Re: ESP12E onboard blue LED

Hi that does not tie in with the behaviour i see. Its been reverse engineered by someone (not official)
What is strange is that the official documents schematic from AI thinker for the esp12e and esp12f do not show an led at all!
My feeling is that the blue led shows wifi transmits amongst other things and i dont see why it should be connected to GPIO2. Some folks say it shows the TX1 debug log outputs . ive done a system_set_os_print(off) and the onboard blue led still flashes.
