Simple fault description and troubleshooting

Run light flashing prompt:

1. Start and run 800ms on, 700ms off;
2. The wired network connection is successful (or the WIFI network connection is successful, or the 4G network connection is successful), 160ms on, 140ms off;
3. When entering the MQTT connection state, the blinking speed increases by 5 times on the basis of a successful network connection.

Buzzer prompt:

1. The WIFI/4G/wired network connection is successful, and the buzzer will sound 3 consecutive times, with an interval of about 50ms;
2. The MQTT connection is successful, and the buzzer sounds 3 times in a row, with an interval of about 20ms;
3. After the wired network connection is successful, if an abnormal disconnection occurs, the buzzer will beep for a long time, with an interval of 500ms;
4. The parameter is set successfully, the buzzer will sound twice continuously, and the time interval is about 50ms;
5. After restoring the system settings, the buzzer will sound 3 consecutive times, with an interval of about 80ms;
6. The self-test of the power-on module fails, and there are 2 consecutive beeps, with an interval of 800ms;
7. The self-test of the power-on module is successful, and the buzzer will sound once for 200ms;
8. The connection module is a Rodin module, which sounds 3 times in a row with an interval of 100ms.
