dump1090-mutability - no MLAT displayed

I have updated my piaware image with dump1090-mutability and there are a few issues I am seeing:

  1. The map no longer displays MLAT aircraft (the blue ones in the list).
    The MLAT system itself works, I can see that I am pushing MLAT information to FlightAware and the log shows:

03/26/2016 00:33:45 mlat(2521): Receiver status: connected
03/26/2016 00:33:45 mlat(2521): Server status: synchronized with 43 nearby receivers
03/26/2016 00:33:45 mlat(2521): Receiver: 116.4 msg/s received 2.3kB/s from receiver
03/26/2016 00:33:45 mlat(2521): Server: 0.8 kB/s from server 0.0kB/s TCP to server 0.8kB/s UDP to server
03/26/2016 00:33:45 mlat(2521): Results: 347.1 positions/minute
03/26/2016 00:33:45 mlat(2521): Aircraft: 2 of 11 Mode S, 2 of 3 ADS-B used

How do I enable MLAT based aircraft in the map?

  1. dump1090-mutability is not creating the noise rdd file for collectd. I have removed all those lines for the noise grapg in the config but would still like to see it working.
    Is there a way to enable writing the file?

Which version of mutability are you using?

I am using Version 1.14.

Check that dump1090 is listening on port 30104 for MLAT results from PiAware.
In the file /etc/default/dump1090-mutability check that the BEAST_INPUT_PORT setting is set to 30104.

Someone correct me if I’m wrong – but I think only the 1.15 dev version of mutability creates that display for the mlat hits…aside from the vanilla dump1090 in the FA install instructions. I’m still on 1.14 as well. I’ve managed to get the mlat planes to show on the map, but they’re not differentiated from the ads-b ones by color.

Just a quick update -

I ended up getting the ADSBReceiver image and re-installed everything. Now I can see different color for MLAT only flights along with all performance graphs working.
