SOLVED. UAT-only receiver not aquiring data

FlightAware ADS-B Flight Tracking
1

I have installed on a dedicated Pi3 the piaware and dump978.
Setup with piaware-config:

pi@pi3:~ $ sudo piaware-config
allow-auto-updates yes # value set at /etc/piaware.conf:7
allow-manual-updates yes # value set at /etc/piaware.conf:8
receiver-type none # value set at /etc/piaware.conf:10
uat-receiver-type sdr # value set at /etc/piaware.conf:9

Well, I get no traffic from the SDR receiver. The antenna signal is splitted to a UAT flight-feeder and that one sees planes.
The flightaware website for that site has three green ā€œflagsā€.
Any ideas?

LE: I have marked this thread as ā€œSolvedā€ because my issue was solved.

It seems that dump1090-fa is activeā€¦ donā€™t know why.

pi@pi3:~ $ piaware-status
PiAware master process (piaware) is running with pid 542.
PiAware ADS-B client (faup1090) is not running.
PiAware ADS-B UAT client (faup978) is not running (disabled by configuration settings)
PiAware mlat client (fa-mlat-client) is not running.
Local ADS-B receiver (dump1090-fa) is running with pid 541.

dump1090-fa (pid 541) is listening for ES connections on port 30005.
faup1090 is NOT connected to the ADS-B receiver.
piaware is connected to FlightAware.

dump1090 is producing data on localhost:30005.

Give command
sudo systemctl restart piaware

OR better
sudo reboot

Then check status.

Itā€™s still running the dump1090-fa!

pi@pi3:~ $ sudo systemctl restart piaware
pi@pi3:~ $ piaware-status
PiAware master process (piaware) is running with pid 1105.
PiAware ADS-B client (faup1090) is not running.
PiAware ADS-B UAT client (faup978) is not running (disabled by configuration settings)
PiAware mlat client (fa-mlat-client) is not running.
Local ADS-B receiver (dump1090-fa) is running with pid 801.

dump1090-fa (pid 801) is listening for ES connections on port 30005.
faup1090 is NOT connected to the ADS-B receiver.
piaware is connected to FlightAware.

dump1090 is producing data on localhost:30005.

piaware wonā€™t control that unless itā€™s the piaware sd-card.

Disable the service or uninstall dump1090-fa.

I though that dump1090-fa is needed to ā€œtranslateā€ the dump978-fa and bring in the lighttpd? On flightaware page is not clear.

Anyway, the dump978-fa is still disabled:

pi@pi3:~ $ piaware-status
PiAware master process (piaware) is running with pid 1424.
PiAware ADS-B client (faup1090) is not running.
PiAware ADS-B UAT client (faup978) is not running (disabled by configuration settings)
PiAware mlat client (fa-mlat-client) is not running.
Local ADS-B receiver (dump1090) is not running.

no program appears to be listening for ES connections on port 30005.
faup1090 is NOT connected to the ADS-B receiver.
piaware is connected to FlightAware.

got ā€˜couldnā€™t open socket: connection refusedā€™
dump1090 is NOT producing data on localhost:30005.

sudo systemctl enable dump978-fa  

sudo systemctl disable dump1090-fa  

sudo reboot

This seemed to temporarily fix a UAT-978 pi that was receiving 1090 instead of 978 but ended up reimaging it
sudo systemctl stop dump1090-fa
sudo systemctl restart dump978-fa

the presence of dump1090-fa running seemed to block dump978-fa from working

PiAware ADS-B UAT client (faup978) is not running (disabled by configuration settings)

Where are those ā€œconfiguration settingsā€?

10

stop and restart commands are temporary, and piaware will attempt and restart it. Further, it will be lost with reboot.

Use disable and enable followed by reboot. This will survive piawareā€™s attempt to restart, and survive subsequent reboots

piaware-config should list where the settings came from

12

stop and restart might be useful for troubleshooting without rebooting

13

I have unistalled dump1090-fa, rebooted and the piaware-status shows the same.
However, on the skyaware webpage now I see the UAT plane.

piaware-status from working uat receiver:
PiAware master process (piaware) is running with pid 20467.
PiAware ADS-B client (faup1090) is not running (disabled by configuration settings)
PiAware ADS-B UAT client (faup978) is running with pid 20508.
PiAware mlat client (fa-mlat-client) is not running.
Local ADS-B UAT receiver (dump978-fa) is running with pid 1663.

dump978-fa (pid 1663) is listening for UAT connections on port 30978.
faup978 is connected to the ADS-B UAT receiver.
piaware is connected to FlightAware.

dump978 is producing data on localhost:30978.

Somehow it started working here too:

pi@pi3:~ $ sudo piaware-status
PiAware master process (piaware) is running with pid 1424.
PiAware ADS-B client (faup1090) is not running (disabled by configuration settings)
PiAware ADS-B UAT client (faup978) is running with pid 1468.
PiAware mlat client (fa-mlat-client) is not running.
Local ADS-B UAT receiver (dump978-fa) is running with pid 1459.

dump978-fa (pid 1459) is listening for UAT connections on port 30978.
faup978 is connected to the ADS-B UAT receiver.
piaware is connected to FlightAware.

dump978 is producing data on localhost:30978.

was there an an auto-update overnight? i started getting dump978-fa errors at 6:00 am ET.

restarting brings things back temporarily, but then dump978-fa starts failing again.

i didnā€™t make any changes leading up to the system failing.

17

No.

May be hardware failure then, power supplies are the usual culprit for gradual failures.

18

huh. all the components are brand new. i just set them up ~48 hours ago and generally have clean power here.

iā€™ll keep debugging.

19

dmesg might list a power supply issue

Well, wait, if itā€™s a brand new system then you donā€™t really have enough data to say that it was working ā€œbeforeā€, because there wasnā€™t much ā€œbeforeā€.
