myMp3.Play() works but myMp3.Loop() dosn't

myMp3.Play() works but myMp3.Loop() at the same place dosn't

[PowerBroker2]

It works for me (just tested on my Mega).

Can you post your code in tags along with a detailed description of the file structure and filename list on your SD card?

This is the full code to this day. But it's not finished yet

the file structure is: SD/mp3/0001Opening.mp3 0002Humming.mp3 0003Closing.mp3

[oOJoshOo]

Its running on an arduino nano

[PowerBroker2]

Do you have a simpler example that I can run to test?

[oOJoshOo]

Not yet, tomorrow I'll be working on a simpler sketch.

[oOJoshOo]

Sry for the late answer, i have the same problem with your example scetch. The myMp3.play works but the loop dosent

#include <DFPlayerMini_Fast.h>

#if !defined(UBRR1H)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(7, 8); // RX, TX
#endif

DFPlayerMini_Fast myMP3;

void setup()
{
  Serial.begin(115200);

#if !defined(UBRR1H)
  mySerial.begin(9600);
  myMP3.begin(mySerial);
#else
  Serial1.begin(9600);
  myMP3.begin(Serial1);
#endif

  Serial.println("Setting volume to max");
  myMP3.volume(30);
  delay(20);

  Serial.println("Playing track 1 for 5 sec");
  myMP3.play(1);
  delay(5000);

  Serial.println("Sleeping for 5 sec");
  myMP3.sleep();
  delay(5000);

  Serial.println("Waking up");
  myMP3.wakeUp();

  Serial.println("Looping track 1");
  myMP3.loop(2);
}

void loop()
{
  //do nothing
}

[oOJoshOo]

I found out, thet if I play track 2 and loop track 1 everything works. could it may be that there is a length limit for loop?

[oOJoshOo]

ok track 2 doesn't want to loop even if it is exactly as long as track 1

[oOJoshOo]

here are the sounds i'm using Sounds.zip

[PowerBroker2]

delete these lines and see if it helps:

  Serial.println("Sleeping for 5 sec");
  myMP3.sleep();
  delay(5000);

  Serial.println("Waking up");
  myMP3.wakeUp();

[oOJoshOo]

Unfortunately, that didn't fix the problem either. In addition, these lines are not present in my actual code.

[PowerBroker2]

This works perfectly for me, as long as I'm not using your mp3 files:

#include <DFPlayerMini_Fast.h>

#if !defined(UBRR1H)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(7, 8); // RX, TX
#endif

DFPlayerMini_Fast myMP3;

void setup()
{
  Serial.begin(115200);

#if !defined(UBRR1H)
  mySerial.begin(9600);
  myMP3.begin(mySerial);
#else
  Serial1.begin(9600);
  myMP3.begin(Serial1);
#endif

  Serial.println("Setting volume to max");
  myMP3.volume(30);
  delay(20);

  Serial.println("Playing track 1 for 5 sec");
  myMP3.play(1);
  delay(5000);

  Serial.println("Looping track 1");
  myMP3.loop(2);
}

void loop()
{
  //do nothing
}

I think the humming track is too small for the DFPlayer to recognize or isn't in the right format for some reason. I'd suggest using clips that are at least a second long AND use wav files. Using wav files will decrease the amount of time in between calling play() or loop() and the sound actually playing (mp3 files need to be decompressed before playing unlike wavs).

I'd love to see the lightsaber once you're done with it - cool project idea.
