The programming of the Ameba RTL8722DM can be done using Arduino IDE which makes it very easy to write code and upload code to the Ameba Board.

First, make sure the correct Ameba development board is selected in Arduino IDE: "Tools" -> "Board".

To get the sample code, Go to "File" -> "Examples" -> "AmebaWiFi" -> "ScanNetworks".

Verify and upload the code. Press the reset button on Ameba once the uploading is complete.

Afterwards, you can see the **Scan Network** message appears, with the detected Wifi hotspots and information of each hotspot.
