Can't get dump 978 working

I installed 3.7.1 the other day and had an old 978 SDR laying around from a stratux build.

I ran the following commands from the directions:

sudo apt update
sudo apt install rtl-sdr
sudo systemctl stop piaware dump1090-fa dump978-fa

then

unplugged the 978 and did
rtl_eeprom -s 00001090

unplugged, replugged the 1090 and started over with the above, then ran 

rtl_eeprom -s 0000978

all returned OK

I then went to the quick start guide and ran

sudo piaware-config uat-receiver-type sdr
sudo piaware-config rtlsdr-device-index 00001090
sudo piaware-config uat-sdr-device driver=rtlsdr,serial=00000978
sudo reboot

here are my status returns

It seems the serial numbers assigned correctly, but it isn't starting dump978. Any ideas what I missed? It has to be something dumb. Sorry, don't know why the forum is formatting my post the way it is.
Also, when I try to go to IPaddress/8080 I get a 404 not found page, so it's like it just didn't install the packages? Perhaps my 978 SDR simply isn't compatible? It's one of these: https://www.amazon.com/Stratux-1090ES-UAT-Radio/dp/B01ENU1DQC/ref=sr_1_16?keywords=978+sdr&qid=1559156631&s=gateway&sr=8-16

You need to replug after assigning a number as well.
(Or remove power from the Rpi completely)

Otherwise it doesn’t take effect.

do you mean unplug and replug after

sudo piaware-config uat-receiver-type sdr
sudo piaware-config rtlsdr-device-index 00001090
sudo piaware-config uat-sdr-device driver=rtlsdr,serial=00000978

or after
rtl_eeprom -s 00000978

Because I did unplug and replug after assigned the serial to the SDR, and my output indicates that the write did take

pi@piaware:~$ rtl_test -t
Found 2 device(s):
0: Realtek, RTL2832U, SN: 00001090
1: Realtek, RTL2838UHIDIR, SN: 00000978

it’s a small hassle to keep crawling in my attic to get to my rpi and SDR’s

IPaddress:8080

Anwyay you want:

IPaddress/skyview978/

:8080 works
/skyview978 is a 404 not found

Let’s see this output.

sudo journalctl --no-pager -u lighttpd
sudo journalctl --no-pager -u dump978-fa

No port 8080 and port 80 are not the same place.

Did you start with the piaware sd-card or Raspbian sd-card?

You don’t seem to have dump978-fa installed.

Maybe just try:

sudo apt-get update
sudo apt-get upgrade
sudo apt install dump978-fa skyview978

I was running an older version and upgraded to 3.7.1 via the web portal. I’ll try and report back.

Let’s check the system version:

cat /etc/os-release

pi@piaware:~$ cat /etc/os-release
PRETTY_NAME=“Raspbian GNU/Linux 8 (jessie)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“8”
VERSION=“8 (jessie)”
ID=raspbian
ID_LIKE=debian
HOME_URL=“http://www.raspbian.org/
SUPPORT_URL=“http://www.raspbian.org/RaspbianForums
BUG_REPORT_URL=“http://www.raspbian.org/RaspbianBugs

from the web portal
Feeder Check-In: a few seconds ago
Feeder Type: PiAware (SD Card) 3.7.1

I’m not sure dump978 works on jessie.

Easiest would be to rewrite the sd-card with the current image from flightaware and just copy over your piaware-config.txt. (save before writing the image)
Then put in your feeder-id and you should have everything installed and running again.

Alternatively you can try to install the missing packages:

sudo apt-get update
sudo apt-get upgrade
sudo apt install dump978-fa skyview978

it’s working on get upgrade, it’ll take awhile.

that’s a real bummer, I have to crawl across the attic again if I reflash the card. :slight_smile:

it appears you’re right. I’ll reflash.

I suppose you can try installing the new repository


wget http://flightaware.com/adsb/piaware/files/packages/pool/piaware/p/piaware-support/piaware-repository_3.7.1_all.deb
sudo dpkg -i piaware-repository_3.7.1_all.deb

After that try the commands from before again :slight_smile:

(But yeah i suspect it’s only available for stretch)

Had to go to work, I’ll try it when I get home tonight and have ssh access again, thanks.

Yes, we only build dump978 packages for stretch. I haven’t tested building dump978 on older distributions, YMMV.

No dice, at least not for me. Oh well, I tried.

working fine after a reflash

No messages received yet, so either no one is flying on a UAT transponder in range, or the receiver is bad. Could go either way. I used this receiver for a stratux box and IIRC, I stopped using it because it was flaky, but it could have been the 1090 receiver, can’t remember.

The UAT traffic here in Toronto is occassional. I have Installed graphs to monitor it.
