OPPO control over IP

[Thinklight]

Hi control is working but I am get respond with timeout. why?
Command function:

Code:

function tcp_oppo(data, ip, port)
 local sock = require('socket').tcp()
 sock:settimeout(3)

 local res, err = sock:connect(ip, port or 23)
 
 if res then
   res, err = sock:send('#' .. data .. '\r')

   if res then
     res, err = sock:receive('*a')
   else
     alert('send failed: ' .. tostring(err))  
   end
 else
   alert('connect failed: ' .. tostring(err))
 end

 sock:close()

 return res, err
end

Event:

Code:

ip = '192.168.11.105'

if (event.getvalue() == true) then
 res, err = tcp_oppo('POW', ip)
end
log (res, err)
