Raspberry Pi type B + DVB-T Dongle to feed FR24

[marke]

I have been using a Raspberry Pi 3 for some time with good results, but all of a sudden, the ON Line time has dropped dramatically and the raspberry Pi goes permanently OFF Line. Rebooting the Raspberry Pi will get it going again, but not reliably. Is it possibly a SD card problem??

Thanks for your help. The error changed in:

Found 1 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000001 (currently selected)
usb_claim_interface error -6
Error opening the RTLSDR device: Device or resource busy

Either didn't reboot the pi, or you have crashed dump1090 (or have something other than just fr24feed) running.

If you search here for the exact term youll find the likely caused and how to confirm of reboot does not

Hi all, I've installed software on my raspberry and put usb dvb-t dongle and on ssh it seems to be working. Fr24feed shows something like this:
[ATTACH=CONFIG]8853[/ATTACH]

And on service fr24feed i am seeing this:
[ATTACH=CONFIG]8854[/ATTACH]

On the site it is still offline and no plane was updated so far.

I am using raspberry pi3 b and a "not only tv" dvb-t usb dongle and stock antenna outside my apartment.

Any help would be nice becouse i dont know what i am doing wrong

Unfortunately it is just another standard tv tuner.

Notice the fc0013 tuner found?

It needs to be a Rafael 80x tuner. It won't receive adsb Signal

These pings suggest that your receiver might not be receiving any signal. Can you move your antenna to a better spot, preferably outside?

It is outside and i live near an airport and planes are really close so i dont know what is the problem.
But is the sofware and Raspberry working properly?

Check the log file with tail -f /var/log/fr24feed.log. This will provide more info.

Never had to add the vendor specifics to the file. Only the un-blacklist.

Including SUDO infront of each command? else its normal user and wont have high access
sudo fr24feed start

Yup, tried it with sudo.

I'm using the Pi24 image, and when I'm running 'fr24feed' I get the following error:

Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules
Error opening the RTLSDR device: Permission denied


Tried adding:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", MODE:="0666"
to /etc/udev/rules.d/rtl-sdr.rules.

And:
lacklist dvb_usb_rtl28xxu
blacklist e4000
blacklist rtl2832
blacklist rtl2838
blacklist RTL2838UHIDIR
to /etc/modprobe.d/rtl-sdr-blacklist.conf

Any ideas?

Thanks Oblivian, your post tipped me in the right direction. I was able to figure it out; everything is up and running!

During the install I had installed an instance of dump1090-FA (I thought I had uninstalled it once I realized that it was Flight Aware specific...alas I had not). It was running in the background and stealing the dongle.

I've had it up and running in its enclosure for a day now (to keep an eye on temps in the sealed enclosure). Hopefully this week I'll get the antenna built, get the feed up and running to Flight Radar, then get everything mounted up on the roof.

what version of raspbian do you have? i had the same problem for long time ago, but since i upgrade rpi to new pixel the problem was solved.
