Buzzer Tones

The buzzer tones indicate the state of the ESP device and whether it is working properly or not. A single buzzer tone means that the built-in LED is turned on.

5 Buzzer Tones - Startup/Bootup

When the device boots up normally, it will sound “5 fast tones”. If it restarts through the “RST” button, it will sound “5 slow tones”. To reset the ESP device configurations, press the “RST” button 5 times during the slow tones.

Booting up the ESP device through the wired connection (Micro USB Connector) is equivalent to pressing the “RST” button state.

When the device boots up successfully, it will sound a “1 fast tone”. The reset attempts will also go back to zero.
