Safety stop of MP3 player

[hash6iron]

Hello.

I'd like to launch a question. How Can I stop saftly the MP3 player? When I try to exit of streaming copy loop, the ESP32 Audiokit reboot, then I think that the problem is I don't end saftly the .copy streaming process.

Can someone help me?

Rebooting...```

[pschatzmann]

The player follows the Arduino conventions and if you double check the class documentation there is an end() method!
However you have a different issue: somehow your heap got corrupted or your freeing the same memory multiple times!

I do not recommend to allocate and delete objects dynamically on Microcontrollers: sooner or later you risk to run into memory fragmentation issues...

[hash6iron]

In the loop where the player is running there is not dynamic objects.

yes, I had used .end() but this not fix the problem. Something relationed with streaming causes the reboot. The issue occurs into the function where I have the loop and after the player.copy() left to work because forzed to exit loop to end the function and close the mp3 player, even the problem ocurrs without play de file, only coming in and out of the loop reboot the Audiokit.

[hash6iron]

I have checked the function after removing all about MP3 player and the Audiokit doesn't reboot, then the problem is in the MP3 player. I try to delimit it and talk to you again.

NOTE: The same behaviour occurs with the WAV player.

[pschatzmann]

Double check if this is helping ?

[hash6iron]

Yes, after comment these lines all work fine, but, is a bug? Will there an update now?

[pschatzmann]

Yes, it is a bug that has been corrected with the commit that I sent you...

[hash6iron]

Great! I'm going to update then.

Thanks so much for your dedication.
