Materials
- AmebaD [ AMB23 / AMB21 / AMB22 / BW16 / AW-CU488 Thing Plus ] x 1
Example
In this example, the HttpClient library is used to retrieve a webpage using the HTTP protocol.
First, make sure that the correct Ameba development board is selected in “Tools” -> “Board”
Then open “File” -> “Examples” -> “AmebaHttp” -> “SimpleHttpExample”
In the sample code, modify the highlighted section to enter the information required (ssid, password, key index) to connect to your WiFi network.
Upload the code and press the reset button on Ameba once the upload is finished. Open the serial monitor in the Arduino IDE and you can see the information retrieved from the website.
