Hi,
I know this has been discussed many times, but I cannot see why this particular script doesn't run unless the Serial Monitor is open.
I'm trying to log temperature sensor data to emoncms.org, using a LinkIt One, over Wifi. This works fine when it's connected to my PC, and the Serial Monitor is open in Arcuino IDE. But as soon as I close the serial monitor, or let it run off a battery, the logging stops.
Here's the full sketch:
#include <LTask.h>
#include <LWiFi.h>
#include <LWiFiClient.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include<LBattery.h>
OneWire ds(8); // on pin 8 (a 4.7K resistor is necessary)
DallasTemperature sensors(&ds); // Pass our oneWire reference to Dallas Temperature.
#define WIFI_AP "xxxxxxxxxxxx"
#define WIFI_PASSWORD "xxxxxxxxxxxx"
#define WIFI_AUTH LWIFI_WPA // choose from LWIFI_OPEN, LWIFI_WPA, or LWIFI_WEP according to your WiFi AP configuration
LWiFiClient client;
// emoncms Settings
char* server = "emoncms.org";
String writeAPIKey = "xxxxxxxxxxxx";
int node = 1; //if 0, not used
int sent = 0;
int myPeriodic = 30;
DeviceAddress Room1Temp = { 0x28, 0xBA, 0xB6, 0x65, 0x05, 0x00, 0x00, 0x21 };
DeviceAddress Room1RoofTemp = { 0x28, 0x52, 0xCA, 0xA0, 0x07, 0x00, 0x00, 0x12 };
DeviceAddress Room2Temp = { 0x28, 0x1D, 0xB3, 0xE6, 0x05, 0x00, 0x00, 0x7B }; // Silver probe
DeviceAddress Room2RoofTemp = { 0x28, 0x92, 0xDC, 0x98, 0x05, 0x00, 0x00, 0x76 }; // Black probe

DeviceAddress OutsideTemp = {0x28, 0x50, 0x00, 0xA0, 0x07, 0x00, 0x00, 0xE3 };
DeviceAddress PatioTemp = {0x28, 0x50, 0x00, 0xA0, 0x07, 0x00, 0x00, 0xE3 };
