Kindly Remind

1, The Factory Test firmware is BT 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 BT 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 Espressif. See the following links for the source code of factory firmware and bin file, where the BIN file burning address is 0x0000.

2, Echo already supports HomeAssistant! The latest shipped devices with the sticker ESPHome FW Pre-installed for HomeAssistant have pre-burned ESPHome firmware, users can refer to the following link .Detailed tutorial reference Tutorials for setting up the M5Stack Atom Echo as a voice assistant for Home Assistant.

For those who are not using Home Assistant, you can flash the device with EasyLoader firmware, to resume the device to Factory Test status.

3, G19 / G22 / G23 / G33 has been defined, please do not reuse the above pins, otherwise ATOM ECHO will be damaged.

Note: please avoid such conditions with M5Stack Atom Echo.
