Ameba Arduino: [RTL8195AM] [RTL8710AF] Scan available WiFi hotspots in the surroundings


  • Ameba x 1
  • Antenna x 1


In this example, we use Ameba to scan available WiFi hotspots in the surroundings, and prints the SSID, encryption type, signal strngth information of each detected hotspot.

First, make sure Ameba is selected in Arduino IDE: “Tools” -> “Board” -> “Arduino Ameba”


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.


Code Reference

First we use WiFi.macAddress(mac) to get the MAC address of Ameba:
Then we use WiFi.scanNetworks() to detect WiFi hotspots:
To get information of detected WiFi hotspot:
We use WiFi.SSID(thisNet) to retrieve SSID of a network:
We use WiFi.RSSI(thisNet) to get the signal strength of the connection to the router:
We use WiFi.encryptionType(thisNet) to get the encryption type of the network:

Comparison with Arduino

In the Arduino platform, we need to add an extra WiFi shield to be the WiFi module to realize the WiFi connection. And we have to #include to use SPI to communicate with WiFi module. However, Ameba is already equipped with WiFi module. Therefore, #include is not needed.

Please confirm that QQ communication software is installed
