It works, thanks!

Hi, lajolo

I changed your code for my use in the following way. But failed many times to send GET request. I can see that esp8266 connected wifi. BTW - not a module or home network issue. I've ran some piece of code doing the same stuff but using httpd. So from your experience, can you help out of this strange problem? Merci beaucoup.

the changed code is here:

// Import required libraries
#include <ESP8266WiFi.h>

// WiFi parameters
const char* ssid = "TorahYongquan";
const char* password = "PlantoWang";

// Host
const char* host = "planto.oicp.net";

void setup() {
// Start Serial
Serial.begin(115200);
delay(10);

// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}

int value = 0;

void loop() {

Serial.print("Connecting to ");
Serial.println(host);

// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 80;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}

// This will send the request to the server
client.print(String("GET /add.php?temper=22") + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
delay(10);

Serial.print("client.status(): ");
Serial.println(client.status());
Serial.print("client.available(): ");
Serial.println(client.available());
Serial.print("client.connected(): ");
Serial.println(client.connected());

// Read all the lines of the reply from server and print them to Serial
while(client.available()){
String line = client.readStringUntil('\r\n');
Serial.print(line);
}

Serial.println();
Serial.println("closing connection");
delay(5000);

}

And I have left '\r' here:

while(client.available()){
String line = client.readStringUntil('\r');
Serial.print(line);
}

Hello,

in your code you want to access the website:
http://planto.oicp.net/add.php?temper=22

From my browser I cannot access it.

Are you sure that the address is correct?

Can you access it from your browser?
