localhost socket stuck with specific data ?

[Hadeel]

Trying to work on this but I am still keep failing....
With the status script above(with 0 sec interval), I figured out new connection is open every 10 seconds.
I guess it is because of the timeout that I set inside lutron_connect script

Code:

function lutron_connect()
    local tcp = assert(socket.tcp())
    tcp:settimeout(10)
    local res, err = tcp:connect('172.16.1.10', 23)
  if res then
    return tcp
  else
    tcp:close()
    return nil, err
  end
end

What I have tried with modifying status script is as below but it creates an infite roop inside LM....
Appreciate a lot if you could help.
Thank you so much!

Code:

if not tcp then
  tcp, err = lutron_login()
  if not tcp then
    log('no connection to device', err)
end
end
while tcp do
  res, err = lutron_receive(tcp)
    if (res == nil) then
      return
    else
      log(res)
    end
     if (err ~= nil) then
        alert('Lutron error '..err)
    end
end
