how to reply a UDP socket in NiFi (ListenUDP & PutUDP) or Custom Processor


I would like to reply a message to a UDP using the same socket from a received packet in NiFi. I am currently using ListenUDP, but I believe this is not possible.

Thus, is that possible? Any hints?

Thanks and regards,

Hi Gustavo,

Did you find a solution ?

I'm also looking for sending a acknowledge to the udp sender. I 'm able to get udp.sender and port.sender attribute, but i'm not able to use in putTCP configuration

thanks and regards,
