phone with BT.

Here's the problem, I tried to run this code on ESP-12e

It can work, just feed the player by 5v and use logic converters on the rx tx pins to 3.3v
Also you have to put the song files in the sd card of the player...
This is for Wifi:

Private Sub AppStart

   Serial1.Initialize(115200)
   Log("AppStart")


   If wifi.Connect2("xxxxx","xxxxxxxxx") Then  ' change to your wifi
        server.Initialize(55055, "server_NewConnection")
        server.Listen
        Log("Waiting for connection.")
        Log("My ip: ", wifi.LocalIp)
    Else
        Log("Failed to connect to Wifi.")
    End If
    timer1.Initialize("timer1_Tick", 2000)


    Softserial.Initialize(9600,d1.d3,d1.d4) 'in wemos - pins 8 rx,9 tx or any other pair
    Softserial.Listening = False
 
    pstream.Initialize(Softserial.Stream, "pstream_NewData", "pstream_Error")
