Issues with onboard blue led on esp8266-01

Using some of my development boards, i blink the onboard led in a slow blink, one second on, one second off. When I run this code on a esp8266-01 the little blue led seems to just flicker, won't stay on. I am using the LED_BUILTIN and setting HIGH for off, and LOW for on. What am I missing? Thanks.

I know exactly wat your problem is.
You are forgetting to include your code and a schematic (and/or pictures).
Sorry mate, but we can't help you without a proper description of the problem (and as much as possible other relevant information) .

esp-01 modules come in different layouts.
the newer ones don't have a red led and the blue one is on a different gpio.
so QuickFixs comment holds true ...

Thanks for the responses, my code is very simple. I have a timer running at a frequency higher than the blink I want, so I count timer ticks and only action when it exceeds my blink threshold.
Code: Select all blinkCount++;
if(blinkCount>blinkDelay)
{
if(isOn)
{
digitalWrite(LED_BUILTIN,HIGH);
}
else
{
digitalWrite(LED_BUILTIN,LOW);
}
isOn=!isOn;
blinkCount=0;
} Here is an image of my production setup, I did just order a few of the new boards without a power led.
