avrc commands not working

[techexplorers123]

edit: no avrc commands seams to work.
also, forgot to add tryed on android and windows 10 with spotify. Usually Spotify on both windows and android works with the controls of any BT speaker or headphones.
hi,
the play and pause commands from a2dp seams to do nothing.
for now, i am using the boot button for testing.
the button works fine cause pressing it triggers things.
it's the play and pause options that doesn't work
i have no idea how to even begin troubleshooting it.
please help.
in the code, i tested just the pause function only by removing condition checks but that doesn't work either.
here is my code as always:

#include "AudioTools.h"
#include "SPIFFS.h"
#include <OneButton.h>
#include <BluetoothA2DPSink.h>

AnalogAudioStream out;
BluetoothA2DPSink a2dpSink(out);
WAVDecoder wav;
EncodedAudioStream decoder(&out, &wav);
A2DPNoVolumeControl noVolume;
OneButton btn(0, true);

void playEventSound(const String &filename)
{
  File f = SPIFFS.open(filename, "r");
  StreamCopy stat_copy(decoder, f);
  stat_copy.copyAll();
  f.close();
}

void on_connection_state_changed(esp_a2d_connection_state_t state, void *ptr)
{
  if (state == ESP_A2D_CONNECTION_STATE_CONNECTED)
  {
    playEventSound("/connect.wav");
  }
  else if (state == ESP_A2D_CONNECTION_STATE_DISCONNECTED)
  {
    playEventSound("/disconnect.wav");
  }
}

void btnAction()
{
  switch (btn.getNumberClicks())
  {
  case 1:
    if (a2dpSink.is_output_active() == true)
    {
      a2dpSink.pause();
    }
    else
    {
      a2dpSink.play();
    }
    break;
  case 3:
    a2dpSink.stop();
    a2dpSink.start("esp32 player", false);
    break;
  default:
    break;
  }
}

void setup()
{
  btn.debounce(true);
  btn.attachMultiClick(btnAction);
  SPIFFS.begin();
  auto cfg = out.defaultConfig(TX_MODE);
  cfg.use_apll = false;
  out.begin(cfg);
  decoder.begin();
  a2dpSink.set_volume_control(&noVolume);
  a2dpSink.set_volume(150);
  a2dpSink.set_on_connection_state_changed(on_connection_state_changed);
  playEventSound("/poweron.wav");
  a2dpSink.start("esp32 player", true);
}

void loop()
{
  btn.tick();
}

These are AVRC commands and you need to be connected to an application that supports them!
I think you forgot to add some error messages that are issued if you call one of thouse commands w/o beeing connected...

ps.
To investigate what is happening, just activate the logging in the Tools menu.

what are the apps that works with it? I thought spotify works since it works with other bluetooth devices and built in controls on my keyboard.

[pschatzmann]

Yes, I would expect that Spotify should work...

ah my bad. seams like the oneButton lib doesn't register single or double clicks under multiclick. not sure why that's the case, but no one told me about it.
guess i have to change up the code again.
sorry about that. I thought it was the avrc commands cause the triple press to reset connection seams to work. so i thought others are working as well.
since getNumberClicks literally means to get number of clicks not 3 or more clicks normally and it is not mentioned on the sample code or any docs i found for that lib.
Nevver thought of testing it either till you mentioned to add logs.
