3.Dweeting sensor values

Dweeting sensor values on dweet.io

     This is  also HTTP communication between launchpad and cloud server dweet.io. Dweet.io is simple publishing and subscribing for machines, sensors, devices, robots, and gadgets (we just call them things). We call published messages ‘dweets’. It’s helpful to think of dweet.io as a Twitter for things, in fact. We have to specify a thing name that must unique. Another advantage of this is for dweet operation we don’t want to sign up for an account. In this the sensor data are sending as datasources .

sample Energia code

//#include <SPI.h>

#ifndef __CC3200R1M1RGC__

#endif

#include <WiFi.h>

// your network name also called SSID

char ssid[] = "**********";

// your network password

char password[] = "***********";

int status = WL_IDLE_STATUS;

IPAddress server(54,88,231,110);  // dweet

// Initialize the client library

// Dweet parameters

#define thing_name  "**********"

int sample2=0;

 // attempt to connect to Wifi network:

  Serial.print("Attempting to connect to Network named: ");

  // print the network name (SSID);

  Serial.println(ssid); 

  // Connect to WPA/WPA2 network. Change this line if using open or WEP network:

  WiFi.begin(ssid, password);

  while ( WiFi.status() != WL_CONNECTED) {

    // print dots while we wait to connect

    // if you get a connection, report back via serial:
