I have Flashed ESP8266 NodeMcu v0.9 5/12/2014 and this works great with MQTT.
I have two questions:
1. Where do I connect with couple of Battery? Where is 5V IN ?
2. I read somewhere that upoading init.lua is painfull if you need to upload it again if something is not programmed so good and have to be FLASHED again if you need to put new init file. Is this correct? Can init.lua be easy ploaded and replaced? I have test.lua for now but I'd like to put init.lua.
Thanx in advance,
Faramon
