Everytime, as the ESP8266 12-E boots up, the LED flashes once.
I would like to reduce the power consumption, during this proces.

the ESP communicates at a baud of 74880 and says:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x4010f000, len 1264, room 16
tail 0
chksum 0x42
csum 0x42
~ld

could we disable this output?
If its not possible, is there a way to cut off the LED from TX line ?
The last time I have tried this, the ESP 12-E was dead.

It is just a minuscule amount of power ... certainly nothing compared to the RF section of the ESP8266.

If the light bothers you, put black fingernail polish over the LED.
