Arylic integration via TCP API

[admin]

Here's an example of sending commands:

Code:

function encodeuint32(value)
  local bytes = {}

  for i = 1, 4 do
    bytes[ i ] = bit.band(value, 0xFF)
    value = bit.rshift(value, 8)
  end

  return string.char(unpack(bytes))
end

function encode(cmd)
  if #cmd > 11 then
    cmd = cmd .. '&'
  end

  local csum = 0
  for i = 1, #cmd do
    csum = csum + cmd:byte(i)
  end

  return
    string.char(0x18, 0x96, 0x18, 0x20) ..
    encodeuint32(#cmd) ..
    encodeuint32(csum) ..
    string.char(0x00):rep(8) ..
    cmd
end

sock = require('socket').tcp()
sock:settimeout(5)

res, err = sock:connect('192.168.1.1', 8899)
if res then
  data = encode('MCU+VOL+050')
  sock:send(data)

  log('send ok')
else
  log('connection failed', err)
end

sock:close()

For full integration the response must be parsed. Since the device can only handle a single TCP connection you will need a resident script that handles both sending commands and receiving status message from the device.
