This section seems to be a better place for my problem..
I want to be able to access the arduino from ip/get_variables
and based on those variables to send a response to another page.
So it must be a client and a server.
Here's my code.
The problem seems to be the sendGET function, because the program halts (it won't respond when i access it from the browser) after it executes.
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "PinkLink"; // your network SSID (name)
char pass[] = "unu1doi2trei3"; // your network password
int status = WL_IDLE_STATUS;
WiFiServer server(80);
WiFiClient client;
char serverName[] = "puiucristian.com";
void setup() {
Serial.begin(115200); // initialize serial communication
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
while(true); // don't continue
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to Network named: ");
Serial.println(ssid); // print the network name (SSID);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
delay(5000);
}
server.begin(); // start the web server on port 80
//printWifiStatus(); // you're connected now, so print out the status
Serial.println("Ready");
}
int x = 0; // if it's 1, it will trigger the sendget function
void loop() {
x = 0; // is 1 only if there's a get variable named .....
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();
client.println("..");
// 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 "GET /H" or "GET /L":
if (currentLine.endsWith("GET /doSomething")) {
x = 1;
}
}
}
// close the connection:
client.stop();
Serial.println("client disonnected");
}
//check if x is 1
if (x == 1) sendGET();
}
void sendGET() {
if (client.connect(serverName, 80)) {
Serial.println("connected");
client.println("GET /bu.php HTTP/1.0");
client.println();
}
else {
Serial.println("connection failed");
Serial.println();
}
while(client.connected() && !client.available()) delay(1); //waits for data
while (client.connected() || client.available()) { //connected or data available
char c = client.read();
Serial.print(c);
}
Serial.println();
Serial.println("disconnecting.");
Serial.println("==================");
Serial.println();
client.stop();
}
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);
