Help with broken ADS-B after addition of UAT978

[fminton]

Hello all

I have been running a dump1090 for some time now and I just added a radio for UAT978. I followed the instructions on one of the discussion pages and entered the following commands after I plugged the orange flightaware receiver into the Pi.

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

Then sudo reboot

Piaware starts but neither the 1090 or 978 comes up.

Here is what I get with the status inquiry

Any ideas what I am missing?

Piaware starts but neither the 1090 or 978 comes up.

You have used rtl_eeprom to change the serials to the correct ones?

[fminton]

Ok I just found those commands and performed them.

rtl_eeprom -s 00001090

rtl_eeprom -s 00000978

unplugged, replugged and re-booted still no joy

[wiedehopf]

@fminton

Ok I just found those commands and performed them.

You understand you must only have one SDR plugged in for each command?

[fminton]

I just tried again, confirmed one dongle at a time and the 1090 is back to working but still 978 is still down.

[wiedehopf]

@fminton

sudo piaware-config uat-sdr-device driver=rtlsdr,serial=00000978

Are you sure that’s what was in that thread?
Can you quote the relevant post from that other thread maybe?

6 - Configure UAT 978

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

# Reboot Pi to implement configuration settings
sudo reboot

 

From Piaware advance configuration page:

Setting name	Possible values	Default value	Description
uat-sdr-device	see link in description	driver=rtlsdr	configures the sdr device to use in UAT mode; supported values can be found on the SoapySDR github page

 

From SoapySDR Settings page on Github

Device string examples

Here is how to use RTLSDR dongle via SoapySDR library with SoapyRTLSDR plugin:

device_string = "driver=rtlsdr,rtl=0";

Same thing, but identifying the device with its serial number:

device_string = "driver=rtlsdr,serial=00000349";

How to Install and Configure Piaware 5.0 SD card image - Quickstart Guide

1 - Download and write Piaware SD card image on a microSD card. http://piaware.flightcdn.com/piaware-sd-card-5.0.img.zip Note: When you first boot the image it will look and act like a normal 1090 MHz PiAware. Only in case you want to activate the 978 Mhz features, carry out Steps 5 and 6 below, otherwise skip Steps 5 & 6. 2 - Enable SSH & WiFi While the microSD card is still in the card reader of your Laptop/Desktop, in File Explorer (Windows) or Finder (Mac) click on drive letter of the mi…

Did you reboot your Pi after issuing configuration commands shown above?

[fminton]

Ok I think I have the serialized properly but getting an error

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

Using device 0: Generic RTL2832U
usb_claim_interface error -6
Failed to open rtlsdr device #0.

[abcd567]

First stop all to free the dongles for test

sudo systemctl stop piaware dump1090-fa dump978-fa   

Now test dongle 0
rtl_test -d 0 -t

Next test dongle 1
rtl_test -d 1 -t

After tests are finished, reboot Pi to restore system to normal
sudo reboot

[fminton]

Ok this is what I got

first when I stopped everything I received this:

pi@piaware:~$ sudo systemctl stop piaware dump1090-fa dump978-fa

Failed to stop dump978-fa.service: Unit dump978-fa.service not loaded.

Then testing the dongles

Dongle 0

pi@piaware:~$ rtl_test -d 0 -t

Now Dongle 1

pi@piaware:~$ rtl_test -d 1 -t

I then rebooted

Failed to stop dump978-fa.service: Unit dump978-fa.service not loaded.

Your dump978-fa installation has some issue as indicated by above responce.

What is output of following command?

apt policy dump978-fa

[fminton]

pi@piaware:~$ apt policy dump878-fa

E: Invalid operation policy

[abcd567]

Seems your distro is very old. Try this

apt-cache policy dump978-fa

If above also fails, try with sudo

sudo apt-cache policy dump978-fa

[fminton]

It says unable to locate package dump978-fa. I’m on version 4.0

[abcd567]

What is output of following command?

cat /etc/os-release

[fminton]

pi@piaware:~$ cat /etc/os-release

It says unable to locate package dump978-fa

The dump978-fa did NOT get installed. What method/command you used to install it?

 

@fminton

PRETTY_NAME=“Raspbian GNU/Linux 8 (jessie)”

You have jessie, too old.

I am not sure if dump978-fa ver 4.0 can be insalled on it. @obj can confirm this.

[fminton]

From what I had seen on here I assumed it was already installed. I just tried to install it:

sudo apt-get install dump978-fa
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package dump978-fa

looks like I need to start over with a new distro
