ESP8266 Community Forum

- Tue Dec 20, 2016 3:56 pm #59758 Hi guys,

quick question. Is it possible to hard-reset the esp8266 using one of its own gpios? I'm using a fingerprint sensor in my project, and somehow it's messing up communication with Phillips Hue lights. The sketch 'knows' when the this event happens. So it possible to, for example, tie gpio0 to the reset pin and then write a low signal when such an event happens? I'm using the Wemos d1 mini board btw.

thank you in advance!

kind regards,
Bas
