Nodemcu get stuck when using MQTT and dsleep
Posted: Tue Mar 01, 2016 3:39 amHello gentlemen,
What am I doing wrong? See following lua code. It works, but only for few minutes. I tested various firmware versions also various branches, but results are approximately the same. Nodemcu hangs after few minutes. It should work as an external thermometer but becouse of stability it is unusable.
file: main.lua
file: init.lua
And this is the output from serial console (my latest attempt,it is not so much helpful):

local temperature = string.format("%d.%03d", math.floor(temp), temp_dec)
local humidity = string.format("%d.%03d", math.floor(humi), humi_dec)
local a = {}
a["temperature"] = temperature;
a["humidity"] = humidity;
