esp8266 door/window sensor modemcu without arduino

No, now doesn't power on. Led is off. I've built a little interface for testing purpose with all gpios cabled and i suppose that some gpio get in touch because i've seen some smoke... Or pheraps i've connected gpio15 to gnd and then make a mistake in software pulled up gpio15.... )

Now all gpio cable are fixed in a little breadboard... and i'm waiting for new modules to restart....

Done using another gpio on esp-12... It works but... UNSTABLE... always the same
