Posted: Tue Feb 17, 2015 3:27 amI had the same problem. The problem is that, if loaded after boot through init.lua, the process is too fast and the chip is not connected to wifi when the script tries to publish or subscribe.
I fixed it by delaying the dofile in init.lua until the wifi.sta.status is 5. This is what my init.lua looks like and it works quite well.
Hope this works for you....

Code: Select all
if wifi.sta.status() ~= 5 then tmr.alarm(6, 10000,0, function(d) dofile('init.lua') end) return end
if wifi.sta.status() == 5 then dofile('mqtt.lua') return end
Hope this works for you....

I'm just trying to connect manually by sending commands in a terminal. It all works fine with 20150127:
Code: Select all
NodeMCU 0.9.5 build 20150127 powered by Lua 5.1.4
lua: cannot open init.lua
> print(wifi.sta.getip())
192.168.0.47 255.255.255.0 192.168.0.1
> m = mqtt.Client('garage_sens', 120) --, "user", "password")
> m:connect("192.168.1.100", 1883, 0, function(conn) print("connected") end)
> connected
Then I flash 20150212 and try again:
Code: Select all
NodeMCU 0.9.5 build 20150212 powered by Lua 5.1.4
lua: cannot open init.lua
> print(wifi.sta.getip())
192.168.0.47 255.255.255.0 192.168.0.1
> m = mqtt.Client('garage_sens', 120) --, "user", "password")
> m:connect("192.168.1.100", 1883, 0, function(conn) print("connected") end)
> It never returns "connected."
