Hi,
I need you help, I'm trying to send data from an analog sensor, GSM to Xively webserver.
Below the code I am using and the errors:
#include
#include
SoftwareSerial mySerial(2, 3);
void setup()
{
mySerial.begin(19200); // the GPRS baud rate
Serial.begin(19200); // the GPRS baud rate
delay(500);
}
void loop()
{
//after start up the program, you can using terminal to connect the serial of gprs shield,
//if you input 't' in the terminal, the program will execute SendTextMessage(), it will show how to send a sms message,
//if input 'd' in the terminal, it will execute DialVoiceCall(), etc.
if (Serial.available())
switch(Serial.read())
{
case 's':
Send2Pachube();
break;
}
if (mySerial.available())
Serial.write(mySerial.read());
}
///send2Pachube()///
///this function is to send the sensor data to the pachube, you can see the new value in the pachube after execute this function///
void Send2Pachube()
{
mySerial.println("AT+CGATT?");
delay(1000);
ShowSerialData();
mySerial.println("AT+CSTT=\"net2.vodafone.pt\"");//start task and setting the APN,
delay(1000);
ShowSerialData();
mySerial.println("AT+CIICR");//bring up wireless connection
delay(3000);
ShowSerialData();
mySerial.println("AT+CIFSR");//get local IP adress
delay(2000);
ShowSerialData();
mySerial.println("AT+CIPSPRT=0");
delay(3000);
ShowSerialData();
mySerial.println("AT+CIPSTART=\"tcp\",\"api.pachube.com\",\"8081\"");//start up the connection
delay(2000);
ShowSerialData();
mySerial.println("AT+CIPSEND");//begin send data to remote server
delay(4000);
ShowSerialData();
String humidity = "1031";//these 4 line code are imitate the real sensor data, because the demo did't add other sensor, so using 4 string variable to replace.
String moisture = "1242";//you can replace these four variable to the real sensor data in your project
mySerial.print("{\"method\": \"put\",\"resource\": \"/feeds/703024837/\",\"params\"");//here is the feed you apply from pachube
delay(500);
ShowSerialData();
mySerial.print(": {},\"headers\": {\"X-PachubeApiKey\":");//in here, you should replace your pachubeapikey
delay(500);
ShowSerialData();
mySerial.print(" \"mDbE0acjjkSqks6wQXBoxWKyE0XPrBR03h1rNfbQMpTOW1jR\"},\"body\":");
delay(500);
ShowSerialData();
mySerial.print(" {\"version\": \"1.0.0\",\"datastreams\": ");
delay(500);
ShowSerialData();
mySerial.println("[{\"id\": \"sensor1\",\"current_value\": \"" + moisture + "\"},");
delay(500);
ShowSerialData();
mySerial.println("{\"id\": \"sensor2\",\"current_value\": \"" + humidity +"\"}]},\"token\": \"lee\"}");
delay(500);
ShowSerialData();
mySerial.println((char)26);//sending
delay(5000);//waitting for reply, important! the time is base on the condition of internet
mySerial.println();
ShowSerialData();
mySerial.println("AT+CIPCLOSE");//close the connection
delay(100);
ShowSerialData();
}
void ShowSerialData()
{
while(mySerial.available()!=0)
Serial.write(mySerial.read());
}
