ESP8266 Community Forum

- Mon Jan 04, 2016 4:44 pm #37909 I've got couple of ESP8266 -01 version (cheapest ones form Aliexpress) - it's the one with two GPIOs. Running 0.9.6-dev latest, but having issues with decimial readaing below zero using DHT22 library - I decided to update to integer build from http://nodemcu-build.com/. All I do is add DHT22 to default settings, buid - either dev or master - but after flashing with esptool.py the script fails right after 100%, and the ESP unit is in crash-loop. I can still go back to original 0.9.6dev NodeMCU flash but - why is it crashing ?

I have the same issue with a ESP-01 black...

Thanks!
