ESP8266 Community Forum

Hi, on PIN GIO2 of ESP 8266 01 I connect a DHT temperature sensor. Booting the esp 8266 is very difficult. Sometimes the first attempt is successful but many times I must try many times ? Any ideas or hints ?

Always make sure your schematics (ie. pull-up/pull-down resistors) are in order and your projects will perform as intended.

Although i connected RST with 10 k ohm to vcc ( chpd to vcc )
sometimes boot is succesful.
