“Piaware now sends mlat results to port 30104 by default. This change is to try to avoid accidentally feeding mlat results to a dump1090 that is not mlat-aware and may forward the results on unexpectedly (e.g. to other feeder software that doesn’t expect to see them).”
If you want MLAT results sent to dump1090-mutability you will need to complete one of two options.
1) EITHER have Piaware use the older default port 30004 to send data.
sudo piaware-config -mlatResultsFormat beast,connect,localhost:30004 sudo /etc/init.d/piaware restart
2) OR configure dump1090-mutability to listen for the data on the new port 30104.
sudo nano /etc/default/dump1090-mutability
Change the line BEAST_INPUT_PORT=”30004″ to BEAST_INPUT_PORT=”30104″ then reload dump1090-mutability.
sudo /etc/init.d/dump1090-mutability force-reload
