ESP8266 E-12 (Kinda ARDUINO) Firmware weird thing!

Using Arduino IDE 1.x

Hey my ESP8266 open another boot thing if 3v and gnd are connected. Is there any other possible ways to avoid this without plug out the pins?

Thanks!

Please give a clear explanation of what is happening. I have no idea what you re asking.

"Open another boot thing" means nothing.

Okey what I am asking for is that the firmware of ESP8266 tries to boot from my SDCard because its connected. And to get the normal boot(runs the arduino code) I need to unplug and plug it in again the sd card. So im asking how can I disable that bootmode when it tries to boot from the sd card? Thanks!

Normal boot: GPIO 0 HIGH, GPIO 2 HIGH.
Flash boot: GPIO 0 LOW, GPIO 2 - subject to much debate - for most people doesn't seem to matter - prefered HIGH.
SD card boot: GPIO 0 HIGH, GPIO 2 LOW.

In SD card boot the serial will display the communication between the ESP and the SD card - which you don't have - so it's just a 'hello where are you' from the ESP that it keeps sending in an ever more sorry tone as time goes on, but it never gives up hope, serial can't detect tone so you don't see it.
So please, ensure GPIO 2 is HIGH at boot or reset and don't distress the poor thing.
Hope that helps.

Okey.. I understood nothing there but I came up with another idea how to do that thing.

It seems you control the way it boots by applying the correct levels to GPIO 0 and GPIO 2,
is that hard to understand?
