### Audio Data Path
|
||||||
|
|
||||||
|
ESP32 supports two types of audio data path: PCM and HCI.
|
||||||
|
|
||||||
|
- PCM : When using PCM, audio data stream is mapped to GPIO pins and you should link these GPIO pins to a speaker via I2S port.
|
||||||
|
- HCI : When using HCI, audio data stream will be transport to HF unit app via HCI.
|
||||||
|
|
||||||

||||||
- Enable `Classic Bluetooth`, `Hands Free/Handset` and `Aduio Gateway` under `Component config ---> Bluetooth ---> Bluedroid Options`.
|
|
||||||
- When using PCM as the data path and this example configures PCM audio data to GPIO pins. You can link the GPIO pins to a speaker via I2S port. PCM data path does not support mSBC codec but CVSD codec.
|
|
||||||
- When using HCI data path, ESP32 support both CVSD and mSBC codec.
