Users can Turn on the power, and the indicator light is red. Turn on the Bluetooth device and search for nearby devices. The Bluetooth device with the name of M5_SPEAKER_T1 is ATOM ECHO. Click connect or pairing, ATOM ECHO will send Bluetooth pairing request, confirm pairing to establish Bluetooth connection, at this time, the indicator light turns green to indicate that the connection is normal. Once the connection is established successfully, atom echo can be used as an audio playback device.
