Scanning Wifi Hotspots with RTL8722DM_MINI
We use Ameba to scan available WiFi hotspots in the surroundings, and prints the SSID, encryption type, signal strength information of each detected hotspot.
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.

First, make sure the correct Ameba development board is selected in Arduino IDE: “Tools” -> “Board” ->
Open the “ScanNetworks” example in “File” -> “Examples” -> “AmebaWiFi” -> “ScanNetworks”:
Then upload the sample code and press the reset button on Ameba. Afterwards, you can see “**Scan Networks**” message appears, with the detected WiFi hotspots and the information of each hotspot.
