    NO DATA problem even if everything is ok but..

    Hi folks,
    I've a little problem with my Raspberry with flightradar24 feeding.

    The daemon is working correctly, nothing on the logs... but sometimes in a completely random behaviour, I saw on the data sharing link on FR24 website that my RADAR is sending NO DATA.

    As soon as I log on the Raspberry everything seems to be ok.

    pi@raspberrypi:~ $ sudo service fr24feed status -l
    ● fr24feed.service - Flightradar24 Decoder & Feeder
    Loaded: loaded (/etc/systemd/system/fr24feed.service; enabled)
    Active: active (running) since Mon 2019-05-13 17:52:51 CEST; 7min ago

    May 13 17:52:51 raspberrypi systemd[1]: Started Flightradar24 Decoder & Feeder.


    OR

    pi@raspberrypi:~ $ sudo fr24feed-status
    [ ok ] FR24 Feeder/Decoder Process: running.
    [ ok ] FR24 Stats Timestamp: 2019-05-13 16:00:14.
    [ ok ] FR24 Link: connected [UDP].
    [ ok ] FR24 Radar: OBFUSCATED1.
    [ ok ] FR24 Tracked AC: 1.
    [ ok ] Receiver: connected (111 MSGS/0 SYNC).
    [ ok ] FR24 MLAT: ok [UDP].
    [ ok ] FR24 MLAT AC seen: 0.
    pi@raspberrypi:~ $


    but continues to be NO DATA till I reboot the Raspberry.

    Two questions:
    1) what is the problem and where can I find what's going on ?
    2) why the diagnostic says that everything is ok even if the module is sending NO DATA?

    Regards

    Federico

    USB Stick 'wedging'. The internal chips likely turning off.

    Often due a fault or power issue.

    since Mon 2019-05-13 17:52:51 CEST; 7min ago - you were 7mins late in noticing or checking why.

    I trust what you saying, but what do you suggest to do? Schedule an automatic reboot?
    The problem is totally random...

    The test is usually. Try a 2nd stick. Or power supply
