Hello I need help with sending data from Arduino to MIT APP iNVENTOR using WiFi. This is my program in arduino:
#include <SPI.h>
#include <WiFiNINA.h>
char ssid = "Marolt"; // your network SSID (name)
char pass = "marolt99"; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS;
WiFiServer server(80);
String readString;
int grijac = 2;
int pumpa = 3;
int LED = 4;
int RV100 = 5;
int RV60 = 6;
int RV30 = 7;
int RV5 = 12;
int lux = 13;
int temp = A0;
int Vo;
float R1 = 10000;
float logR2, R2, T, Tc, Tf;
float c1 = 1.123768547e-03, c2 = 2.357000486e-04, c3 = 0.7576833803e-07;
String razinavode100 = "0";
float xtemp = 0.0;
void setup() {
Serial.begin(9600);
while(status != WL_CONNECTED){
Serial.print("Pokušavam se spojiti na Wifi koji se zove: ");
Serial.println(ssid);
status = WiFi.begin(ssid, pass);
delay(10000);
}
server.begin();
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
IPAddress ip = WiFi.localIP();
Serial.print("IP adresa: ");
Serial.println(ip);
pinMode(grijac, OUTPUT);
pinMode(pumpa, OUTPUT);
pinMode(LED, OUTPUT);
pinMode(RV100, OUTPUT);
pinMode(RV60, INPUT);
pinMode(RV30, INPUT);
pinMode(RV5, INPUT);
pinMode(lux, INPUT);
pinMode(temp, INPUT);
// put your setup code here, to run once:
}
void loop() {
WiFiClient client = server.available();
if (!client){
return;
}
Serial.println("New client connected");
while(!client.available()){
delay(1);
}
String request = client.readStringUntil('\r');
Serial.println(request);
if (request.indexOf("/SensorReading") != -1){
Serial.println("sending data");
digitalWrite(RV100, LOW);
razinavode100 = String((digitalRead(RV100)));
delay(10);
}
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // Important.
client.println(razinavode100);
Serial.print("Client disconnected: ");
Serial.println(client.remoteIP());
client.flush();
delay(10);
I did the sam thing as I saw on some videos and I still can't get data on my phone. Arduino is getting data from aplication and it wants to send it but I can't read it in my aplication. PLESAE HELP ME, sorry for bad english.
