  • MLAT not running

    Hi guys

    I've got a Raspberry Pi 2b and a Pi 4 4gb and both show MLAT no

    I've setup as per the guide and rebooted thinking it needed a reboot but to no avail. Could someone point me in the right direction to get MLAT going please?

    To add

    I've found the following in my log file

    2019-12-26 20:45:46 | [mlat][e]Receiver not compatible with MLAT, timestamps in wrong format![time][i]Time synchronized correctly, offset -0.006 seconds

    Its a brand new Pi. What am I doing wrong

    So it thinks the receiver isn't capable. What do you have?

    If it's a USB Stick. And you configured for avr-tcp:30002

    It needs to be beast-tcp:30005

      Thank you I've got a flightaware pro dongle. I've just suggest what you've said and I'll report back.

        To add.

        I've going to the settings page, edited the settings and it reverts back.

          You have to select save 2x (known bug)

          If it still doesn't, and you used the fr24 image, it is possibly in write only state.

          There's a command to revert back to rw somewhere

            Give these 2 commands and then try change settings.
            NOTE: Dont forget to click Save button on bottom-right of settings page IP:8754/settings.html

            Code:
            sudo mount -o remount,rw /
            sudo chmod 666 /etc/fr24feed.ini

              No such luck!

              Is there a manual way to edit the file?

                Is there a manual way to edit the file?
                Code:
                sudo nano /etc/fr24feed.ini
                When above command is issued, a file will open with following text.
                Change receiver= and host= settings as shown below.

                Code:
                receiver="beast-tcp"
                host="127.0.0.1:30005"
                fr24key="xxxxxxxxxxxxxxxx"
                
                bs=no
                raw=no
                mlat="yes"
                mlat-without-gps="yes"
                After editing, Save (press Ctrl and o keys togather), then close file (press Ctrl and x keys togather.

                Now restart fr24feed

                Code:
                sudo systemctl restart fr24feed

                  You sir, are a gentleman and a scholar.

                  I'm now getting

                  Aircraft Tracked:
                  (ModeS & ADS-B)
                  1
                  Aircraft Uploaded: 0
                  Receiver: beast-tcp, Connected
                  MLAT running: YES
                  I guess the aircraft I've tracked has been disregarded and not uploaded.(EDIT TO ADD: Its just uploaded some aircraft)

                  Reason the number is low is because the aerial is behind my TV as I've not managed to climb my roof to install it yet.

                    Place it in a window, that can get somewhat ok results.

                    If you have any more configuration trouble, this script of mine fixes it most of the time: https://github.com/wiedehopf/adsb-sc...for-dump1090fa
                    (also gives you a choice of multiple web interfaces)
