Product OTA handler

Gotcha. So is this kinda what you are thinking?

bool updateOccuring = false;

//AFTER WE GRAB SENSOR DATA, CONNECT, AND PUBLISH
   if (updateOccuring){
        downloadUpdate();
   }

void otaHandler () {
    Serial.println("Update is pending. Will reboot after update.");
    updateOccuring = true;
}

void downloadUpdate(){
    Particle.publish("Updating pending.", "True", 60, PRIVATE); //for troubleshooting
    loop_count = 0;
    while (loop_count < 600) {
      Particle.process();
      delay(100);
      loop_count++;
    }
}
