    Exclamation Receiver is online but not sending any data

    Receiver is online but not sending any data (no aircraft in coverage or problem with antenna) - have found out this error today. Used to work just fine.

    I reconfigured the settings and updated the system but no luck so far. I'm using DVT-B USB stick (WINGONEER Digitale USB 2.0 DVB-T SDR+DAB+FM RTL2832U+R820T2).

    Checking the status:
    Code:

    Please post the output of

    cat /etc/fr24feed.ini

    Don't post the fr24key though that should remain private.

    If a log path is set please have a look into the log if you know how

    If you want to manually start the feeder for testing you need to stop the service first like this:
    systemctl stop fr24feed
    (otherwise the dongle is already used by the service, it can't be used twice)

    I have the same issue. How do we get the Pi to recognise the receiver?

    Restart for a start. The auto upgrade is enabled and likely didn't shut everything down as it is meant to
    Therefore you are possibly starting 2 copies and RTL set hadn't restarted

    If not it would point to something else the updater had broken

    But we would see a lot more offline if that was the case

    So its likely more isolated to your common set ups and need more individual tests

    Thanks Oblivian. My Raspberry Pi sd card died during the week and I put an image on a new sd card and reactivated everything this morning. Have had an issue with not seeing anything for a while. very frustrating.

    So can you then fill us all in with the details...

    Config/stick setup settings
    Reboot performed yes/no?

    Remember don't run anything related to 'fr24feed' after rebooting. Only ever look at the web status page or run the correct status command. Anything else will just re-run and break.

    And it is not clear if what you pasted is a log, or re running it which will give that output if you don't stop it first per the command given by wiedehopf

    And I suspect it's the latter. Or you wouldn't see

    [bs][e]Could not bind socket to *:30003, errno=98

    That means already open.

    Thank again. i may be tech savvy with a lot of things but Linux and the Raspberry Pi are not them.

    Rapsberry Pi with the FR24 image loaded and activated
    Tuner - Unsure of the Brand as I purchased it on eBay: USB2.0 Digital DVB-T SDR+DAB+FM HDTV TV Tuner Receiver Stick RTL2832U + R820T
    Have just rebooted the Pi and logged in via the web portal 192.168.0.7:8754
    Screen Shot 01-19-19 at 02.25 PM.jpg

    Antenna is located on the roof, but is just the mag base antenna that came with the tuner.

    Id be surprised if there was 214 users in that immediate area. So someone has maybe reactivated wayyyyy too many times.

    The image and activation should really only be used once and manual setup every consecutive time after to be sure it uses the same key/id. The default antennas are insensitive to adsb without being trimmed btw. One user has it on a tin roof and only gets out to ~60nm

    So are you sure there are enough in that range? Reactivating a new unit will need 3-4 or so contacts to go true live if that restriction is still in place.

    Click the settings page. Enable the log.

    Restart pi

    Run the command supplied to view the active log after it's been run for a a few mins.
