PHPoC WiFi Shield for Arduino provides an RTC function for time information. With the built-in battery mounted on the shield, it maintains the time information even when the power is turned off. Therefore, time setting requires only once.
Because of the built-in battery charging system, the battery is charged whenever the power is connected to the shield. However, if you do not connect power to shield for a long period (about 30 days), the battery is discharged and time information may be initialized.
Connect the shield to the Network, following the instructions from Connecting to Network.
Connect SETUP page of the built-in web server of the product with your smartphone or PC.
Click "TIME SYNC" to synchronize the current time of the shield with your smartphone or PC.
Make sure that the current time and the time on your smartphone or PC is synchronized with the shield.
