After spending a lot of time finally I found a repository on GitHub about ESP32-A2DP by Schatzmann. your Bluetooth Speaker with your audio data. ESP32 ESP-IDF Menu. So I started a small “glue” project which provides some Let's make a Bluetooth microphone I said to myself, how hard can it be? A quick thanks to https://www. 7. CVSD is the default setting and is also the widely used codec for voice audio. I tried this example sketch: bt_music_sender_write When plugged into my computer, the ESP32 can be seen and connected to. Default uses 48k single mic and single channel audio data, and it uses FFT to display the music spectrum on the screen and supports multiple animations. Note that streaming to a Bluetooth speaker is not the main purpose and remains experimental, so your mileage will vary. The stereo decoder will take this digital signal and turn it into an analogue signal that can be plugged into a 下面给出一个**“ESP32 充当手机角色、连接蓝牙耳机”的总体方案思路。由于典型蓝牙耳机支持经典蓝牙 (BR/EDR)** 协议栈的 A2DP（高级音频分配） 与 HFP/HSP（免提/耳机） 等 Profile，若要让 ESP32 模拟“手机”功能，则在软件和硬件上需要实现相应的经典蓝牙主机角色，以及音频数据的收发。 I have esp32 with audio pipeline and wireless headphones.
