/*
Xively sensor client with Strings
This sketch connects an analog sensor to Xively,
using an Arduino Yún.
created 15 March 2010
updated 27 May 2013

*/
// include all Libraries needed:
#include <Process.h>
#include "passwords.h" // contains my passwords, see below
/*
NOTE: passwords.h is not included with this repo because it contains my passwords.
You need to create it for your own version of this application. To do so, make
a new tab in Arduino, call it passwords.h, and include the following variables and constants:
#define APIKEY "foo" // replace your pachube api key here
#define FEEDID 0000 // replace your feed ID
#define USERAGENT "my-project" // user agent is the project name
*/
// set up net client info:
const unsigned long postingInterval = 60000; //delay between updates to xively.com
unsigned long lastRequest = 0; // when you last made a request
String dataString = "";
void setup() {
// start serial port:
Bridge.begin();
Console.begin();
while(!Console); // wait for Network Console to open
Console.println("Xively client");
// Do a first update immediately
updateData();
sendData();
lastRequest = millis();
}

// get a timestamp so you can calculate reading and sending intervals:

// if the sending interval has passed since your
// last connection, then connect again and send data:

dataString = "Temperature,";

// this method makes a HTTP connection to the server:

// form the string for the API header parameter:
String apiString = "X-ApiKey: ";
apiString += APIKEY;
// form the string for the URL parameter:
String url = "https://api.xively.com/v2/feeds/";
url += FEEDID;
url += ".csv";
// Send the HTTP PUT request
// Is better to declare the Process here, so when the
// sendData function finishes the resources are immediately
// released. Declaring it global works too, BTW.
