Need help with my ADS-B dongle

FlightAware ADS-B Flight Tracking
1

Hello, I am running flightradar24 software on raspbian stretch (not flightradar image). I posted here since I’d like all the help I can get. My USB dongle seems to disconnect. What I also find is that it only tracks flight for the first few seconds on boot up. Here is when i plug in the dongle + errors:

It looks like you could have a power problem.
Make sure that you use a quality 2.5 Amp power supply.
The new RPI 3B+ is more susceptible to power issues. I have POE adapters that work fine the RPI3 but not with the RPI 3B+.

I bought a Raspbian Dongle first and had so much trouble with it and few answers I sold it on eBay and just ordered the flight tracker from flight aware. I even tried to use it as a portable one in my car and could not track much of anything. Get an antenna and set it up on the roof in a clear view of the sky no trees or try for the highest point you can get. It may be location, location location is your issue not sure as I do not know the whole story but as I said the Raspbian one I had sucked.
The flight aware one was free and they delivered it with lots of extra cable so I could put it on my chimney. It came super fast with everything you need to operate it.

I dont think so as the previous power supply I had undervoltaged during bootup and normal use several use, this power supply only had 1 undervoltage in over 1000seconds.

6

At te moment im not worried about my antenna, im worried about my dongle.

try this:

sudo nano /etc/modprobe.d/blacklist.conf

add the following two lines

blacklist rtl2832
blacklist dvb_usb_rtl28xxu

then CTRL-O to save and CTRL-X to exit

sudo reboot

Then check again.
But yes it might well be a problem with the power.
Just because your previous dongle did work doesn’t mean much as the new dongle might be using more power.

Are you using an usb extension?
Also try another usb port.

Nothing wrong with my OS, its the USB dongle. My Raspberry Pi receives enough power, i showed the dmesg output above, it recognizes it at first, but then it drops off after 600+ secs

10

Just because the pi works with the existing power does not mean that the dongle will work when the voltage sags every now and then.

11

There are a bunch or already posted answers on here for Dongle issues but if it is not a power issue then most likely it is an SD card issue. If you get some packets but not a lot of them then that’s probably an antenna issue but if your not getting anything then it is most likely power or SD card. If it is a RF issue you will still get some packets thru.It is

12

It had an undervoltage once during that boot, I have rebooted my pi, recieved the same errors except that this time there was no undervoltage.

13

Definitely not a SD card issue, I can access the the OS fine. I receive a link at the start of boot, I don’t know why it after that no aircraft are found.

14

Ok then that leaves only about one thing and that’s the WIFI connection. If it fires up sends a good signal and then the signal drops my best guess is the WIFI is dropping out of it for some reason…

15

The logs he posted are not consistent with wifi problems.

Either the dongle is crap or it’s not getting enough power or it is connected via some stupid USB extension cable.

You can try the dongle on another computer.

Try a new power supply. It really does not take much deviation bit a bad cable can cause it also.

If you just google the error code it comes up as bad power supply or cable with this error code.

18

Just replugged the dongle back into my pi, and the dongle recieved 57 locations then no more after that.

19

I just waited 2 weeks for a power supply from ebay. So id like to see what other people have in mind.

Did you try the blacklisting as well?
Did you try the dongle on another computer?

Good luck (not that i imagine that you will be any different answers)
