I really wanted to listen to the radio while making breakfast and drinking morning coffee without having to fiddle with my phone. While at it, why not occasionally play media over bluetooth as well. The ESP32 reads audio files from the SD card and uses an I2S audio libraryto send the I2S data stream to the MAX98357A (or two of them for stereo.) From there it is decoded automatically and audio.. To send the Bluetooth audio from the ESP32 to the stereo decoder we are going to use a method of digital communication called I2S. The stereo decoder will take this digital signal and turn it into an analogue signal that can be plugged into a speaker or HiFi. I2S only requires 3 wires and is reasonably straightforward to understand. The bit clock (bclk) line turns high and low to indicate a. The ESP32-LyraT is a hardware platform designed for the dual-core ESP32 audio applications, e.g., Wi-Fi or Bluetooth audio speakers, speech-based remote controllers, connected smart-home appliances with one or more audio functionality, etc. The ESP32-LyraT is a stereo audio board Making an ESP32 Bluetooth Speaker. Post by chefboyrd » Tue Feb 13, 2018 1:48 am . Hello, Newbie here. I'm currently looking to create a bluetooth speaker streaming music from an iPhone using the ESP32. I've seen MrBuddyCasino's ESP32 Web Radio example but I'm looking to program this in C. Would anyone be able to point me in the right direction on how I might do this? Not sure how to implement.

My initial design was to have esp32 Vroom and anothe BT audio receiver. However, it is silly to have two bluetooth hardware, where esp32 Vroom itself is capable of handling BT audio streaming (if I am not wrong). I have to confess that at the stage, I presume developing audio streaming is a big undertaking and it is also reinventing the wheels too since it is very common. Feel free to comment.
