Hi Guys, some time ago I realized a thermostat for my gas boiler, to interface the boiler I used an original Arduino MKR1000 with a webserver inside, in order to manage http requests to switch on and switch off the boiler.
The project is working fine except that each three or four days I need to go downstairs,
turn arduino off and turn it on again because it goes to a standstill.
During this standstill:
- the green led, the one that indicates that arduino is connected to a power supply, is on, and another orange blinking led, next to the green one, turns on.
- If I try to ping the arduino IP address, it works fine
- If I try to submit an http request via browser to arduino webserver then no response comes back
I have no idea if it could be an hardware or software issue, anyway this is sketch:
#include <WiFi101.h>
#include <WiFiClient.h>
#include <WiFiServer.h>
#include <WiFiSSLClient.h>
#include <WiFiUdp.h>
#include <SPI.h>
const char* ssid = "*****";
const char* pass = "*****";
const char* host = "192.168.1.10";
int keyIndex = 0;
int relaypin = 2;
int currentState = 0;
bool val = true;
int status = WL_IDLE_STATUS;
WiFiServer server(301);
void setup() {
Serial.begin(9600); // initialize serial communication
Serial.print("Start Serial ");
pinMode(relaypin, OUTPUT);
digitalWrite(relaypin, LOW);
// Check for the presence of the shield
Serial.print("WiFi101 shield: ");
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("NOT PRESENT");
return; // don't continue
}
Serial.println("DETECTED");
// 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(10000);
}
server.begin(); // start the web server on port 301
printWifiStatus(); // you're connected now, so print out the status
}
void loop() {
WiFiClient 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();
// the content of the HTTP response follows the header:
client.print("PIN " + (String)relaypin + " IS " + (String)digitalRead(relaypin));
// 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 /ON" or "GET /OFF":
if (currentLine.endsWith("GET /ON")) {
digitalWrite(relaypin, HIGH);
}
if (currentLine.endsWith("GET /OFF")) {
digitalWrite(relaypin, LOW);
}
}
}
// 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");
}
Somebody could help?
