I'm using a ESP32 as I2S Master to feed a Teensy 4.1 with Bluetooth Audio. It worked fine for more than 100 hours than bluetooth started with noise and failed working 2 hours later. ESP32 can still be programmed but bluetooth is not avaiable any more. Same behavior with a spare part...
提供PCM/I2S 音频接口 蓝牙协议 芯片的蓝牙协议栈支持蓝牙 v4.2 BR/EDR 和 Bluetooth LE 标准。 蓝牙基本框架:蓝牙的基本框架挺复杂的,更多的可以看推荐的第一篇文章的那个博主,他对蓝牙比较专业的,这里用他的一张图来简单叙述蓝牙的基本框架。下面这张图其实在HOST运用层还差一个GAP协议...

There are two main parts: 1.recording from mic and getting data in pdm format 2.proccessing the audio and and sending it to DAC. for the first I'm gonna use I2S.h library in arduino framework. For the second I have two options: using external hardware or bit-banging the pdm audio ...

This example shows how to drive an I2S output device - I've tested this against the MAX98357 breakout board from Adafruit -https://learn.adafruit.com/adafruit-max98357-i2s-class-d-mono-amp There is an example WAV file that can be played or you can play a simple sin wave through the ...
