#24206 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!

#26154 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.
