How to Play a single File on Button Press with the new version.

Hey,

I'm rather new to this side of programming. I built a little poc end of last year with your library, and it helped me quite a bit, so thank you very much already.
Now I wanted to refine it, and saw that a lot has changed.

My first code looked like this:

#include "BluetoothA2DPSource.h"
#define TRIGGER_PIN 17
#define LED_PIN 4

extern const uint8_t sound_raw[];
extern const unsigned int sound_raw_len;


int trigger_state;

BluetoothA2DPSource a2dp_source;
SoundData *sound = new OneChannelSoundData((int16_t*)sound_raw, sound_raw_len/2);

void setup() {
  initSerial();
  pinMode(TRIGGER_PIN, INPUT_PULLUP);
  pinMode(LED_PIN, OUTPUT);
  trigger_state = digitalRead(TRIGGER_PIN);
  
  a2dp_source.set_auto_reconnect(true);
  a2dp_source.start("Deimos");
  if (a2dp_source.is_connected()) {
    digitalWrite(LED_PIN, HIGH);
  }
  a2dp_source.set_volume(60);
}

void loop() {
    //Serial.println("Entered Loop");
    if (a2dp_source.is_connected()) {
      digitalWrite(LED_PIN, HIGH);
    } else {
      digitalWrite(LED_PIN, LOW);
    }
    trigger_state = digitalRead(TRIGGER_PIN);
    if (trigger_state == LOW) {
      a2dp_source.write_data(sound);
      delay(110);
    } 
}```

Could you maybe point me in the right direction to get a similar result with v1.8.5. I tried getting a Stream from the Audiotools Library going, but that just gave me a type error, so now I must admit I'm rather confused.

Cheers,

evis

I suggest you read the first 2 chapters of the AudioTools library. This should contain all the necessary basics
