WiFi - Simple Http Server to Receive Data
Materials
- AmebaPro2 [ AMB82 MINI ] x 1
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” -> “SimpleHttpWeb” -> “ReceiveData”:
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.
Code Reference

To get the information of a WiFi connection:
Use WiFi.SSID() to get SSID of the current connected network.
https://www.arduino.cc/en/Reference/WiFiSSID
Use WiFi.RSSI() to get the signal strength of the connection.
https://www.arduino.cc/en/Reference/WiFiRSSI
se WiFi.localIP() to get the IP address of Ameba.

Use server.available() to get a client that is connected to the server and has data available for reading.
https://www.arduino.cc/en/Reference/WiFiServerAvailable
Use client.connected to check whether or not the client is connected.
https://www.arduino.cc/en/Reference/WiFiClientConnected
Use client.println() to print data followed by a carriage return and newline.
https://www.arduino.cc/en/Reference/WiFiClientPrintln
Use client.print() to print data to the server that a client is connected to.
https://www.arduino.cc/en/Reference/WiFiClientPrint
Use client.available() to return the number of bytes available for reading.
