I am listening data from GPS devices I want to listen this datas into ListenTCP .
1.Device is sending data through only TCP
2.ListenTCP is not listening that data.
If you have any other alternative solutions also let me know for how to listen TCP data?
We need more information to provide a more specific answer to your question.
That said, I would recommend that you first ensure the TCP port is operational from the server running NiFi. I would do this by accessing command line on the NiFi node and testing that it has access to the port and can see new TCP data in your terminal. Next you can confirm the Local Network Interface and Port is properly configured in ListenTCP Processor. Now run the processor and tail the nifi log for any additional warning or errors.
