Example
In this example, we connect Ameba to WiFi and use Ameba as server to
send message to connected client.
First, open
“File” → “Examples” → “WiFi” → “WiFiWebServer”
In the sample code, modify the highlighted snippet and enter the
required information (ssid, password, key index) required to connect to
your WiFi network.
Upload the code and press the reset button on Ameba. After connecting to
WiFi, Ameba starts to run as server. The IP of the server is shown in
the serial monitor, and port is 80.
We connect to the server in a browser, and we can see the data sent
from the server.
