Due to hardware limitations, ESP32 does not support such functions of Bluetooth LE 5.0 as 2M PHY, LE Long Range, and ADV Extensions. It is also worth mentioning that the combination of Bluetooth and Mesh networking is expected to become a key technology for the Internet of Things.. Feb 16, 2022 · In this part of the ESP32 audio project, the internet radio built in Part I gets an extension: bluetooth audio streaming. The hardware from the first part is used, i.e. an M5StickC plus with an I²S DAC. The software includes an additional library, the ESP32-A2DP library which allows to turn the ESP32 into a bluetooth audio (A2DP) sink..
