Hello, I was able to create an access point and create a web server demo to control the RGB on my nano, but I want to create a server that is connected to my Wi-Fi internet as I will be able to use the WiFi.getTime() to get the current Unix time.
So in short, how do I create a web server that is connected to the internet.
Thanks!
there is no dependency between AP mode and Web/TCP Server.
you can run a tcp server on any network.
Can you show me how can I do it?
I used this code to create a webserver with the acsess point. What do I need to change so it will be on my house network?
include <SPI.h>
#include <WiFiNINA.h>
char ssid[] = "yournetwork"; // your network SSID (name)
char pass[] = "yourpassword"; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key index number (needed only for WEP)
int status = WL_IDLE_STATUS;
WiFiServer server(80);
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Access Point Web Server");
pinMode(LEDR, OUTPUT);
pinMode(LEDG, OUTPUT);
pinMode(LEDB, OUTPUT);
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
while (true);
}
String fv = WiFi.firmwareVersion();
if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
Serial.println("Please upgrade the firmware");
}
// by default the local IP address will be 192.168.4.1
// you can override it with the following:
// WiFi.config(IPAddress(10, 0, 0, 1));
// print the network name (SSID);
Serial.print("Creating access point named: ");
Serial.println(ssid);
// Create open network. Change this line if you want to create an WEP network:
status = WiFi.beginAP(ssid, pass);
if (status != WL_AP_LISTENING) {
Serial.println("Creating access point failed");
// don't continue
while (true);
}
// wait 10 seconds for connection:
delay(10000);
// start the web server on port 80
server.begin();
// you're connected now, so print out the status
printWiFiStatus();
}
void loop() {
// compare the previous status to the current status
if (status != WiFi.status()) {
// it has changed update the variable
status = WiFi.status();
if (status == WL_AP_CONNECTED) {
// a device has connected to the AP
Serial.println("Device connected to AP");
} else {
// a device has disconnected from the AP, and we are back in listening mode
Serial.println("Device disconnected from AP");
}
}
WiFiClient client = server.available(); // listen for incoming clients
if (client) { // if you get a client,
Serial.println("new client"); // print a message out the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println();
// the content of the HTTP response follows the header:
client.print("<style>");
client.print(".container {margin: 0 auto; text-align: center; margin-top: 100px;}");
client.print("button {color: white; width: 100px; height: 100px;");
client.print("border-radius: 50%; margin: 20px; border: none; font-size: 20px; outline: none; transition: all 0.2s;}");
client.print(".red{background-color: rgb(196, 39, 39);}");
client.print(".green{background-color: rgb(39, 121, 39);}");
client.print(".blue {background-color: rgb(5, 87, 180);}");
client.print(".off{background-color: grey;}");
client.print("button:hover{cursor: pointer; opacity: 0.7;}");
client.print("</style>");
client.print("<div class='container'>");
client.print("<button class='red' type='submit' onmousedown='location.href=\"/RH\"'>ON</button>");
client.print("<button class='off' type='submit' onmousedown='location.href=\"/RL\"'>OFF</button><br>");
client.print("<button class='green' type='submit' onmousedown='location.href=\"/GH\"'>ON</button>");
client.print("<button class='off' type='submit' onmousedown='location.href=\"/GL\"'>OFF</button><br>");
client.print("<button class='blue' type='submit' onmousedown='location.href=\"/BH\"'>ON</button>");
client.print("<button class='off' type='submit' onmousedown='location.href=\"/BL\"'>OFF</button>");
client.print("</div>");
// The HTTP response ends with another blank line:
client.println();
// break out of the while loop:
break;
} else { // if you got a newline, then clear currentLine:
currentLine = "";
}
} else if (c != '\r') { // if you got anything else but a carriage return character,
currentLine += c; // add it to the end of the currentLine
}
// Check to see if the client request was /X
if (currentLine.endsWith("GET /RH")) {
digitalWrite(LEDR, HIGH);
}
if (currentLine.endsWith("GET /RL")) {
digitalWrite(LEDR, LOW);
}
if (currentLine.endsWith("GET /GH")) {
digitalWrite(LEDG, HIGH);
}
if (currentLine.endsWith("GET /GL")) {
digitalWrite(LEDG, LOW);
}
if (currentLine.endsWith("GET /BH")) {
digitalWrite(LEDB, HIGH);
}
if (currentLine.endsWith("GET /BL")) {
digitalWrite(LEDB, LOW);
}
}
}
// close the connection:
client.stop();
Serial.println("client disconnected");
}
}
void printWiFiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print where to go in a browser:
Serial.print("To see this page in action, open a browser to http://");
Serial.println(ip);

didn't you see the WiFiWebServer example of the WiFiNINA library
