Use NTPClient Library to Obtain Local Time

Ameba RTL8722DM

Ameba RTL8722DM is a low-power dual-band WLAN and BLE(Bluetooth Low Energy) SoC by Realtek. The RTL8722DM also include memory for Wi-Fi protocol functions and application making it simple for anyone to develop various kind of IoT applications. At the same time it has a wide range of peripheral interfaces. With all these interfaces, it can connect to most of the electronics components like LEDs, temperature and humidity sensors, and so on.

In this example, we use an NTP client to sync with NTP servers using UDP and keep track of time locally. Open the example. "File"→"Examples"→"NTPclient"→ "Advanced"

Modify the highlighted code section (ssid,password) to connect to your WiFi network.

Compile the code and upload it to Ameba. After pressing the reset button, Ameba Connects to WiFi, gets the UTC time from the NTP server, amd prints out the current time with time zone offset to the serial monitor.
