How to use android app to control LM

[Alexander]

You can use a WebSocket connection to read/write object values. There are built-in JavaScript libraries in LM that can be used in your app if using Cordova (https://cordova.apache.org/) instead of native Android app SDK.

Hi Admin,

Let me understand.
If I am going to implement a websocket server in LM, I first create a resident script with this script under:
Do I have to change anything in this script or add something? 

Code:

local copas = require'copas'

-- create a copas webserver and start listening
local server = require'websocket'.server.copas.listen
{
  -- listen on port 8080
  port = 8080,
  -- the protocols field holds
  --   key: protocol name
  --   value: callback on new connection
  protocols = {
    -- this callback is called, whenever a new client connects.
    -- ws is a new websocket instance
    echo = function(ws)
      while true do
        local message = ws:receive()
        if message then
           ws:send(message)
        else
           ws:close()
           return
        end
      end
    end
  }
}

-- use the copas loop
copas.loop()
