Missing MLAT data on FlightAware

[FabioEight]

Hello,

I have an issue with docker-piaware and MLAT. I've configured my location on FA website and followed the instruction, but I'm unable to send MLAT data while other integrations are working (ex. RadarBox).

The current setup is: remote host with RTL-SDR dongle+antenna with readsb >>> other host with readsb and all integrations >>> feeding data.

My docker-compose on the host providing the data to feeds:

  readsb:
    image: ghcr.io/sdr-enthusiasts/docker-readsb-protobuf:latest
    tty: true
    container_name: readsb
    hostname: readsb
    restart: always
    ports:
      - 18082:8080
      - 30005:30005
    environment:
      - TZ=${FEEDER_TZ}
      - READSB_STATS_RANGE=true
      - READSB_NET_ENABLE=true
      - READSB_NET_CONNECTOR=neptune.fritz.box,30005,beast_in
      - READSB_NET_ONLY=true
    volumes:
      - readsbpb_rrd:/run/collectd
      - readsbpb_autogain:/run/autogain
    tmpfs:
      - /run/readsb
      - /var/log
      -

  piaware:
    image: ghcr.io/sdr-enthusiasts/docker-piaware:latest
    tty: true
    container_name: piaware
    restart: always
    depends_on:
      - readsb
    ports:
      - 18083:8080
    environment:
      - BEASTHOST=readsb
      - LAT=${FEEDER_LAT}
      - LONG=${FEEDER_LONG}
      - TZ=${FEEDER_TZ}
      - FEEDER_ID=${PIAWARE_FEEDER_ID}
      - ALLOW_MLAT=yes
      - MLAT_RESULTS=yes
    tmpfs:
      - /run:exec,size=64M
      - /var/log

docker-compose on the host using the RTL-SDR:

Any hint?

Thank you!

The screenshot you provided shows that you aren't synchronising with any nearby receivers.

Looking at the log you posted, there appears to be something wrong with the BEAST connection to readsb.

Can you describe the network between your two hosts?

You could also try setting the BEASTHOST variable for your piaware container to neptune.fritz.box (which I assume is your readsb instance with the SDR attached).
