Ok thanks for clarifying. But then how do I set up the pin numbers and sample rate configuration etc for i2s? Sorry if this is a stupid question.

Also, I was manually setting up i2s and continuous adc for testing purposes to get something working. My actual goal is to use the bluetooth classic hfp ...

You do not have to do anything with I2S if you use that driver; it handles the fact that on the ESP32 the data transfer happens to go through I2S entirely for you.


Hi @ESP_Sprite,

Nice to see a fellow Tweaker here ;) I have to say I'm really confused whether i2s dac is possible in esp-idf 5.x ...
