Hi,
I found a code for a web client and when I load this program to my arduino and esp8266 don’t get a reply from the website from my get request.
This is my code:
/*
WiFiEsp example: WebClient
This sketch connects to google website using an ESP8266 module to
perform a simple web search.
For more details see: http://yaab-arduino.blogspot.com/p/wifiesp-example-client.html
*/
#include "WiFiEsp.h"
// Emulate Serial1 on pins 8/9 if not present
#ifndef HAVE_HWSERIAL1
#include "SoftwareSerial.h"
SoftwareSerial Serial1(8, 9); // RX, TX
#endif
char ssid[] = "waterfill"; // your network SSID (name)
char pass[] = "waterfill08"; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio's status
char server[] = "api.pushingbox.com";
// Initialize the Ethernet client object
WiFiEspClient client;
void setup()
{
// initialize serial for debugging
Serial.begin(115200);
// 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();
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 /pushingbox?devid=v0DC35307E3AE991");
client.print("&a=");
client.print(String(20));
client.print("&b=");
client.print(String(10));
client.println(" HTTP/1.1");
client.println("Host: api.pushingbox.com");
client.println();
}
}
void loop()
{
// if there are incoming bytes available
// from the server, read them and print them
while (client.available()) {
char c = client.read();
Serial.write(c);
}
// 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 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");
}
I use that code then cannot send my data to pushingbox
in serial monitor show up like this
