  • ESP32-A2DP

    A Simple ESP32 Bluetooth A2DP Library (to implement a Music Receiver or Sender) that supports Arduino, PlatformIO and Espressif IDF

    • I recently discovered that the ESP32 could be used to receive audio via Bluetooth and since I'm using one as part of my build anyway (for controlling peripherals and LED outputs) I was thinking to just use the ESP32's onboard Bluetooth rather than a dedicated chip/module. After looking through some example code and the ESP32-A2DP library, I feel confident that this would work but is anyone able to see any caveats in doing this other than not being able to support aptx?
