ESP8266 Community Forum

Got the vibration detection board working with MQTT. This was really an ordeal given that the memory issues with LUA and the ESP8266 are really frustrating. Its trial and error. Finally and after stripping the code to the bare minimum, i.e., remove all the fancy web page interface to the board configuration, things got working pretty good.

I installed my own MQTT broker on a MacBook, Mosquitto, and got it to work without major issues.

MQTT is really great for IoT, of course if you have a broker running or want to go through a public broker, otherwise my ad-hoc messaging solution I think it is a bit easier for home projects. But again, MQTT is the way to go if you want to control several devices, send and receive various commands, etc.
On my future boards I will offer ad-hoc messaging or MQTT check http://www.horaciobouzas.com

Hi Thakshak,

I think Hbouzas is referring to the ram not the flash.

I had some ram issue when trying to post to thingspeak with lua...

Plucker

Try to compile the script before run, an then run script.lc instead script.lua
