This is my original code:
- CODE: SELECT_ALL_CODE
#include <CytronWiFiShield.h>
#include <CytronWiFiServer.h>
#include <SoftwareSerial.h>
#define WiFi wifi
char ssid[] = "XXX"; // your network SSID (name)
char pass[] = "XXX"; // your network password
int keyIndex = 0; // your network key Index number (needed only for WEP)
ESP8266Server server(80);
bool status = false;
int i;
const int button[2] = {5,6};
int thisPin;
int val[2];
int out;
void setup() {
for (int thisPin = 0; thisPin < 2; thisPin++) {
pinMode(button[thisPin], INPUT);
}
Serial.begin(9600); // initialize serial communication
// check for the presence of the shield:
if (!WiFi.begin(2, 3)) {
Serial.println("WiFi shield not present");
while (true); // don't continue
}
String fv = WiFi.firmwareVersion();
Serial.println(fv);
// attempt to connect to Wifi network:
while (!status) {
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.connectAP(ssid, pass);
}
server.begin(); // start the web server on port 80
printWifiStatus(); // you're connected now, so print out the status
}
void loop() {
ESP8266Client client = server.available(); // listen for incoming clients
if(!client) return;
Serial.println("new client");
if (client.connected()) //if client is present and connected
{
String s = client.readStringUntil('\r'); //get the first line of request
// Check to see if the client request was "GET /H" or "GET /L":
for (int i=0;i<2;i++){
val[i]=digitalRead(button[i]);
}
Serial.print(s);
while(client.available())
Serial.write(client.read()); // print the client request out the serial monitor
// 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("<TITLE>Read Sensor</TITLE>");
// client.println("<center>");
// client.println("</HEAD>");
// client.println("<BODY>");
// client.println("<H1>Sensor Reading</H1>");
// client.println("<hr />");
// client.println("<br />");
// the content of the HTTP response follows the header:
// for (int button = 0; button < 2; button++) {
// client.print("Station ");
// client.print(button + 1);
// client.print(" : ");
// client.print(val[button]);
// client.println("<br />");
// }
client.println("0000");
// The HTTP response ends with another blank line:
//client.println();
//delay(10);
// close the connection:
client.stop();
Serial.println("client disonnected");
}
}
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");
// print where to go in a browser:
Serial.print("To see this page in action, open a browser to http://");
Serial.println(ip);
}
It works well i would like to make my Arduino as a client so i modified my code into the code below:
- CODE: SELECT_ALL_CODE
#include <CytronWiFiShield.h>
#include <CytronWiFiServer.h>
#include <CytronWiFiClient.h>
#include <SoftwareSerial.h>
#define WiFi wifi
char ssid[] = "XXX"; // your network SSID (name)
char pass[] = "XXX"; // your network password
int keyIndex = 0; // your network key Index number (needed only for WEP)
ESP8266Client client(80);
bool status = false;
int i;
const int button[2] = {5,6};
int thisPin;
int val[2];
int out;
void setup() {
for (int thisPin = 0; thisPin < 2; thisPin++) {
pinMode(button[thisPin], INPUT);
}
Serial.begin(9600); // initialize serial communication
// check for the presence of the shield:
if (!WiFi.begin(2, 3)) {
Serial.println("WiFi shield not present");
while (true); // don't continue
}
String fv = WiFi.firmwareVersion();
Serial.println(fv);
// attempt to connect to Wifi network:
while (!status) {
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.connectAP(ssid, pass);
}
client.begin(); // start the web server on port 80
printWifiStatus(); // you're connected now, so print out the status
}
void loop() {
ESP8266Server server = client.available(); // listen for incoming clients
if(!server) return;
Serial.println("new server");
if (server.connected()) //if client is present and connected
{
String s = server.readStringUntil('\r'); //get the first line of request
// Check to see if the client request was "GET /H" or "GET /L":
for (int i=0;i<2;i++){
val[i]=digitalRead(button[i]);
}
Serial.print(s);
while(server.available())
Serial.write(server.read()); // print the client request out the serial monitor
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)

// client.print(val[button]);
// client.println("<br />");
// }
server.println("0000");
// The HTTP response ends with another blank line:
//client.println();
//delay(10);
// close the connection:
server.stop();
Serial.println("client disonnected");
}
}
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");
// print where to go in a browser:
Serial.print("To see this page in action, open a browser to http://");
Serial.println(ip);
}
This code cannot be compiled and i got an error message 'class ESP8266Client' has no member named 'begin'.
Can anyone please help?
