#65138 i am using WiFiEsp library to connect to the Internet with an Arduino board. I want to make a http get request to server per second, but the whole code run about 2 to 3 second. Is there any way to speed up the code? I just want to upload some sensor data to mysql.

Code: Select all#include "WiFiEsp.h"

// Emulate Serial1 on pins 6/7 if not present
#ifndef HAVE_HWSERIAL1
#include "SoftwareSerial.h"
SoftwareSerial Serial1(3, 4); // RX, TX
#endif

char ssid[] = "testing";            // your network SSID (name)
char pass[] = "123456";        // your network password
int status = WL_IDLE_STATUS;     // the Wifi radio's status

char server[] = "temmonitor.pe.hu";

// Initialize the Ethernet client object
WiFiEspClient client;

void setup()
{
  // initialize serial for debugging
  Serial.begin(9600);
  // initialize serial for ESP module
  Serial1.begin(9600);
  // initialize ESP module
  WiFi.init(&Serial1);

  // check for the presence of the shield
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // don't continue
    while (true);
  }

  // attempt to connect to WiFi network
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to WPA SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network
    status = WiFi.begin(ssid, pass);
  }

  // you're connected now, so print out the data
  Serial.println("You're connected to the network");
 
  printWifiStatus();

  Serial.println();
}

void loop()
{
    unsigned long starttime, stoptime, looptime;
  starttime = millis();
  senddata();
   stoptime = millis();
  looptime = stoptime - starttime;
  Serial.print("Run time :");
  Serial.println(looptime);
  // if there are incoming bytes available
  // from the server, read them and print them
  while (client.available() ) {
//    char c = client.read();
//    Serial.write(c);
   client.stop();
  }

//  // if the server's disconnected, stop the client
//  if (!client.connected()) {
//    Serial.println();
//    Serial.println("Disconnecting from server...");
//
//    client.stop();
//
//    // do nothing forevermore
//    while (true);
//  }
}

void senddata(){
   Serial.println("Starting connection to server...");
  // if you get a connection, report back via serial
  if (client.connect(server, 80)) {
    Serial.println("Connected to server");
    // Make a HTTP request
    client.println("GET /upload.php?vid=44 HTTP/1.1");
    client.println("Host: temmonitor.pe.hu");
    client.println("Connection: close");
    client.println();
  }
  }

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 the received signal strength
  long rssi = WiFi.RSSI();
  Serial.print("Signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
