(Bearing in mind my knowledge of all things Linux is approx zero)
Was messing about with a headless Pi running (happily!) piaware when a saw a screen with lots of error messages scrolling by about not able to connect to a 978MHz. Presumably this is wasting resources and it doesn’t work (?) in the UK anyway. Is there something I can tweak to put it out of its misery?? Thanks in advance!
How did you install it? Piaware ISO image or Piaware package on top of Raspberry OS?
978 is disabled by default AFAIK
Err… I’ve done so much recently that I honestly forget! Pretty sure it’s just the iso. That said, I found an old QuickStart guide linked by @abcd567 that listed the process - which I’ve tried. Problem is I can’t recall where I saw the error messages, so I don’t know if what I’ve done has done anything!
Commands used were:
sudo piaware-config receiver-type rtlsdr
sudo piaware-config uat-receiver-type none
sudo systemctl restart piaware
Please don’t tell me I’ve screwed it royally!
As you are in UK, and dump978 is not required in UK, these are correct commands and the error message for piaware not being able to connect to dump978 should stop. Seems the 2nd command did not execute. Please re-issue following commands
sudo piaware-config uat-receiver-type none
sudo systemctl restart piaware

If in case you have installed dump978-fa unknowingly, you can remove it by following commands:
sudo apt purge dump978-fa
sudo apt autoremove
sudo reboot

Hmmm… those last three didn’t go well! Gone from three greens to three reds.
Getting this:
● piaware.service
Loaded: masked (Reason: Unit piaware.service is masked.)
Active: inactive (dead)
Now what?

Thanks, looks better but still three reds

I’m guessing the “exited” entries are a problem in the above.

The service shows “active” so, this is first ok.
Please print the last lines of this command:
journalctl -xe|grep piaware
Last lines are:

Which, strangely is where this all started, me seeing the 978 reference!! I’m guessing the 978 error isn’t behind the current issue.
Exit code 5 = Program is not installed.
Seems somehow the piaware package got uninstalled.
What is the output of following command?
apt-cache policy piaware
LSB service exit codes

You have installed dump978-rb from Radarbox24.
This happens when while installing Radarbox24 feeder you have said “yes” to option presented (yes/no) to install dump978-rb.
Please uninstall it by following command:
sudo apt purge dump978-rb
sudo reboot
Also make sure in file /etc/rbfeeder.ini , the line #dump978_enabled=true is commented out, as shown in screenshot below:
sudo nano /etc/rbfeeder.ini

Commented out (was already)
Appreciate all the help you’re giving!
Install piaware
sudo apt install piaware
sudo piaware-config feeder-id xxxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxxx
## In above command replace xxxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxxx
## by your actual feeder-id
sudo piaware-config allow-manual-updates yes
sudo piaware-config allow-auto-updates yes
sudo systemctl restart piaware
All done, those two updates were already set to yes ( said ‘unchanged’)
Now seeing two greens, expect the last one (MLAT) will change shortly
Guess I’m sorted now!
Really grateful @abcd567 @foxhunter

Still just the two greens, MLAT is red and the ? gives “MLAT disabled/not synchronised/Latitude Longitude not set”
Not seeing any aircraft and the link to view live data just gives a 404 on local IP
Presumably something still not right?

Seems dump1090-fa is not installed.
What is output of following commands?
apt-cache policy dump1090-fa

Three greens and aircraft logging. Viewing live data shows as expected.
Think we’re there. I’m gonna do a copy of the SD card just in case!
