Hello
I would like to control arduino MKR WiFi 1010 through a smart phone using MIT app Inventor. My arduino will be connected at home to my home network. My smart phone will be connected to my office network. How I can transfer data for arduino control? Help please!
Here is my code for arduino:
#include <SPI.h> //What is used to communicate witht he WiFi chip
#include <WiFi101.h> //Wifi library fro Arduino MKR1000 and WiFi shield
int lControl = 6; //Digital pin that LED is connected to on the MKR1000
char ssid[] = "YourNetwork"; // your network SSID (name)
char pass[] = "YourPassword"; // your network password
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS; //status of wifi
WiFiServer server(80); //declare server object and spedify port, 80 is port used for internet
void setup() {
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
while (true);
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
// 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();
}
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();
client.print("Value at A0 is ");
client.print(analogRead(A0));
client.print("<br>");
// 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 /H" or "GET /L":
if (currentLine.endsWith("GET /H")) {
digitalWrite(lControl, HIGH); // GET /H turns the LED on
}
if (currentLine.endsWith("GET /L")) {
digitalWrite(lControl, LOW); // GET /L turns the LED off
}
}
}
// close the connection:
client.stop();
}
}
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");
