No output with example basic-a2dp-spdif.ino #1493
-
|
I'm trying to get the example file "basic-a2dp-spdif.ino" to work. Hardware: Environment: When compiling the example sketch without any changes, I get a compilation error: I have to swap lines 9 and 10 (include "AudioTools.h" before "BluetoothA2DPSink.h") to compile the file without errors. Uploading works just fine, but I get the follwing error message when running the program (changed to AudioLogger to Debug level to get the full output after I had no sound): After connecting a device an starting playback, I get I also tried using PlatformIO to get the example to work. I don't get compilation errors here, but the error message when running the program is the same. Any other example using SPDIF as output works fine. I also tried the "base-generator-a2dp.ino" to check if I had a general problem with A2DP and it works just as expected. Is there anything I'm missing in my approach? |

I changed the output to analog (44.1kHz, stereo, 16 bit) and I get "something that sounds similar to what I'm playing". Sounds a bit as if there are samples missing. I have similar distortions with the generator-analog example so this might be related to my wiring. |

With the latest version of A2DP, it is possible to define the output. #include "AudioTools.h"
#include "BluetoothA2DPSink.h"
AudioInfo info(44100, 2, 16);
SPDIFOutput spdif;
BluetoothA2DPSink a2dp_sink(spdif);
void setup() {
Serial.begin(115200);
AudioLogger::instance().begin(Serial, AudioLogger::Warning);
// setup output
auto cfg = spdif.defaultConfig();
cfg.copyFrom(info);
cfg.buffer_size = 384;
cfg.buffer_count = 30;
cfg.pin_data = 23;
spdif.begin(cfg);
// Start Bluetooth Audio Receiver
a2dp_sink.start("a2dp-spdif");
}
void loop() {
delay(100);
} |

this is code: /**

You forgot to activate the ESP32 Logger in the Arduino Tools menu! |

Strange: I have never seen esp_bluedroid_init() fail! |

ESP32 wrover dev with built-in camera as pictured above. now the camera is removed. at the bottom of the board it says esp32 wrover dev v1.6

What is your ESP32 Core Version ? In Arduino go to Tools -> Boards -> Board Manager and type "ESP32" You will the see e.g. esp32 by Espressif version 2.0.11 The actual version is 2.0.15! |

You don't have enough RAM: try to reduce the cfg.buffer_count! |

i try to set cfg.buffer_count = 20; it just doesn't work like before. i try reduce buffer_size: 128 Doesn't work 😫 ... abort() was called at PC 0x4017f2a9 on core 1 |

I tend to think that this is a problem with your hardware. |

For me both buffer_count 30 and PSRAM active and not active is working. But I noticed that reducing the buffer_count gets overwritten by the default value of 30! |

Yaa, it works 😁 This is the video when i tried it: |
