Can the 12e onboard LED be controlled?

Hi! I've been trying to figure out if the esp-12e's LED can be controlled separately from its function as a UART communication indicator light. Right now, when I upload a program or communicate with the serial console, a small blue LED flashes on the 12e. Is it possible to control this LED separately? I've tried all of the GPIOs and can't seem to get it to work. Thanks!

The LED is directly connected to the UART TX line. You can use the TX pin as GPIO1 to control the LED, but only if you don't use UART.

I also have a problem with using the onboard LED on my ESP-12E module.
It does not work with GPIO1 (It works fine with other modules, including ESP-12, but not ESP-12E).
Update:
My ESP-12E has onboard led connected to GPIO2 thru internal 470 Ohm resistor.

Just for the record: GPIO1 worked for me; however, I also discovered that some of my cheaper ESP-12E chips' LEDs are blown (not working) right out of the box.
