Issue with both 1090 and 978 dongles

[Slipstream232]

problem I have is that for some reason both sticks wont work at same time. If I unplug the 1090 stick the 978 will work.

I`m using Bullseye image and followed this guide GitHub - abcd567a/rpi
I have both sticks serialized per guide.

I`m also using beast and feeding data to Flightradar24 , this part works fine for 1090

any recommendation what to do would be great.

I have installed tar1090 and it seems it is working but dump1090-fa nor dump978-fa is not active

perhaps I should uninstall tar1090? I have done a lot with this image so perhaps there is some other 1090 service running instead of dump1090 and dump978 but do not know how to find out.

here is a list of active running services. I think I need to remove something

when I click on 1090 it will show empty page

but IP/tar1090 will show this

I guess it would be easier to start over with a fresh install

Please post output of following commands:

sudo grep RECEIVER_SERIAL /etc/default/dump1090-fa   

sudo grep RECEIVER_OPTIONS /etc/default/dump978-fa   

&nbs;

@abcd567

sudo grep RECEIVER_OPTIONS /etc/default/dump978-fa

So far so good.
Now use following commands to determine serial number SAVED in eeprom Memory of the two dongles:
Replace 00x and 00y in 2nd & 3rd commands by values displayed in output of 1st command

lsusb | grep DVB-T

lsusb -v -s 001:00x | grep Serial

lsusb -v -s 001:00y | grep Serial

[Slipstream232]

@abcd567

lsusb -v -s 001:00x | grep Serial

[abcd567]

Great.
For both dump1090-fa and dump978-fa, the serial numbers in Dongle’s memory and in Pi’s config files are configured and matching. So we have eliminated the most probable and common cause of failure.

Now what? Let us try to find out.

[Slipstream232]

I have another problem, I did the initial install in Winter and placed antennad and RPI in my attic.

Well now there is 62C and the RPI with small Noctua FAN attached to it has 72C. I do not have any fan on the DVB-T sticks and they are so hot one could not even touch them.

I will have to figure out something else this setup won`t work for me.

[Slipstream232]

thank you Sir. I do not want to waste your time. This OS has many artefacts from my try end error era so I will do fresh Raspbian Lite install with latest Debian it will be easier

problem I have is that for some reason both sticks wont work at same time. If I unplug the 1090 stick the 978 will work.

The other most probable cause is Power Supply Unit gone bad and cannot supply enough current or proper voltage to run both dongles simultaneously.

Please conduct following simple check

• First with BOTH sticks
• Next with 978 Stick only

RPI - DC Low Voltage Check

sudo dmesg --ctime | grep voltage

If there is no output of above command, then Voltage is OK

You can’t have dump1090-fa AND readsb.

Choose one, both work.
Remove the other.

https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver

Running the automatic install for readsb will fix most common issues (fr24feed / rbfeeder being misconfigured, another decoder like dump1090 running).
It usually makes stuff just work (well a bit more complicated here with 1090 / 978 but if you configure readsb to use the correct serial it’ll be fine).

[Slipstream232]

yes I did install readsb the otherday as the guide has steps how to enable also Flightradar24

so I have removed everything piaware, dump1090-fa, dump978-fa, readsb

I would like to have Flightaware and Flightradar24 working on bullseye. what should I install? ( I was unable to find how to setup 978 with serial number on readsb

It’s all in the guide pretty much, there is a link to this about 978: (note that it has serials without all the zeros in the front, so use whichever serials you set already or set new ones without the zeros)
https://github.com/wiedehopf/adsb-wiki/wiki/Installing-dump978-fa-and-feeding-adsbexchange-with-UAT-traffic

Just follow the guide? It mentions FA and FR24 …

Thank you @abcd567 and @wiedehopf I have uninstalled the dump1090-fa and dump978-fa and reinstalled the readsb and I think the 978 is working although the piaware page shows amber
