When the connection with Bluetooth device is established, the LED will turn green. At this time, the sound can be output through atom ech. The LED turns red when disconnected. The firmware is compiled on the esp-idf platform. If senior users need to develop other functions by themselves, they can build the environment according to the official documents of Lexin.
