Description

In this project, we will use Ameba to scan available Wifi hotspots in the surroundings, and prints the SSID, encryption type, signal strength information of each detected hotspots.

Details

Ameba RTL8722DM is a low-power dual-band WLAN and 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.

Programming

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".

Final Result

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.
