There are lots of good example out there that takes a http based audio stream from the internet via WIFI and output audio via I2S to a codec/audio amplifier. In case you want to use your mobile to source the audio you can use the bt audio sink examble. If you require Wifi one option is to wait for s...

Hi MooaLot Correct design practice would be control volume in as close the speaker as possible - so if your last point of control is an external DAC find out if it has a volume control to offer over I2C. If that is not the case you are back to apply you volume to you PCM sample before you pass them ...

Wau - well designed and impressive feature list

Hi Small Coke I've done that - It is quite easy just wait for i2s_evt.type == I2S_EVENT_TX_DONE using xQueueReceive(i2s_queue, &i2s_evt, portMAX_DELAY); The queue handle you will get from you driver install setup call i2s_driver_install(0, &i2s_config, 10, &i2s_queue); Let me know if you need more l...

No - But
I use it for raw date - amplifier status, audio samples to be displayed on canvas etc. Do not see why it would not work for image data on a specific format as well.

It is a simple mixup of the A2DP and SPP examples from the Bluetooth classics repo. I have coded my stuff in ESP-IDF no...

Hi
Did you try /esp/esp-idf/examples/bluetooth/bluedroid/classic_bt/a2dp_sink
Very simple and works out of the box.
This project from Buddy works out of the box as well.

Hi Akmishra
It is an old project - Not sure it has been maintained vs the new IDFs that has been rolled out. Let me give it a shoot on my setup here - I will let you know. /J
