I2S problem causing constant reboots

mooballs commented 10 months ago

Problem Description

Previously working code that I have come back to after 6 months or so now just reboots. Have tried different boards, cables, flash modes, esp core versions (2.0.11, 2.0.14, 3.alpha). Used the latest version of Audio Tools, plus tried some older ones.

Please Help!

Device Description

ESP32 Dev Module

Sketch

#include <AudioTools.h>

#include "AudioLibs/AudioA2DP.h"
#include "AudioConfigLocal.h"
#include "BluetoothA2DPSink.h"

BluetoothA2DPSink a2dp_sink;
I2SStream i2s;
//A2DPStream in;
Equilizer3Bands eq(i2s);
//StreamCopy copier(eq, i2s); // copy in to equilizer
ConfigEquilizer3Bands cfg_eq;

// Potentiometer is connected to GPIO 35
const int potPin = 35;
// variable for storing the potentiometer value
int potValue = 0;

void read_data_stream(const uint8_t *data, uint32_t length) {
  eq.write(data, length);
}

// Arduino Setup
void setup(void) {

  Serial.begin(115200);

  AudioLogger::instance().begin(Serial, AudioLogger::Info);

  //i2s_out esp32 external DAC
  auto config = i2s.defaultConfig(TX_MODE);
  config.pin_bck = 26;
  config.pin_ws = 25;
  config.pin_data = 23;
  config.sample_rate = a2dp_sink.sample_rate();
  config.channels = 2;
  config.bits_per_sample = 16;
  i2s.begin(config);

  cfg_eq = eq.defaultConfig();
  cfg_eq.setAudioInfo(config); // use channels, bits_per_sample and sample_rate from kit

  cfg_eq.gain_medium = 1.0;
  cfg_eq.gain_high = 1.0;
  eq.begin(cfg_eq);

  // register callback
  //a2dp_sink.set_pin_config(my_pin_config);
  a2dp_sink.set_stream_reader(read_data_stream, false);

  // Start Bluetooth Audio Receiver
  a2dp_sink.set_auto_reconnect(true);
  a2dp_sink.start("Poo");  //bluetooth name

}

// Arduino loop
void loop() {
  //copier.copy();
  //delay(100);
  potValue = float(analogRead(potPin)) / 4095;
  Serial.println(potValue);
  cfg_eq.gain_low = potValue;
  delay(500);
}

What is your development environment

Arduino 2..2.1 and 1.8

I have checked existing issues, discussions and online documentation

[X] I confirm I have checked existing issues, discussions and online documentation

As you can see, the issue comes from the missing sample rate: either assign 44100 or open a2dp first, in order to make it available

I wondered about that but just panicked as it had worked previously, many thanks.
