My project requires a Bluetooth A2DP Sink that is the fed to the Teensy 4 via I2S. I'm leaning towards an ESP32 chip connected to the Teensy for both control over its Bluetooth pairing functions, as well as input of it's bluetooth audio.

- There is sample code in the ESP32 API.
- There is sample code in the ESP32 Mp3 Decoder which also shows some hardware pin-outs for connecting the ESP32 to I2S.

Are there any projects that are doing this that I should look at? Since the new Teensy 4 has some additional I2S data lines, I'm looking to add Bluetooth Audio to my project and send the data to the Teensy via I2S.
