Before starting

The clock can synchronize time via the internet if a DS3231 time module is not installed. If the DS3231 time module is connected to the circuit board, an internet connection is not required.

To establish an internet connection, the WIFI station name and password must be input into the clock's software to connect to a WIFI router.

These WIFI credentials need to be entered only once; they will be saved in the microprocessor's memory.

For convenience, it is recommended to use a phone or tablet with a Bluetooth communication app to input the WIFI details into the clock.

For downloading a Bluetooth UART serial terminal app, use BLESerial nRF or BLE Serial Pro for iOS, and Serial Bluetooth Terminal for Android.
