localhost socket stuck with specific data ?

[admin]

Try this. It will try sending the data again if the first send call failed due to a closed socket or any other error. Remove log() calls once you get it working.

Code:

if not server then
  require('user.lutron')
  require('socket')

  server = socket.udp()
  server:setsockname('127.0.0.1', 5485)

  function send(data)
    if not sock then
      sock, err = lutron_login()

      if not sock then
        log('lutron login failed', err)
      end
    end

    if sock then
      res, err = sock:send(data)

      if res then
        return true
      end

      log('lutron send failed', err)

      sock:close()
      sock = nil
    end
  end
end

data = server:receive()
if data then
  if not send(data) then
    send(data)
  end
end
