Arcam control over ip

[Thinklight]

Try this:

Code:

function tcp_arcam(data, ip, port)
 local sock, res, err, len

 sock = require('socket').tcp()
 sock:settimeout(1)

 res, err = sock:connect(ip, port or 50000)
 
 if res then
   -- send data
   sock:send(data)

   -- receive response
   res, err = sock:receive(5)
   if type(res) == 'string' and #res == 5 then
     len = res:byte(5)
     res, err = sock:receive(len + 1)
   else
     alert('receive failed: ' .. tostring(err))
   end
 else
   alert('connect failed: ' .. tostring(err))
 end

 sock:close()

 return res, err
end

I am got nil and timeout. What you think whats wrong?
