Using Spark.Disconnect() & being able to flash over-the-air?

Ok, this is fun… will disconnect you from the Cloud on start up, and then if you need to reflash your code just press the Mode button to reconnect to the Cloud first. It also ignores the Mode button for the first 3 seconds after start up, so you have enough time to get your Core into Smart Config if you need it.

uint32_t startTime = 0;
void setup() {
    startTime = millis(); // capture the time that our app starts
    Spark.disconnect();
}

void loop() {
    if(ModeBtnPressed()) {
        RGB.control(true);
        for(uint8_t x=0; x<2; x++) { // Ready the Hyperdrive!
            RGB.color(255,0,0); //red
            delay(100);
            RGB.color(255,100,0); //orange
            delay(100);
            RGB.color(255,255,0); //yellow
            delay(100);
            RGB.color(0,255,0); //green
            delay(100);
            RGB.color(0,255,255); //cyan
            delay(100);
            RGB.color(0,0,255); //blue
            delay(100);
            RGB.color(255,0,255); //magenta
            delay(100);
            RGB.color(255,255,255); //white
            delay(100);
        }
        RGB.control(false);
        Spark.connect(); // Engage Hyperdrive!
    }
}

bool ModeBtnPressed() {
    if(millis() - startTime > 3000) { // wait at least 3s for smart config
        if(BUTTON_GetDebouncedTime(BUTTON1) >= 100) {
            BUTTON_ResetDebouncedState(BUTTON1);
            return 1;
        }
    }
    return 0;
}
