ESP32 Webradio

> But all at once in one project?

The BiQuad filter will use the most CPU, but its possible. Jakobsen knows about this. I'm not 100% knwoleadable here, but running a SPI display shouldn't use that many resources either. You can look at microwavemont's fork for that.

I compiled ESP32 web radio , I am using bluetooth speaker mode, flashed it to ESP-WROVER_Kit, but in bluetooth controller enable it is failing , here is output

could someone tell me what I need to do , to make it working

-Thanks

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

[barometre]

Hi,

Are there any other working project like this that I can both test A2DP and I2S Dac?

Thanks

[Jakobsen]

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 everyone, I'm getting started with ESP32, and seeing the capabilities it has, was wondering if it would be possible to create a multistereo system using several ESP32 boards, in which one board connects the the audio source ( via bluetooth to phone, pc, etc.) and then through multicasting it shares the audio stream to the other boards.
This way a true 2.1, 3.1, 4.1 o r whatever system can be created, cheaply.

Thanks all guys!

Anyone knows where this project is published - love to build one

Would have liked to see the option to connect to a BT speaker.
