The factory default firmware is Bluetooth speaker, which uses A2DP protocol to transmit audio data（call reception is not supported). After power on, the red LED will be displayed. When the connection with Bluetooth device is established, the LED will turn green. At this time, the sound can be output through atom echo. 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. See the following links for the source code of factory firmware and bin file, where the BIN file burning address is 0x0000.
