KryoNet sending at an interval

Hello,
I’m trying to send packets after a cycle that runs @ 20hz
But I’m having trouble with it, currently I’m just using the KryoNet server.start() method.
As soon as I receive a packet I sent a response. What I want is having that response being sent after one game loop cycle has been handled. So the server would broadcast every 20hz instead responding immediately.

I’m not sure if I should do it every 20hz or respond immediately. Any suggestions?
