Hello together,
I know that somebody maybe try to solve it. I have problem with my nodemcu. My app in Arduino IDE reads data from DHT22, BMP180 and all data sense to google spreadsheet. Then it reads settings from this spreadsheet and set DO. Then it goes sleep for 1200 s, then it is young again. It works great, but randomly nodemcu freeze /hangs and i don’t know why. I try several tipy with wtdog, but without success. Some time freeze after 6 days, some time 6 hours. If somebody has some tips send it to me, I can share you a source code for revision. After 3 months I am not able to solve it. Thanks. Sorry for my english.
