TCP Socket Connection for Legrand

[a455115]

Okay, I get it.

I used the sample TCP code:

Code:

function read(sock)
  local buf = {}

  while true do
    local ch, err = sock:receive(1)

    if ch then
      local pr = buf[ #buf ]

      buf[ #buf + 1 ] = ch

      if ch == '#' and pr == '#' then
        break
      end

    else
      return nil, err
    end
  end

  local ret = table.concat(buf)
  log(ret)
  return ret
end




-- init socket
if not sock then
  require('socket')

  sock, err = socket.connect('192.168.1.247', 20000)

  -- set timeout to 1 second
  if sock then
    sock:settimeout(1)
  -- error opening connection, log error and wait before reconnecting 
  else
    error(err)
    sleep(5)
  end
end

-- socket handler
if sock then   

sock:send('*99*1##')
 
 
 
--data = sock:receive(14)
   res, err = read(sock)
 
 
 
--sock:send('*#1*12##')
-- log('check')
-- sock:send('*1*1*12##')
  -- got data, log it
  if data then
    log(data)
  end
end

 and I'm currently getting this:
* # 4 * 1 * 0 * 0229 ## in log.
Which means that the temperature of thermostat 1 is 22.9 degrees. How to separate the digit with the code 1 to be address 32/1/1 and write the value 22.9 in it? How do I separate receiving and sending commands so that it works properly?
