Arcam control over ip

[Thinklight]

Try this:

Code:

12345678910111213141516171819202122232425262728

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?
